Designed for analysis of gases, vapours and VOCs in liquids
Hiden Analytical offers class-leading gas monitoring solutions designed to obtain and quantify complex species in liquid samples. Our ultra-precision HPR-40 DSA is a compact membrane inlet mass spectrometer (MIMS) and a versatile instrument suited to dissolved and evolved species analysis. With a wide selection of compatible differential electrochemical mass spectrometry (DEMS) cells available, the HPR-40 DSA can also be tailored for precise real-time electrochemical analyses.
Membrane inlet mass spectrometry is a tried-and-trusted technique for resolving dissolved gas species from liquid samples. It is routinely employed in environmental monitoring applications such as the analysis of groundwater to quantify low-level pollutants, or recreational applications where disinfectant by-products (DBPs) could be harmful to the health and wellbeing of swimmers.
The Hiden HPR-40 DSA can monitor gas species in liquids at the sub-parts per billion (ppb) level with a standard mass range of 200 amu for dissolved species. Exceptionally precise, this bench-top membrane inlet mass spectrometer is uniquely suited to gas monitoring applications where extremely low levels of concentration monitoring are critical to success.
