A research and development team in Europe uses the TECA Model AHP-1200CPV Cold Plate with a TECA Model TC-1 Tube Chiller attached.
Their process is proprietary but involves optical material and measurements. The TC-1 Tube Chiller is designed to heat or cool fluid without introducing contaminants to the fluid.
The fluid flows through the flexible tubing (various tubing diameters are possible) within the plate surface.
Stock thermostated sample tray supplied with mass spectrometer holds water samples at above ambient temperature. This leads to evaporation and condensation within the sample vials, and problems of gas transfer through sample needle to mass spectrometer (liquid condensation blocks gas flow through capillary tube).
USF Geology Stable Isotope Laboratory installed a second auto-sampler with a TECA AHP-1200CPV cold plate to keep samples at precisely controlled temperatures to prevent condensation and evaporation of the sample within the vials, and maintains the thermal stability required for isotope ratio mass spectrometry of water samples analyzed by equilibration method.
