Fluid ionization vaporization inlet for introduction of samples to spectroscopy instruments and methods of performing the same

摘要

A fluid ionization and vaporization inlet provides for the ionization and vaporization of samples to be delivered to analytical instrumentation of the scientist's choice. A sample may be injected through a septum onto a sample plate whereby heat, direct current, or both can be applied to ionize and/or vaporize the sample into a carrier gas, which is then provided to the analytical instrumentation. A continuous fluid sample may also be provided to the fluid ionization and vaporization inlet wherein it is heated to vaporize the sample, and then excited volatile molecules pass through a gas permeable membrane and combined with a carrier gas, which in turn is provided to the analytical instrumentation.

1. A fluid ionization vaporization inlet comprising
a base, where the base comprises a chamber; a sample plate, where the sample plate is housed within the chamber; a septum alignment plate, where the septum alignment plate mates with the base; an injection septum, where the injection septum mates with the septum alignment plate; a gas inlet, where the gas inlet is in fluid communication with the chamber; a gas outlet, where the gas outlet is in fluid communication with the chamber; and a sample outlet, where the sample outlet is in fluid communication with the chamber.
