Abstract
A method is disclosed for detecting organophosphorus compounds and illicit drugs using an ion detector. A vapor sample containing at least one analyte and at least one dopant is ionized. A proton-bound adduct ion is formed between the analyte and the dopant in a reaction region defined between the ionization source and the ion detector.
Claims26
A method, comprising:
- forming a proton-bound adduct ion between at least one organophosphorus compound (OPC) and at least one secondary or tertiary amine in a reaction region defined between an ionization source and an ion detector;
- and
- detecting the proton-bound adduct ion with the ion detector.
A method, comprising:
- ionizing a vapor sample with an ionization source, the vapor sample containing at least one organophosphorus compound (OPC) and at least one secondary or tertiary amine;
- introducing the ionized vapor sample containing the at least one OPC and at least one secondary or tertiary amine therein into a reaction region defined between the ionization source and an ion detector;
- forming at least one proton-bound adduct ion between the at least one OPC and the at least one secondary or tertiary amine therein;
- and
- detecting the at least one proton-bound adduct ion with the ion detector.
