Abstract

The invention relates to a chemical ionisation method for ionising a sample (70) including analytes to be ionised. The method includes ionising reagent molecules of a reagent (60) in a reagent ionisation ion source (3) with a reagent ionisation method to reagent ions and providing the reagent ions in a reaction chamber (2). The method further includes introducing the sample (70) including the analytes into the reaction chamber (2), thus allowing the analytes to react in the reaction chamber (2) with the reagent ions to form analyte ions. The reagent (60) is a heterocyclic aromatic compound, such as Pyrimidine, Pyridine, Furan, Thiophene, 1H-Imidazole, Pyrrole, or Indole. With the reagent ionisation method, an amount of energy, which is deposited on each one of the reagent molecules being ionised, is less than 5 eV more than an ionisation potential of the reagent molecules. The invention further relates to a corresponding chemical ionisation arrangement (100).
