  • Unbiased ion identification by multiple ions
    Patent number: 11710625
    Abstract: Disclosed are embodiments directed to a multi-ion identification device, a system and method using the same to utilize chemical ionization in multiple adduct formation from the substances in the sampled gas of a gas sample being addressed to be analyzed in a mass analyzer. The multi-ion identification device includes a buffering region to have the sample flow turbulence decayed before the sample flow entrance to the ionization region)) utilizing chemical ionization by reagents from an ensemble of reagent ion towers.
