For more information visit https://markes.com/shop/products/tf-spme TF-SPME (thin-film solid-phase microextraction) is a novel sampling approach for ultra-trace-level analysis of VOCs and SVOCs using sorptive extraction. TF-SPME uses a carbon mesh strip impregnated with a sorptive phase with 100× greater volume than a typical ...
Thermal Extraction of Liquids and Solids using Micro-vials to perform the GERSTEL Automated Tube Exchange Technique Automated liquid injection and introduction of analytes from dirty matrix samples into a gas chromatograph with a mass spectrometer detector is shown using the GERSTEL MultiPurpose Sampler (MPS) and Thermal Desorption Unit (TDU). Many types of samples cam be analyzed with this ...

Automated headspace injection into a gas chromatograph with a mass spectrometer detector is shown using the GERSTEL Dual Head Single Rail MultiPurpose Sampler (DHSR MPS). The use of this sampler adds capabilities such as internal standard addition, dilution, and derivatization. This sampler can also be used with techniques, such as solid phase extraction (SPE), dispersive solid phase extraction, ...

The GERSTEL IsoTube sampling platform features 3 IsoTube Trays with a sample capacity of 72 IsoTubes, 1 auxiliary port tray, and 32 auxiliary positions for connecting gas standards, flow cells, and IsoJars. A flow cell is used for injecting the sample to the gas chromatograph that does not have a gas sample loop. IsoJars are large headspace jars used to collect drilling core and water samples for ...
