Gas-Phase Atmospheric Pressure Chemical Ionization Source (vAPCI)

Gas-Phase Atmospheric Pressure Chemical Ionization Source (vAPCI) With Advion expression CMS Mass spectrometry coupling It can be used for headspace analysis of gas samples. It is simple and rapid to operate, requiring no sample pretreatment whatsoever. Although the mass spectrometer boasts excellent performance, it still faces certain challenges when analyzing gaseous samples; therefore, combining its use with... vAPCI The ion source can be easily resolved. The sample inlet is connected to a heated transfer line, which then leads via the transfer line to... APCI Connected to the ion source, ionization is then achieved via a corona discharge needle.

vAPCI With expression CMS Combined use

Gas-Phase Atmospheric Pressure Chemical Ionization Source (vAPCI) With Advion Small desktop mass spectrometer expression CMS Combination—no sample pretreatment required, enabling convenient and rapid analysis of volatile substances such as sample headspace, breath gas, or air.
