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…

The helium leak detector is a portable, highly sensitive instrument designed to detect helium carrier gas leaks in thermal desorption and GC systems. Gas leaks are indicated with both an indicator lamp display and an audible alarm. The long, flexible probe makes it convenient to detect small and hard-to-reach gas leaks. Using the detector for gases other than helium is easily achieved by changing the polarity setting. The det…

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…

Package for monitoring benzene and other VOCs at refinery perimeters

Water removal device for use with UNITY™–Air Server-xr™ thermal desorption systems.

The POD Sampler (POcket Diffusive Sampler) is a radial diffusive sampler for volatile organic compounds (VOCs), compatible with analysis by thermal desorption.

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.

Reversible Flip Seal—Same Cost, Twice the Lifetime New reversible Flip Seal inlet seals from Restek last twice as long as other inlet seals. Simply use—flip—then use again. The reversible design doubles the number of analyses you get per seal. •Same easy sealing as Dual Vespel® Ring Inlet Seals—no extra washer needed. •Lower leak rate than OEM metal seals. •Maximum transfer of analytes to column, due to highly inert gold or Si…

• Optimized deactivation produces maximum response when analyzing trace levels of acetylene, methyl acetylene, and propadiene. • Stable response factors make this column ideal for process-type applications where recalibration must be minimized. • High loadability reduces peak tailing and improves separations. • Extended temperature range up to 250 °C for fast elution of high molecular weight (HMW) hydrocarbons and accelerated…
