IMPROVED IONISATION OF GASEOUS SAMPLES

摘要

A method of mass spectrometry or ion mobility spectrometry is disclosed comprising: providing an analyte201;supplying a matrix204 compound to said analyte 201 such that saidanalyte 201 dissolves in saidmatrix204; formingfirst dropletsof the dissolved analyte 205;and colliding saidfirst droplets 205 with a collision surface 209. The use of matrix improves the analyte ion signal.
