Direct sample analysis device adapters and methods of using them

摘要

Certain embodiments described herein are directed to adapters for use in coupling a direct sample analysis device to an analytical instrument such as, for example, a mass spectrometer. In some examples, the adapter can include an internal coupler separated from an external coupler through an insulator.

主权项

1. An adapter for installing a direct sample analysis device on a mass spectrometer, the adapter comprising:
a capillary sleeve configured to couple to a capillary inlet of the mass spectrometer, in which the capillary sleeve is configured to couple to the capillary inlet through a friction fit between outer surfaces of the capillary inlet and inner surfaces of the capillary sleeve; and an end cap extension configured to couple to the capillary sleeve, in which the capillary sleeve and end cap extension are configured to provide fluidic coupling between a sample holder of the direct sample analysis device and the mass spectrometer through the capillary inlet.
