Abstract
This invention describes an ion mobility spectrometer system for chemical detection in the field. The system allows: a high throughput operation, an interface to new ionization methods, and an interface to a mass spectrometer.
Claims21
A multi-function sample introduction apparatus comprising:
- a sample loading port allows introducing a sample into an analytical instrument using a thermal desorber and/or an electrospray apparatus which both function in the same sample introduction apparatus;
- and an opening and/or interface to an ionization chamber of the analytical instrument.
A removable sample holder for sample analysis comprising:
- a thermal desorption and/or electrospray ionization function in the same sample holder;
- a means to receive the sample in liquid and/or solid form;
- a substantially sealed inner chamber;
- and at least one opening facing an analytical instrument having a function of releasing sample as vapor or charge liquid via an electrospray mechanism.
1 more element
A sample introduction method comprising:
- loading a sample into a removable sample holder;
- inserting the removable sample holder into a sample loading port;
- and vaporizing some sample under a controlled temperature and/or temperature gradient into the ionization chamber using a thermal desorber or electrospraying the sample into an analytical instrument using the same sample holder.
A multi-function sample introduction method comprising:
- introducing a sample into an analytical instrument using a sample port that allows thermal desorption and/or electrospray which both function in the same sample introduction apparatus;
- and transporting the sample to an ionization chamber of the analytical instrument through an opening and/or interface.
