WebbInterfaces for LC-MS. MS require ions to be in the gaseous phase and these ions are detected under high vacuum in the MS. In the case of GCMS, target compounds are already separated and eluted in the gaseous state. In this case, they can be directly introduced to the MS unit. The gaseous compounds are ionized through various methods such as ...
