The Industrialisation of the XIX Century has seen drastic increase of all means of transportation. The invention of the automobile brought relief in the life of people, but nowadays, those cars, lorries and buses are responsible for many airborne pollutions and impact not only in megapoles but also in rural areas. The need of cleaner cars has brought new tigher regulations and the need for careful monitoring of automotive emissions. Our photoacoustic photometer are participating in that effort to curbe the pollution level down but providing accurate measurement of all molecules of interest including, N2O, NOx, SOx, H2S, Formaldheyde, CO, CO2…

The Series 8900 Hydrogen Sulfide and Carbon Disulfide Analyzer provides direct measurement of H2S and CS2 in ambient air. This instrument is utilized for continuous emission monitoring. The Series 8900 H2S and CS2 Analyzer employs a Photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is carried to the pre-cut column. Backflush is timed so that only the H2S, CS2, and other similar components are eluted to the analytical column. Contaminants on the pre-cut column are backflushed to vent. H2S and CS2 are separated from potentially interfering components on the analytical column and elute to the detector for analysis.
