Vv. Pervukhin et al., MASS-SPECTROMETER BASED ON THE MX-7304A ANALYZER WITH DIRECT ION INJECTION FROM THE ATMOSPHERE, Instruments and experimental techniques, 40(5), 1997, pp. 700-701
A mass-spectrometric device is described, which is based on a commerci
al mass analyzer MX-7304A and is intended fur the study of ions formed
at atmospheric pressure. The device has a transparency of no less tha
n 10(-6), a detection threshold of 10(10) ions/cm(3), and a sensitivit
y for aniline under beta-ionization, 10(-8) g/m(3).
