IMPROVED METHODS FOR HIGH FIELD ASYMMETRIC WAVEFORM SPECTROMETRY (HIFAWS)

摘要

The present invention provides improved methods for identifying target molecules using High Field Asymmetric Waveform Spectrometry (HiFAWS). The methods in particular substantially eradicate the effect of water on the field dependency of target molecule ions, by the use of carrier gases comprising a low molecular weight solvent having a proton affinity greater than that of water.
