Secondary ionization of chemical warfare agent simulants: atmospheric pressure ion mobility time-of-flight mass spectrometry.
For the first time, the use of a traditional ionization source for ion mobility spectrometry (radioactive nickel ((63)Ni) beta emission ionization) and three alternative ionization sources (electrospray ionization (ESI), secondary electrospray ionization (SESI), and electrical discharge (corona) ionization (CI)) were employed with an atmospheric pressure ion mobility orthogonal reflector time-o...
متن کاملRapid screening of aqueous chemical warfare agent degradation products: ambient pressure ion mobility mass spectrometry.
The use of electrospray ionization ambient pressure ion mobility spectrometry with an orthogonal reflector time-of-flight mass spectrometer to analyze chemical warfare (CW) degradation products from aqueous environmental samples has been demonstrated. Certified reference materials of analytical standards for the detection of Schedule 1, 2, or 3 toxic chemicals or their precursors as defined by ...
متن کاملDetection of a chemical warfare agent simulant in various aerosol matrixes by ion mobility time-of-flight mass spectrometry.
For the first time, a traditional radioactive nickel (63Ni) beta emission ionization source for ion mobility spectrometry was employed with an atmospheric pressure ion mobility orthogonal reflector time-of-flight mass spectrometer (IM(tof)MS) to detect a chemical warfare agent (CWA) simulant from aerosol samples. Aerosol-phase sampling employed a quartz cyclonic chamber for sample introduction....
متن کاملIon mobility spectrometer with radial collisional focusing.
An ion mobility spectrometer that has its mobility cell as a 20-segment quadrupole and functionally the q2 of a triple-quadrupole mass spectrometer has been assembled and tested. The combination of high cell pressure (maximum of 4 Torr of helium) and low axial field (20-160 V per 20.2 cm) results in negligible internal excitation of the ions despite applications of rf and axial fields. The pres...
متن کاملSurface detection of chemical warfare agent simulants and degradation products
Chemical warfare agent (CWA) simulants as well as their degradation and hydrolysis products were detected from surfaces using thermal desorption ion mobility spectrometry (TD-IMS). CWA simulant materials that closely mimic the chemical structures of real CWA G/V-type nerve and S-type vesicant simulants were used in this study. Reduced mobility constants (K0) in air were reported for 20 compound...
