Gas chromatography thermal desorber UNITY-xr

Single-tube thermal desorption unit is ideal for labs with low throughput requirements or that need upgrade flexibility for tubes, canisters, and on-line automation; Air Server-xr adds three channels for automated on-line sampling Thermal desorption (TD) is a versatile preconcentration technique for gas chromatography and GC/MS that combines sample preparation, extraction, and injection into a single automated process. It is used to analyze very volatile to semi-volatile organic compounds in a variety of solid, liquid, and gaseous samples across diverse application areas. This technique is safer and more environmentally friendly than solvent extraction, easy to automate and validate, and complies with standard methods. Agilent GC and GC/MS instruments with TD systems from Markes International, including Multi-Gas versions, offer the sensitivity, flexibility, and dynamic range to meet your VOC and SVOC analysis needs. Multi-Gas enabled systems for compatibility with hydrogen, nitrogen, and helium carrier gas Hydrogen carrier gas compatibility provides cost savings over helium and allows for higher throughput due to faster chromatographic separations Quantitative sample re-collection of all split flows enables repeat analysis of critical samples, easy method validation, and overcomes the one-shot limitation of conventional TD systems Capacity of up to 100 tubes and the ability to use overlap mode provide enhanced throughput Configurations for 14-channel canister, 4-channel canister, or 3-channel on-line, with 100-tube automation available for ultimate flexibility on one TD-GC-MS system Electronic tube tagging: RFID tags for simplified chain of custody are available
