ION SOURCE FOR LOWER LIMITS OF DETECTION IN SPECTROMETRIC MEASUREMENTS

摘要

Ion source for lower limits of detection in mass spectrometry and ion mobility spectrometry that uses restriction of flow of gases and vapors at the outlet of ion source into the ambient atmosphere (10) and supplying an auxiliary medium into the working region of ion source (3) in order to achieve an increase of pressure in the working region of ion source (3) which leads to increase of signal intensity by order (s) of magnitude.
