Nylon is a hydrophilic membrane that is the industry standard for general use aqueous samples

High-performance sterile and non-sterile filtration for mass spectrometry, chromatography, media preparation, cell culture, and protein purification

Accurate, reproducible data depends upon proper HPLC column performance.

High sample throughput (up to 150 mL) and fast flowrates (up to 245 mL/min) reduce time and effort required to filter a wide array of sample volumes

In many laboratories, laboratory managers and technicians need to ensure their instruments are performing optimally around the clock.

This Technical Guide can be used for reviewing filtration requirements and performance criteria with new lab personnel.

The Analytical Sample Preparation ebook was created as a tool to learn more about the benefits of sample and mobile phase filtration

Each part of this eNewsletter series has explored a different aspect of Chromatography sample preparation

There are many reasons to use a Pall syringe filter?

Filtration can pose potential drawbacks, one of which being unwanted drug adsorption by the filter, causing out-of-specification (OOS) results

The purpose of the test was to see how many injections a column could take before becoming blocked due to particulate load and requiring replacement.

As HPLC and other analytical methods are sensitive and serve as qualitative and quantitative techniques, the filter material you choose is important

Of the four common causes for HPLC column failure (plugging, voids, adsorbed sample, and chemical attack), plugging is the most frequently encountered

When choosing the correct filter for the job, there are four different points that an analytical chemist must consider

Learn more about how choosing the right filter can reduce column blocking, reduce backpressure and help produce more reliable results

Sample preparation and clean-up is crucial for ensuring reliable, repeatable results and extending the chromatography column’s useful life.
