    Medical Gas Analysis for Process Industry

    USP37 Medical Gas requires a specific, selective and positive identification test using a paramagnetic signal. Regular analysis of medical gas is required to ensure that the oxygen concentration is NLT 99.0% volume. Following the appropriate United States Pharmacopeia standards, in this case specifically USP37, requires an analyzer which uses a paramagnetic based technology.  The Systech Illinois Paramagnetic Oxgyen Analyzer PM700 is perfectly suited for this medical gas analysis application.

    Gas analysis & monitoring system for biogas analysis

    “Biogas” means a mixture of various types of gas (mostly methane) produced by bacterial fermentation in anaerobic conditions(absence of oxygen) of organic residues from waste, decaying plant, carcasses in putrescence. The analyzers of biogas by Infrared cells carry out the continuous analysis of CH4, O2, CO2, H2S and NH3. The whole process sees the decomposition of organic material by some types of bacteria, producing carbon dioxide, molecular hydrogen and methane(methane conversion of organic compounds).

  • TOC Correlation to BOD or COD

    Challenge: Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) are traditional parameters analyzed in the laboratory to determine organic matter in water and wastewater. Wastewater facility operators need to have constant data to monitor their discharges and optimize treatment processes (biological treatment, chemical dosing, etc). The requirements of BOD and COD analysis prevent them from being implemented as control parameters, however. The BOD five-day analysis time requirement does not allow an operator to use the data for process optimization and. although COD requires less time than the BOD, its analysis includes the use of hazardous chemicals and has no constant analysis capability.
