Devices and systems including a boost device
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.
1. A device for mass spectroscopy comprising:
a chamber configured to provide an atomization source;
an energy delivery mechanism configured to provide radio frequency energy into a first area of the chamber to sustain the atomization source in the chamber;
a boost device configured to provide additional radio frequency energy into a second area of the chamber different from the first area of the chamber; and
a mass analyzer in fluid communication with the chamber and configured to separate species based on mass-to-charge ratios.
2. The device of claim 1 , in which the mass analyzer is selected from the group consisting of a scanning mass analyzer, a magnetic sector analyzer, a quadrupole mass analyzer, and an ion trap analyzer.
3. The device of claim 1 , further comprising a detection device in fluid communication with the mass analyzer.
4. The device of claim 3 , in which the detection device is selected from the group consisting of an electron multiplier and a Faraday cup.
5. The device of claim 3 , further comprising a processing device in electrical communication with the detection device.
6. The device of claim 5 , in which the processing device is configured to access a database.
7. The device of claim 1 , in which the chamber is configured to provide an atomization source that is selected from the group consisting of a flame, an inductively coupled argon plasma, a spark and an arc.
8. The device of claim 1 , in which the boost device is configured to provide radio frequency energy in a pulsed mode or a continuous mode.
9. The device of claim 1 , in which the boost device is configured to provide radio frequency energy having a frequency of about 25 MHz to about 50 MHz.
10. The device of claim 1 , in which the boost device is configured to provide radiofrequency energy at a power of about 100 Watts to about 2,000 Watts.
11. The device of claim 1 , further comprising a second chamber in fluid communication with the chamber comprising the atomization source.
12. The device of claim 11 , in which the second chamber further comprises a boost device configured to provide radio frequency energy to at least a portion of the second chamber.
13. The device of claim 12 , in which the boost device of the second chamber is configured to provide radio frequency energy of about 25 MHz to about 50 MHz and to provide radiofrequencies at a power of about 100 Watts to about 2,000 Watts.
14. The device of claim 12 , in which the second chamber is in fluid communication with a vacuum pump configured to draw sample front the first chamber into the second chamber.
15. The device of claim 12 , in which the second chamber further comprises an interface comprising an orifice for introducing sample into the second chamber.
16. The device of claim 15 , in which the interface is configured to introduce sample front the first chamber into the second chamber so that the sample is diluted by less than about 15:1 with carrier gas.
