Fast sampling of emissions from products and materials. The Micro-Chamber/Thermal Extractor™ (µ-CTE™) is a versatile and compact unit with up to six small cylindrical chambers that enables the sampling of chemicals released from products or materials. Released volatile and semi-volatile organic compounds (VOCs and SVOCs) are collected onto sorbent tubes for analysis by TD–GC–MS. The capability of the Micro-Chamber/The…
HiSorb™ is an innovative, labour-saving sampling system for the analysis of volatile and semi-volatile organic compounds (VOCs and SVOCs) in liquids and solids by TD–GC–MS.
A breakthrough in sample automation and concentration for GC–MS
High-throughput platform for routine, high-sensitivity analysis using high-capacity sorptive extraction (HiSorb), headspace- and SPME-based workflows
Versatile platform for high-sensitivity routine analysis using headspace-, SPME-, thermal desorption- and HiSorb™ high-capacity sorptive extraction-based workflows
ACTI-VOC™ is a robust low-flow pump for sampling vapour-phase organic compounds (VOCs) onto sorbent tubes for subsequent analysis by thermal desorption (TD). Being lightweight, easy-to-use and intrinsically safe, ACTI-VOC is ideal for personal monitoring and a wide range of other air and gas sampling applications. Optimised for thermal desorption tubes Unlike other personal monitoring pumps on the market, ACTI-VOC is optimised…
On-line sampling module for the UNITY-xr™ thermal desorber
Thermal desorption sorbent sampling tubes for air sampling. Backed up by fast and friendly service, Markes’ tubes provide optimum sampling and analytical performance. Our range includes everything from cost-effective packages of industry-standard tubes to the last word in sorbent tube innovation. Features: Our industry-standard (3½-inch (89 mm) long x ¼-inch (6.4 mm) o.d.) sorbent tubes are available in stainless stee…
Multi-tube sequential sampler. The MTS-32™ is a compact, portable sampler for the unattended sequential sampling of air onto a series of sorbent tubes. Constant-flow pump technology ensures that the same volume of air is collected onto each tube.The MTS-32 is ideal for analysts needing monitor the concentrations of organic vapours in air as they fluctuate over extended time periods.Features: Sequentially samples on up to…
Accurate and repeatable gas flow measurement. Accurate and repeatable gas flow measurement is fundamental to obtaining good results from your thermal desorption-gas chromatograph. The traditional bubble flowmeter, relying as it does on the reaction time of the operator, is a potential source of error.The digital flowmeter eliminates this source of error and makes gas flow easement easier and more accurate. The flowmeter allow…
Water removal device for use with UNITY™–Air Server-xr™ thermal desorption systems.
Markes’ stainless sorbent tubes are available in two sizes: 3.5” x ¼” (industry-standard), and 4.5” x 6mm (DAAMS). Industry-standard tubes are compatible with Markes, PerkinElmer, Shimadzu, Dani, CDS and Gerstel 3.5+ thermal desorption (TD) systems.
