HPR-40 DSA Membrane Inlet Mass Spectrometers for Dissolved Species Analysis

Membrane Inlet MS - Applications water analysis environmental monitoring fermentation process analysis Membrane Inlet Mass Spectrometry (MIMS) enables analyses of dissolved gases and volatile compounds from bulk samples. Applications: XXWater analysis in Estuary, River or Reservoir (Denitrification) Membrane Inlet Mass Spectrometry (MIMS) XXSoil core analysis XXFermentation process analysis Gas/Vapour Molecule XXGroundwater contamination studies Polydimethylsiloxane Membrane (gas permeable) Partitioning XXMethane production control XXMicrobiological/Enzyme activity studies XXEnvironmental monitoring...

Example Data PPT Level Detection of Volatiles in Water DMS signal intensity counts/sec (c/s) The HPR-40 DSA was used to detect trace amounts of CH3SCH3 (Dimethylsulfide DMS) in ocean water. DMS is a naturally occurring substance produced from micro-organisms and related to global 40000 (HAL 101/3F, PIC mode) 40nML 35000 climate change and regulation. -1 25000 -----DMS The amounts which were detected in this application go down to 60 ppt Diluteamu peak at 62 20000 4nML (parts per trillion), which corresponds to dilute concentrations of DMS 15000 1nML of less than 1 nML-1. 10000 -1 The diagrams...

Inlet options FLOW-THROUGH PROBE CUVETTE CELL ENZYME KINETICS PROBE The Flow-through Probe is directly mounted on the MS with two ports to allow flow from an external reservoir. It is used for a wide range of dynamic applications. The Cuvette Cell is designed to allow temperature control and illumination of a liquid sample – e.g. for algae studies. The Enzyme Kinetics Probe was specifically developed to be submerged in enzyme containing samples. All wetted parts are made of glass to avoid sample contamination and side reactions.
