multi-gas analyzer ETG 4500 EIMS is the first ETG instrument to use EIMS technology, which allows for highly accurate monitoring (ppb level) of trace amounts of ammonia (NH3), hydrogen chloride (HCL), hydrogen fluoride (HF), acids, NOx, Cl2, acetone, VOCs, and others in the air.ambient air. Compact design, high sensitivity, fast response and ability to separate isomeric compounds, Ion Mobility Spectrometry (IMS ) is a powerful molecular analytical spectrometry technique based on ionic interactions in a homogeneous electric field that allows accurate and reliable measurements in many industries, especially where air quality is a critical factor. This analyzer uses an improved version of this technology: Enhanced Ion Mobility Spectrometry. Advantages compared to the old IMS: No radioactive source Flow control with MFC Pressure measurement No need for a scrubber Spectrum saving 2d spectra Mobility spectrum (not time spectrum) Possibility of setting up VOC monitoring Applications: Airborne contamination of cleanrooms Semiconductor process application Electronic industry Food quality control Gas odor application Monitoring of the scrubber
