  • Integrated real-time gas analysis solution for moisture in ammonia industry

    The highest purity of ammonia is a requisite chemical gas for the production of flat panel displays and for LEDs; the purity issue is one of achieving moisture levels at the ppb level, as in the case of epitaxial reactor applications. However, the problem requiring a solution derives in part from the fact that the FTIR spectra for moisture and ammonia overlap to the degree that the moisture peaks are masked by the ammonia peaks at high concentrations. As a result the moisture peaks cannot be used for quantitative concentration measurements.

  • Filtration for Flue Gas Analysis and CEMS

    Three Steps of CEMS: 1st Step: Gas Sampling 2nd Step: Gas conditioning and treatment 3rd Step: Measurement/Calibration In first step, the function is to get sample gas and forward to 2nd step for treatment. During this step, it cannot block the probes and cannot result condensation of moisture. So a filter online back flushing should be equipped in this part. The filters to be used: 1, Filter is used to ensure the stability of system and reduce the maintenance 2, Filtration Grade: usually 2 or 3 micron 3, Temp. is around 0-180 deg C 4, Back flushing gas is heated, impulse flushing 5, Filter Material: Titanium Sintered, SS316L Sintered, PTFE sintered, Ceramic Membrane and so on 2nd Step Gas Treatment: #11;The coarse filters and the liquid particle filters The coarse and fine cartridge can filter the small particles in the gas and acid aerosol things to better protect the instruments. The micron can be 0.1micron, filtration rate can be up to 99.99%, two layers can be 99.9999%

  • Integrated real-time gas analysis solution for semi-gases industry

    CIC Photonics first applied its IRGAS technology to semi-gases when a major semiconductor equipment manufacturer, Applied Materials, requested a demo of its capability to monitor gas quality for epitaxial reactor applications; that was in year 2000. The IRGAS System met all of the technical requirements, which included ppb sensitivity for moisture as an impurity, gas cell chemical resistance to both acid and basic semi-gases, and fast concentration tracking time response.

  • Integrated real-time gas analysis solution for electronic specialty gases industry

    The company’s entry into the electronic specialty gas market originated in 1994-95 as a consequence of the semiconductor industry’s demand for increasingly higher purity gases from the major gas producers. The issue was then and remains today to be primarily moisture impurity levels in the cleaning, etching, and treatment gases used in wafer production. In that earlier period when common wafer sizes were 6” and 12”, the semi industry required moisture concentrations to be 250 to 500 ppb or better; with each year after that the industry tightened its requirements such that today the moisture specifications are 1 to 5 ppb or better.

    Measurement of methane, methanol and ethanol for the biomass monitoring for biofuels.

    The Series 8900 provides direct measurement of methane, methanol, and ethanol for the biofuel industry. The Series 8900 GC employs a flame ionization detector (FID). The methane, methanol, and ethanol in the gas sample are physically separated using proprietary GC columns. A dual-column configuration with timed backflush to vent is used to strip off moisture and heavier gases. At sample injection, a fixed volume of sample is carried through the pre-cut column. The backflush is timed so that primarily the MME and other similar compounds continue on to the analytical column. Contaminants are then backflushed to vent. Methane, methanol, and ethanol are separated from potentially interfering components on the analytical column and elute to the detector for analysis.
