For 8890/8860 gcs, you can find the lit offset setting in settings>configuration>detectors in the browser interface. A flame ionization detector (fid) is a scientific instrument that measures analytes in a gas stream. The measurement of ion per unit time make this a mass sensitive instrument. The detector's small cell volume and rapid acquisition response make it ideal for both standard and fast c. An acid, such as dilute hydrochloric acid, is added to the test compound. Sorry brother did not understand very well wat you meaning. Flame ionization detectors work on the principle of ions liberated in the combustion of the sample species. Fids are insensitive to h2o, co2, cs2, so2, co, nox, and noble gases because they are not able to be oxidized/ionized by the flame. An fid is among the most commonly used detectors; Detection is achieved by a flame ionization detector (fid).
