    Measurement solution for CFC abatement control via two stream FTIR system

    CFC usage in industry

    Although the use of CFCs in domestic products has been widely phased out, CFCs chemicals still prove a vital ingredient in the production of insecticides and herbicides. Such products aim to increase the rate of crop production all over the world. All aspects of such a manufacturing process in relation to environmental impact must be well controlled. The use and pre-emission removal of CFCs in the intermediary steps of the insecticide production needs to be monitored with 100% efficiency.

    Gas monitoring instruments and systems for phosgene monitoring

    Phosgene COCl2 is a colorless gas. While it has been used as a Chemical Weapon Agent (CWA) in the past, currently this poisonous gas is also an important reagent in synthesis in the pharmaceutical and chemical industries. The plants using phosgene are typically equipped with gas sensors to detect leaks in the indoor ambient air. The critical situations arise when equipment in contact with the gas at the manufacturing facilities are serviced and maintained. As phosgene is very poisonous, even small gas pockets in serviced equipment may be dangerous to maintenance personnel. Gasmet™ FTIR Gas Analyzers are ideal tools to monitor point sources of phosgene. The measurement technology has high specificity, may be operated continuously, and has a fast response time.

    Gas monitoring instruments and systems for engine emissions measurements

    The exhaust gas from combustion engines is a complex mixture of gases and particulate matter. The composition of the gas may change rapidly. Multicomponent analysis of exhaust gases can be performed with a Gasmet™ FTIR Gas Analyzer with a response time (T90) of one second. The winning combination is the result using of a small volume gas sample cell, a powerful sample pump and a fast detector with liquid nitrogen cooling. The analyzer, sampling system and computer can be assembled on a cart for use in a dynamometer laboratory, or the portable version can be used for roadside tests.

    Gas monitoring instruments and systems for semiconductor manufacturing

    In the semiconductor manufacturing industry, various perfluorinated compounds (PFCs) are used. The emissions of the PFC compounds into the ambient air are reduced by scrubbing of the exhaust gases from the process. In this process, the Gasmet™ FTIR Gas Analyzers can be used to measure the emissions into the atmosphere and also monitor the efficiency of the scrubbers. Typically monitored PFCs in the exhaust gas include carbon tetrafluoride CF4, trifluoromethane CHF3, and hexafluoroethane C2F6.

    Gas monitoring instruments and systems for process NOx measurement

    Nitric acid HNO3 is an important intermediate reagent for production of several important end products, such as fertilizers, explosives, dyestuffs/pigments, pesticides, pharmaceuticals, photographic materials, plastics, and synthetic fibers. At nitric acid manufacturing plants, the Gasmet™ FTIR Gas Analyzer can be used to measure several gaseous components from the process stream for purposes of process control. A single system can be used to measure the high levels of nitrogen monoxide NO and nitrogen dioxide NO2, as well as water vapor H2O, nitrous oxide N2O, carbon monoxide CO, carbon dioxide CO2 and ammonia NH3. The fixed installation products for these purposes are the Gasmet™ CEM II measurement system, and the Gasmet™ FCX Gas Analyzers, both of which utilize the FTIR measurement technique for simultaneous multicomponent analysis of the sample gas.

  • Analysis of aqueous solutions

    IR-Spectroscopy is not limited to gases, solid materials and pure liquids but also facilitates the measurement of solutes in aqueous media. Though, due to the strong and temperature dependent absorption of water, the usage of conventional IR-transmission and ATR accessories is not very suitable for the analysis in water. The CONFOCHECK is a dedicated FT-IR system for the fast, easy and sensitive analysis of aqueous samples. Using this system, preparing, measuring and evaluating any aqueous sample takes typically about 1 minute.

    Gas monitoring instruments and systems for stack testing according to EPA test method 320

    The United States Environmental Protection Agency (EPA) has two stack testing methods for FTIR gas analyzers. Method 320 is an FTIR method for measuring wide range of organic and inorganic pollutants. Method 321 is a specific version for measuring hydrogen chloride HCl at cement kilns producing Portland cement. These methods define a quality assurance and control processes for verifying the accuracy of the results. The requirements for analytical equipment and software are defined on 40 CFR Part 60 Appendix B Performance Specification 15. Gasmet™ Gas Analyzers and Calcmet™ software have been designed to take the requirements of the performance specification into account.
