WebThe ignition electrode and the ionisation probe are usually positioned together in the combustion chamber of the gas combustion equipment - gas-fired boilers, instantaneous water heaters, gas ranges, cookers etc. Ignition electrodes can be used as ionisation probes and vice versa. Web4 mei 2024 · Mass spectrometry (MS) plays a vital role in many aspects of our lives, from diagnosing illness and detecting food contaminants to fighting fraud. In order for a sample to be analyzed by MS, it must however, first be ionized. There are a number of ways of achieving sample ionization depending on the sample type, target analyte and desired …
Flame Ionization Detector - an overview ScienceDirect Topics
A flame ionization detector (FID) is a scientific instrument that measures analytes in a gas stream. It is frequently used as a detector in gas chromatography. The measurement of ion per unit time make this a mass sensitive instrument. Standalone FIDs can also be used in applications such as … Meer weergeven The first flame ionization detectors were developed simultaneously and independently in 1957 by McWilliam and Dewar at Imperial Chemical Industries of Australia and New Zealand (ICIANZ, see Orica history) … Meer weergeven FID measurements are usually reported "as methane," meaning as the quantity of methane which would produce the same response. … Meer weergeven Advantages Flame ionization detectors are used very widely in gas chromatography because of a number of advantages. • Cost: Flame ionization detectors are relatively inexpensive to acquire and operate.
