When the mean free path of gas molecules in a vacuum system is on the order of a few cm or more (at < 10-3 Torr), electrons of a suitable energy will create mostly positive ions at a rate depending on the gas pressure, temperature and species of the individual molecules. A hot filament is the source of the electrons, the energy being 70 ev and the . Principles of Infrared Analysis:Infrared (IR) absorption (or reflection for solids) is a technique that can be used successfully for continuous chemical analysis of a process. The IR region of the electromagnetic spectrum is generally considered to cover wavelengths from 0.8 to 1000µ m. These limits, expressed in frequency terms (cm-1, wave numbers or the number .
Introduction Blood gas analyzers are sophisticated medical devices designed to measure the levels of various gases and electrolytes in a patient's blood sample.
