GeoTech G100 Co2 Analyser with Hygroclip 2 Advanced Humidity Sensor Lab

Manufacturer: Hiden Isochema Model: IGAsorp Dynamic Vapor Sorption Analyzer S/N: IG-SA-069 Descripti (more)on: IGAsorp Dynamic Vapor Sorption Analyzer is a fully automated compact benchtop DVS analyzer, for fast and accurate sorption measurements using the dynamic flow technique for water and organic solvents. Measured vapor uptake isotherms and kinetics are used to characterize, test and evaluate materials in precisely defined environmental conditions. An ultra-sensitive microbalance measures changes in sample mass as a function of humidity and temperature. Humidity is determined by relative mixing of wet and dry gas streams, and is measured and regulated at the sample position. These factors combine to offer unrivalled performance and total baseline stability. The IGAsorp uses the unique IGA method for the determination of the sorption kinetics and equilibrium isotherms. This ensures accurate and consistent analysis with faster analysis times making the optimum use of instrument time. Hiden Isochema’s unique IGA method is applied independently to every step in a gravimetric sorption measurement. At each step, the humidity and temperature are actively regulated, with resultant changes in sample weight continuously recorded. The kinetic weight data is analyzed in real-time, and the trend toward equilibrium is predicted and displayed on screen. Equilibration criteria are applied to objectively determine the period allowed before the measurement moves on to the next pressure or temperature value. Each equilibrium point is plotted on an isotherm or isohume, and the full raw data is also recorded. The IGAsorp therefore allows consistent analysis with optimum measurement accuracy and faster overall process times.

Manufacturer: Environics-IUT Model: ENVI-Air GC-IMS-Analyzer S/N: IM0911.120011 YoM: 2012 Descripti (more)on: The ENVI-Air from Environics is a continuously operating gas analyzer designed for ultra-low level detection of either single or multi-component hazardous gases in ambient air. It will operate indoor or outdoor in the harshest environmental conditions and needs little or no maintenance. The ENVI-Air can detect hazardous gases at far lower concentrations than traditional analyzers and react in real-time. This gives the operator a longer safe response window to take corrective action.It is based on GC-IMS technology. Ion Mobility Spectrometry (IMS) is a simplified atmospheric pressure time-of-flight technique that is highly selective with low ppb to % sensitivity. The GC-IMS adds multi-component separation prior to the IMS analysis. ENVI-Air does not require the use of paper tape, pre-concentrators or chemical reagents.The ENVI-Air is an industrial solution virtually drift free and unaffected by humidity or temperature changes and will be factory calibrated for the compounds of interest for maximum accuracy and reliability. Because of the simplicity of design and limited moving parts, ENVI-Air analyzers will have the lowest maintenance and downtime of any current analyzer system. Measurable Compounds: Ammonia, Acetone, Acrylonitrile, Acetonitrile, Arsine, Benzylchlorid, Bromine, Chlorine, Chlorocyane, BTX, CMME, Ethylene Oxide, Dibutylphthalat (DMP), Dimethylsulfat, HFPO, Hydrazin, Hydrogen Chloride, Hydrogen Bromide, Hydrogen Fluoride, Hydrogen sulfid, TDI, Methyl Bromide, Isopropyl alcohol, Methyl Iodide, Nitrogen dioxide, NMP, PFIB, Phosgene, Phosphine, PGME, PGMEA, Sulfur Dioxide, Triethylamine, Vinyl Chloride.
