Small mass spectrometer
WebA mass spectrometer (spectrometer cell (8)) for masses 2, 3 and 4 (corresponding to test gases H 2, 3 He and 4 He) is attached to the inlet flange of a turbopump (high vacuum pump (7)). A backing pump evacuates the turbopump through the exhaust valve (6). A test specimen (in DIN EN 1330-8 also referred to as “test object”) is evacuated through the … Mass spectrometry has both qualitative and quantitative uses. These include identifying unknown compounds, determining the isotopic composition of elements in a molecule, and determining the structure of a compound by observing its fragmentation. Other uses include quantifying the amount of a compound in a sample or studying the fundamentals of gas phase ion chemistry (the …
