The Aquatek 100 Waters-only Autosampler is now available from Teledyne Tekmar. It is a purge and trap autosampler that automates the sample preparation steps for the analysis of liquid samples using a fixed volume sample loop filled using a pressurisation gas.

Two independent volume programmable internal standards are then added to the sample and the entire aliquot is transferred to the Purge and Trap for compound concentration and subsequent separation and detection using GC/GC-MS. Autoblanking allows customers to use more vial positions for actual samples rather than required quality control as the blanks can be generated from the built-in water reservoir and the standard vial cooling system allows samples to be chilled to 10°C prior to analysis.
