Non-invasive tube-based biological monitoring

On-line sampling module for the UNITY-xr™ thermal desorber

Robust and easy-to-use soil gas sampler. The VOC-Mole is a stainless steel assembly that is inserted into the ground, allowing soil gas to be sampled onto a sorbent tube, for analysis by thermal desorption (TD)–GC–MS.The VOC-Mole is simple to use and easy to transport, and perfect for any analyst wishing to monitor levels of volatile organic compounds in soil.Features: Organic pollutants pass through holes in the hollow t…

Grab-sampler for air sampling. Easy-VOC is a hand-held device that facilitates the rapid ‘grab’ sample collection of small volumes (<500 mL) of air directly onto sorbent tubes without the need for calibrated pumps.Sorbent tubes attach to the end of the Easy-VOC and air/gas is drawn directly onto the tube. Easy-VOC regulates the flow rate independent of the force used to pull the air through.Grab sampling involves collecting v…

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…

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.

MARGA (Monitor for AeRosols and Gases in ambient Air) has been developed by Metrohm Applikon in cooperation with the Energy Research Centre of the Netherlands. The instrument offers a new approach in which gases and aerosols sampled from the same air mass are separated from each other by selectively dissolving them in water. The resulting solutions are then analysed using ion chromatography with conductivity detection. Separat…

The 944 Professional UV/VIS Detector Vario is the intelligent UV/VIS detector from Metrohm. It permits a secure and reliable quantification of substances active in the ultraviolet or visible range. Detection takes place via a Diode Array. The 944 Professional UV/VIS Detector Vario enables reliable and accurate quantification of substances that absorb light in the ultraviolet or visible range. The instrument is operated by t…
