Abstract
A solvent trap for integration with a mass spectrometry system includes an enclosure defining an internal space; a wet gas inlet port configured to receive a gaseous flow from an ion source; a liquids outlet port configured to enable liquids to flow under gravity from the internal space; and a dry gas outlet port configured to exhaust gas from the internal space.

- and
- a dry gas outlet port configured to exhaust gas from the internal space.
2 more elements
A mass spectrometry system comprising:
- a source configured to generate ions from a liquid sample;
- a mass analyzer configured to determine the mass-to-charge ratio of the ions;
- and
- a solvent trap including:
- an enclosure defining an internal space;
- a wet gas inlet port configured to receive a gaseous flow from an ion source;
- a liquids outlet port configured to enable liquids to flow under gravity from the internal space;
- and
- a dry gas outlet port configured to exhaust gas from the internal space.
6 more elements
A method for operating a mass spectrometer, comprising:
- supplying a liquid sample to an ion source;
- nebulizing the liquid sample;
- exhausting excess gases saturated with solvent from the liquid sample to an integrated solvent trap, the integrated solvent trap including an internal volume, a first gaseous inlet, a gaseous outlet, and a liquids outlet;
- separating at least a portion of the solvent from the excess gases within the internal volume;
- draining the portion of the solvent in liquid form from the internal volume by way of the liquids outlet;
- exhausting the excess gases from the internal value by way of the gaseous outlet.
