Working Principle of Gas Chromatograph Different forms of Gas Chromatography Gas-solid chromatography In the process of gas-solid chromatography, the mixture is separated via the adsorption process. Compared to GLC, it is less frequently employed for the separation of low molecular gases like CO2, H2, H2S2, and CS2. Gas-liquid chromatography In the process of gas-liquid chromatography, …
Why are Lambda sensors fitted? What does the lambda sensor do? How does the lambda sensor work? Zirconia Binary type Titania Type ZFAS-U Type (Air/Fuel Sensor) How to test Lambda sensors? Procedure for testing the lambda sensor’s functionality Ground for the oxygen sensor heater (white); Positive power oxygen sensor heater (white); Lambda probe signal (often …
IR gas Detector Infrared Gas Analyzer Spectrum Infrared energy was employed by spectrum IR analyzers to analyze gases while only using a small percentage of the entire electromagnetic spectrum. For instance, the gas CH4 exhibits a significant absorption peak at 3.4 microns and an absorption wave length of 3.4 microns. Gases such as CO, CO2, …
What is meant by Conductivity? How is conductivity measured? Units of Conductivity Conductivity Meter Cell constant x conductance = Conductivity. Note that the current source is changed to make the measured potential (V) and reference potential (Er) identical (about 200 mV apart). Conductivity Measurement principles Conductive principle A cell having two metal or …
