| titleOfInvention | FAIMS apparatus and method for detecting trace amounts of a vapour in a carrier gas |
| abstract | Disclosed is a method and apparatus for detecting trace levels of a vapour in a carrier gas stream. A method according to the instant invention comprises the steps of providing a flow of a carrier gas through an analyzer region of a high field asymmetric waveform ion mobility spectrometer ( 22 ), the carrier gas including a first gas and a trace amount of a vapour. At least a first type of indicator ions are introduced into the analyzer region, and a compensation voltage for transmitting the at least a first type of indicator ions through the analyzer region, in the presence of the flow of a carrier gas and at a given asymmetric waveform voltage, is determined. The determined compensation voltage is compared to calibration data relating to a compensation voltage for transmitting the at least a first type of indicator ions through the analyzer region at the given asymmetric waveform voltage in the presence of each of a plurality of different known trace amounts of the vapour mixed with the first gas. In this way, an amount of the vapour in the carrier gas is determined, absent a step of ionizing a substantial portion of the vapour. |
