ASK THE EXPERT

Nigel Skinner PhD, Head of Marketing, Andrew Alliance, Geneva, Switzerland

Andrew Alliance is a shining example of “innovation” in all respects. Accordingly, we have been recognized for this through numerous awards since our founding in 2011, most recently including an award from the Swiss Institute for Quality Testing (October, 2020), a product leadership award from Frost & Sullivan (Sept, 2019) and New Product Innovation Awards from the Society for Laboratory Automation & Screening (Feb 2019).

What trends are driving innovation in the field?

The drive to deliver precision medicine and translational research places ever higher demands – and standards – on research, with expectations on evermore precise data. This requires superior productivity, with greater precision and less errors, and drives innovation in workflow execution.

How has COVID-19 impacted your ability to innovate in 2020?

Andrew Alliance has supported customers developing COVID-19 vaccines, as well as both serological and PCR-based tests, throughout lockdown. Those customers have appreciated our cloud-native software for the remote setup and operation of our liquid handling automation from, from example, their home office. Moreover, it has emphasized the benefits of our unique approach to innovation – an agile development process capable of rapidly translating innovations into products that can be installed, trained and supported remotely.


MET ONE 3400+ AIR PARTICLE COUNTER

Automates and simplifies routine environmental monitoring for GMP cleanroom compliance by integrating innovative features “all inside the box”

The new MET ONE 3400+ enables users to import routine environmental Standard Operating Procedures (SOP) into the counter, creating an interactive SOP map on the counter screen itself, which guides technicians to each sampling location. It automatically configures the counter according to the user’s SOP, which helps reduce human error and improve data integrity.

All electronic records inside the counter are reviewed and approved — using electronic signatures — via a web browser, then exported via Ethernet. Administrators can also manage SOP version control remotely through a web browser.

“Because everything is ‘in the box,’ managing even complex SOPs can be greatly simplified,” says Carter Moursund, Senior Product Manager. “Using a web browser interface, QC professionals can customize their electronic SOPs and maps, and change or update them quickly and easily. Plus, thanks to a new ‘plug-nplay’ networking feature, all SOP modifications are automatically replicated on all counters in use.”

Interactive, on-screen tracking instantly shows on-site users which locations have been sampled, allowing them to monitor their progress at a glance.

After on-site monitoring, professionals then “sign” sampling reports via electronic signature. Reports can be exported in a secure electronic format to their network or a USB device. Thus, the MET ONE 3400+ supports compliance with the FDA’s 21 CFR Part 11 regulation, and can streamline data access during audits required to maintain GMP manufacturing status.

“We’re serious about ensuring data security and integrity,” Moursund says. “All data produced by the instrument are encrypted, and users are never permitted to delete sampling records for any reason.

“And we’re just as serious about making the new 3400+ model even more user-friendly. We designed it to be light so it’s easier to carry from location to location. Plus, the 10-inch touchscreen is highly sensitive, so data entry can be trouble-free – even when users are double-gloved.

“To help simplify cleanroom monitoring for FDA and GMP compliance,” he says, “we’ve not only put a lot of valuable timesaving features into the box, but we’ve also made the box itself easier to use, carry and clean.”

FAST, ACCURATE, AND QUANTITATIVE VALUES

Accurately measuring trace or residual pesticides in agricultural materials and trace levels of regulated chemicals in tap water

The JMS-TQ4000GC Triple-Quadrupole Mass Spectrometer accurately measures trace or residual pesticides in agricultural materials and trace levels of regulated chemicals in tap water, and simplifies quantitative analysis of persistent environmental pollutants such as dioxins and PCBs. It achieves the fastest selected reaction monitoring switching speed in the industry at 1,000 channels per second. Chemists can analyze multiple target compounds with high accuracy.

The JMS-TQ4000GC offers three distinct technologies for high-speed analysis: ion accumulation, the short cell, and a fast GC technique. The short collision cell accumulates ions and ejects them in rapid pulses; the noise level of the signal is reduced by synchronizing the timing between pulsed ion ejection and signal acquisition, facilitating high-sensitivity analysis. A short and narrow capillary column with a rapid oven temperature ramp then allows the TQ4000GC to expedite routine analysis by reducing the time needed for measurements. The short collision cell technology provides enough high-speed transitions for fast GC measurement without any sensitivity loss.

Easier and faster data analysis

With an easy-to-read layout and simple operation, the TQ4000GC data analysis software “Escrime™” was developed for simultaneous multi-component analysis. Chromatograms are arranged in a vertical column, making it easy to compare samples. Combined with the compound “slideshow” function, the Escrime software makes it easy for chemists to confirm all
samples and components.

A wide range of organic analyses

In addition to the standard electron ionization source, the JMSTQ4000GC also supports optional chemical ionization and photoionization sources, enabling easy acquisition of molecular weight information. The system is also not limited to just GCMS. It can conduct two types of direct probe experiments: direct insertion probe for insoluble compounds and direct exposure probe for high-boiling-point and labile compounds.

EVOLUTIONS IN ANALYTICAL SAMPLE PREPARATION

Evolutions in Analytical Sample Preparation

Chemical compatibility, binding, extractables and column life are critical in HPLC sample preparation. The quality of the membrane used to filter your samples has a direct effect on these factors, so selecting the right membrane is paramount to producing consistent, reliable results.

Water-wettable PTFE (wwPTFE) is a hydrophilic, chemically inert membrane designed specifically for chromatography. Developed as an allpurpose membrane for aqueous, acidic, basic, non-aggressive organic, and aggressive organic solutions, the wwPTFE membrane offers minimal protein binding and low levels of UV-absorbing extractables.

wwPTFE is offered in syringe filters, centrifugal devices, multi-well filter plates, and standalone membrane discs. Many of these devices incorporate a glass-fibre prefilter for the efficient filtration of high-particle-laden samples.

Working in a more collaborative way with our customers is something that I look forward to continuing in the future.

What is your prediction for the future or analytical instrumentation?

Analytical instrumentation is becoming faster, smaller, and more sensitive, which places even greater emphasis on properly filtering samples. Clean and retentive filters are essential when it comes to keeping instruments running smoothly. How: by removing all particulates that could block columns and tubing while ensuring consistent baselines and low backgrounds for optimal detection of analytes.


NEXION® 5000 MULTIQUADRUPOLE ICP-MS

The industry’s first four-quadrupole ICP-MS, delivering superior interference removal, excellent stability, and unmatched matrix tolerance

PerkinElmer’s NexION® 5000 Multi-Quadrupole ICP-MS is a four-quadrupole instrument designed to remove the most complex interferences and address the most challenging applications in trace elemental testing. It takes ICP-MS performance beyond high-resolution ICP-MS and traditional triple-quadrupole technology to deliver exceptionally low partper-trillion (ppt) background equivalent concentrations (BECs).

Unlike triple-quadrupole systems, the NexION 5000 ICPMS delivers four stages of mass separation: a clean, focused ion beam of the mass of interest is introduced into the ion optics, enabling control of the fate of interferences as early in the process as the quadrupole ion deflector (Q0), where the ion beam is shaped and then directed to Q1 (first transmission analyzer quadrupole ). Mass separation takes place here. The on-mass ions then enter the quadrupole universal cell (Q2), where dynamic bandpass tuning controls the reaction and eliminates reaction byproducts before they have a chance to form new interferences. The resulting ions are mass separated in Q3 (second transmission analyzer quadrupole) before detection. This unique design makes the NexION 5000 the only ICP-MS to not only offer fine control over what enters the cell but also the reaction within the cell, delivering superior interference removal.

Plus, the novel second-generation triple cone interface with patent-pending OmniRing™ technology was developed with both sensitivity and stability in mind, providing a seamless solution for reducing space charge effects.

The combination of these and other tried-and-tested proprietary technologies allows the NexION 5000 ICPMS to deliver less than 1 ppt BECs (even under hot plasma conditions) for alkaline and alkaline earth elements, as well as ppt BECs for non-metals, such as sulfur, silicon and phosphorus. This is key for ultra-trace elemental analyses in challenging application areas. For example, instrumentation used in semiconductor device fabrication needs to be capable of detecting the lowest possible concentrations to reduce field failures of semiconductor products. And, in the health sector, especially biomonitoring, inaccurate results can make a great difference regarding patient diagnosis and treatment.

PerkinElmer’s NexION 5000 Multi-Quadrupole ICP-MS delivers performance to the power of four.

THIS MALS DETECTOR LOVES DETAILS

Green light in multi-angle light scattering for highly sensitive measurement of molecular weight and size in GPC, HPLC, and UHPLC

Do you need to determine the properties of polymers or investigate proteins and their aggregates in their native conformations? The LenS3 Multi-Angle Light Scattering (MALS) detector is the first in history to facilitate direct measurement of molecules down to 2 nm in size (the radius of gyration).

This MALS detector, which combines the advantages of low-angle (LALS), high-angle (HALS) and right-angle scattering of light (RALS), exerts its full range of capabilities in polymer and protein analytics. It achieves a high signal intensity by using a green laser and an extended light path. At the same time, the flow cell’s construction eliminates noise from stray light and thus ensures high S/N – even with lowconcentration solutions. The patented design enables a new calculation methodology of size without complex extrapolation procedure.

The direct measurement of molecular weight and molecular radius for synthetic polymers, polysaccharides, proteins, and other biopolymers is thus simplified.

TED-GC/MS SYSTEM FOR MICROPLASTICS

Thermal Extraction and Desorption (TED)-GC/MS combines large sample pyrolysis with Thermal Desorption (TD) and GC/MS for accurate microplastic analysis

Automated pyrolysis is performed in a thermogravimetric analyzer (TGA), and volatile polymer decomposition products are concentrated by solid-phase extraction in a reusable trap. The trap is subsequently transferred to the thermal desorber for TD GC/MS determination. The TGA and TD-GC/MS processes are effectively decoupled, preventing non-volatile pyrolysis residues from reaching and contaminating the GC/ MS. Automated, uninterrupted TED-GC/MS analysis of large sample batches can be performed.

Sample sizes up to 100 mg enable representative sampling and simplify handling - even of soil, silt or compost samples, which only need to be dried and homogenized before analysis. In combination with fractionated filtration, size fractions in air and water samples, including road run-off and drinking water, are easily determined without further sample preparation.

Polymers are determined via specific pyrolysis marker compounds. Identification is comprehensive and verifiable, and quantification can be performed using internal or external standards. Combining large sample capacity, pyrolysis residue elimination, solid phase concentration and TD-GC/MS results in significantly improved limits of quantitation for polymers in complex environmental samples. The GERSTEL ChromIdent Pyro-Edition software enables simple and efficient data processing, even for complex mixtures and matrices. As an added benefit, the TGA curve allows monitoring of replicate sample homogeneity for QC purposes.

TED-GC/MS was invented at the Bundesanstalt für Materialforschung und-prüfung (BAM) in Berlin. The BAM is the leading scientific and technical federal German institute for materials research and testing. Their partnership with GERSTEL led to the development of an integrated and patented interface, and the automated analysis system. An ISO standard based on TED-GC/MS and pyrolysis-GC/ MS is under development in ISO TC61 (Plastics) for general ways to determine microplastics.
