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.

Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. To ensure the safety of operatives in the screening building/area of waste water treatment works an H2S analyzer has been installed in the main building to complement the protection provided by individual monitors. Chromatographic measurements show that other sulfurous compounds including Methylmercaptans are present in the air in addition to H2S.

Durable, reliable analysis for black liquor. Black liquor is a difficult substance to work with. It’s caustic, it’s toxic, and it emits poisonous gases such as hydrogen sulfide. But the efficient use of black liquor is critical to the profitable operation of any pulp and paper mill. In order to use black liquor efficiently, you need to test it for solids. Make sure your solids analyzer is up to the task.
