This Application Note describes the fast and highly sensitive detection of trace-level aroma compounds in the headspace gas above fresh strawberries.

This study shows highly sensitive detection of residual fumigants in seeds and spices

This application note demonstrates the quantitative analysis of ODS and halogenated GHGs without use of cryogen

Local authorities need to invest heavily to ensure drinking water is safe and palatable

The challenge of monitoring off-odours in fish

Haloanisoles create a musty/moldy off-aroma in wines that is rejected by consumers, causing important economic losses for the wine industry

HiSorb high-capacity sorptive extraction probes provide a highly sensitive, robust and fully automatable means of extracting organoleptic compounds.

This study demonstrates how sorptive extraction using high-capacity HiSorb probes was used to extract aroma compounds spanning a wide volatility range

A fully automated workflow – from sample extraction to data analysis – was used for the flavour profiling of four different brands of hard seltzer.

Chemical warfare agents (CWAs) and their respective simulants were analysed using Markes’ tube-based systems.

Identification, measurement and characterisation of volatile organic compounds using by thermal desorption–GC-MS/sulfur chemiluminescence detection

Markes’ thermal desorption tubes with a variety of sorbent packings for all TD applications deliver optimum results time after time.

UNITY-xr™ is an industry-leading analytical TD instrument that provides good performance for VOCs and SVOCs collected onto 3½-inch sorbent tubes

Thermal desorption sorbent tubes that allow up to 500 L of air to be sampled for the detection and analysis of PFAS compounds

TD100-xr is a multi-tube TD for high-throughput automated analysis.

A radial diffusive sampler (for analysis by thermal desorption). A large diffusive surface area for adsorption and a short diffusive pathway

A major step forward in sample preparation technology. HiSorb probes sorptively extract VOCs/SVOCs from a range of sample types

A powerful leap in analytical technology – and a world’s first for thermal desorption instruments

Markes’ industry-standard-size TD tubes (3½″ × ¼″ o.d.) are available in three materials: stainless steel, inert-coated stainless steel and glass.
