| 摘要 |
An ion spectrometer apparatus is disclosed having an ion source, an ion mobility spectrometer device such as a FAIMS cell, and a capillary for transporting ions from the ion source to the entrance of the FAIMS cell. The capillary is heated to promote evaporation of solvent from incompletely desolvated droplets entering the capillary inlet, thereby preventing or minimizing operational problems associated with the presence of wet material in the FAIMS cell. The FAIMS cell may be used to selectively transmit ions to a mass analyzer.
