Abstract

A device for mass spectroscopy comprising a chamber configured to provide an atomization source, a boost device configured to provide radio frequency energy to the chamber, and a mass analyzer in fluid communication with the chamber and configured to separate species based on mass-to-charge ratios is disclosed. In certain examples, a boost device may be used with a flame or plasma to provide additional energy to a flame or plasma to enhance desolvation, atomization, and/or ionization.

First claim

What is claimed is:

1. A method comprising:
providing inductive energy into a chamber from an induction device to sustain an atomization source at a first area within the chamber using inductive energy from the induction device; and
providing additional radio frequency energy from a boost device into a second area of the chamber different from the first area of the chamber, in which the boost device is separate from the induction device and in which the first area of the chamber has the same diameter as the second area of the chamber, and wherein the boost device comprises an aperture that receives the second area of the chamber to position the boost device around the second area of the chamber, and wherein the boost device comprises a wire coil that wraps around the second area of the chamber.

2. The method of claim 1 , further comprising configuring the induction device as an induction coil.

3. The method of claim 1 , further comprising configuring the provided additional radio frequency energy to comprise a frequency of about 25 MHz to about 50 MHz.

4. The method of claim 1 , further comprising configuring the provided additional radio frequency energy to comprise a power of about 100 Watts to about 2,000 Watts.

5. The method of claim 1 , further comprising detecting species in the chamber using a detection device.

6. The method of claim 1 , further comprising providing species in the chamber to a mass analyzer.

7. The method of claim 1 , further comprising configuring the atomization source as an inductively coupled plasma.

8. The method of claim 1 , further comprising configuring the atomization source as a flame.

9. The method of claim 1 , further comprising configuring the provided radio frequency energy as pulsed radio frequency energy.

10. A method comprising:
providing inductive energy into a first area of a first chamber from an induction device to sustain an atomization source within the first chamber using inductive energy from an induction device; and
providing radio frequency from a boost device into an area of a second chamber, in which the second chamber is a different chamber than the first chamber and is fluidically coupled to the first chamber, in which the boost device is separate from the induction device, in which the first chamber is spatially separate from the second chamber, and in which the first chamber has the same diameter as the second chamber, wherein the boost device comprises an aperture that receives the area of the second chamber to position the boost device around the area of the second chamber, and wherein the boost device comprises a wire coil that wraps around the area of the second chamber.

11. The method of claim 10 , further comprising configuring the induction device as an induction coil.

12. The method of claim 10 , further comprising configuring the provided radio frequency energy to comprise a frequency of about 25 MHz to about 50 MHz.

13. The method of claim 10 , further comprising configuring the provided radio frequency energy to comprise a power of about 100 Watts to about 2,000 Watts.

14. The method of claim 10 , further comprising detecting species in the second chamber using a detection device.

15. The method of claim 10 , further comprising providing species in the second chamber to a mass analyzer.

16. The method of claim 10 , further comprising configuring the atomization source as an inductively coupled plasma.

17. The method of claim 10 , further comprising configuring the atomization source as a flame.

18. The method of claim 10 , further comprising providing an interface between the first chamber and the second chamber.
