Claim Text:
1. A method for identifying and/or characterizing ions prepared from sample compounds using vibrational spectroscopy comprising: (1) providing a composition comprising ions of interest from a chemical sample; (2) introducing said ions into a vacuum tube and passing said ions along the tube to a distal end of said tube at reduced pressure; (3) exposing said ions to a field at distal end of said vacuum tube to separate said ions from non-ionic material; (4) directing said ions into an ion trap which is temperature controlled at a temperature no higher than about 50 Kelvin: (5) exposing said ions in said ion trap to a pulsed complexing gas or gas mixture selected from the group consisting of hydrogen in a H (6) extracting said gas-ion adducts from naked ions; and (7) conducting mass spectrometric and/or vibrational analysis on said gas-ion adducts which have been extracted pursuant to step 6.
