Time-of-flight mass spectrometry (TOFMS) is a method of mass spectrometry in which an ion's mass-to-charge ratio is determined by a time of flight measurement. Ions are accelerated by an electric field of known strength. This acceleration results in an ion having the same kinetic energy as any other ion that has the same charge. The velocity of the ion depends on the mass-to-charge ratio (hea… WebEurofins has invested in automated combustion ion chromatography instrumentation to allow this analysis to be conducted for AFFF concentrates, water and solid samples such …
