Is H2S a suitable process indicator for odour abatement performance of sewer odours?
Odour abatement units are typically designed and maintained on H2S concentrations, but operational failures are reported in terms of overall odour removal, suggesting a wide range of malodorous compounds emitted from sewers that may not be efficiently removed by existing odour abatement processes. Towards providing greater insight into this issue, several activated carbon filters and biofilters ...

GC-MS analysis of phthalate esters using hydrogen carrier gas
From July 22nd 2019, RoHS3 (directive 2015/863) added an update to the list of Phthalate esters included in the list of regulated substances. GC-MS is now the standard method for analysis of Phthalate esters. Abstract As helium increases in price and availability begins to affect supply of gas to laboratories, alternative carrier gases for GC-MS analysis are increasingly being adopted. An ...

Solutions to the world Helium shortage with the H2 generator for GC and GCMS carrier gas Application Notes 15 December 2013
Why change from Helium ? Gas Chromatography can use alternative gases and this is where F-DGSi can help. Helium has dominated gas chromatography due to the level comparison between it, hydrogen and nitrogen. Nitrogen is less efficient than helium and hydrogen has been avoided in the past due to safety concerns with hydrogen cylinders. These concerns are based on hydrogen cylinders being fairly ...

Silent sentinel role for static gas analyser at United Utilities
Biogas produced by the United Utilities anaerobic digestion sludge plant at Lancaster (Stodday) waste water-treatment runs a brand new 525kW combined heat and power (CHP) engine generating electricity and now operating 24/7. It joins an existing 325kW engine already in service for three years. In addition to biogas from the Stodday mesophilic anaerobic digester, a new enzymic hydrolyser increases ...
