  • Residual Gas Analysis

    Residual Gas Analysis is a general term for the analysis of gas and vapour species in vacuum chambers and vacuum processes. The Hiden RGA series quadrupole mass spectrometers provide for routine, fast, wide dynamic range residual gas analysis, measuring the partial pressures of the species that are critical to vacuum quality and process requirements. Applications include: vacuum chamber leak detection vacuum quality measurement and monitoring virtual leak detection outgassing studies bakeout cycle/vacuum pump down monitoring

    Measurement solution for breathing gas analysis

    The quality of compressed breathing gases for aircraft, diving and marine has very tight limits imposed by bodies such as NATO and national bodies such as MOD. The test requirements are for contaminants such as CO, CO2, Total VOC, CFCs and halogenated hydrocarbons, as well as H2O and O2 content.

    Gas analysis & monitoring system for greenhouse gases analysis

    The rising levels of manmade greenhouse gases (GHGs) in the atmosphere and their resulting impact on climate is now one of the single biggest technological and environmental challenges facing the world. This makes intensified monitoring of these gases more critical than ever in order to better quantify the role of the numerous natural and manmade sources, sinks and buffers involved in the cycles of GHGs. It also enables us to objectively audit GHG fluxes at the factory, city, country and continental level. Such objective auditing is ultimately essential to facilitate effective enforcement and compliance with any regulations, laws, treaties and trading agreements based on GHG metrics such as carbon footprints.

    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).

  • Fermentation Off-Gas Analysis

    In pilot plant and production scale fermentors, information relating to yield of product is of high importance. Hiden's gas analysers are configured with a multiport Off-Gas analysis manifold enabling simultaneous sampling from multiple fermentors. Data is used for the calculation of the respiratory quotient, carbon production rate and oxygen uptake rate. The Off-Gas measurement provides the respiratory quotient in a time and space averaged form and with good response time. By comparison data from multiple dissolved species probes are more specific and can provide information about stirring efficiency, aeration and feed distribution within the fermentor. Dissolved gas measurements have the advantage of giving direct information on gas uptake and for dissolved output rates. Hiden Analyticaloffers systems with either Off-Gas or dissolved species inlets or both.

    NAPL Fingerprinting Analysis

    Sitelab's mobile laboratory was used by a client at a former oil refinery in Kansas and at a large tank farm in Massachusetts. The UVF data was used to delineate and map subsurface plumes of NAPL. Oil samples were collected from monitoring wells and analyzed for their GRO/DRO or VPH/EPH content.

    Gas analysis & monitoring system for gas generation

    The gas generators for calibration based on the use of “Method of Permeation Tubes.”. The permeation tubes are sealed capsules containing a small amount of the component that is in contact with a permeable membrane stable. The permeation through the membrane produces a vapor of the compound of the component of small quantity, very stable as a stream in time. This permeate stream by mixing with a dilution gas controlled and precise (for example nitrogen) creates a mixture in track at the desired concentration. The flow of the permeate is measured metrically through severe weight loss of the tube thus ensuring a standard high precision.

    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 gas purity

    The purity of a gas is an indication of the amount of other gases contained in it. A high purity refers to a low amount of other gases. High purity gas are considered to be of better quality and are generally more expensive. The purity of the gas can be expressed as a percentage or as a decimal fraction. Applications for checking the purity of the gases across different industrial sectors by air separation plants, cryogenic facilities, the quality control of industrial gases to the steel mills, etc.

    Gas analysis & monitoring system for dust

    Particulate matter, suspended particulate matter, atmospheric dust, particulate matter, total suspended particulate (TSP), are terms that commonly identify the group of substances suspended in the air (fibers, carbon particles, metals, silica, polluting liquid or solid). Particulate matter is the pollutant that is now considered the greatest impact in urban areas, and is composed of all those solid and liquid particles dispersed in the atmosphere, with a diameter ranging from a few nanometers to 500 microns and above (ie billionths of a meter to half a millimeter).

    Gas analysis & monitoring system for emission monitoring

    From the environmental point of view, an issue is any solid, liquid or gaseous substance introduced into the atmosphere that can cause air pollution. Given the wide variety of substances present in the atmosphere, have been proposed several methods of classification: Primary pollutants can be of gaseous or particulate.
