Abstract
A method for collecting and concentrating trace chemicals for subsequent analysis by virtually any type of chemical detector includes providing directed radiation to a sample, or a portion of a sample. An apparatus can include a sampling body for providing radiation.
Claims32
A method comprising:
- providing a sample;
- irradiating the sample using electromagnetic radiation with a wavelength in a range from 150 nm to 270 nm and at an irradiance of 0.1-1000 mW/cm2, wherein the radiation increases an evaporation rate of an analyte within the sample, thereby causing vaporization of the analyte from the sample;
- capturing the vaporized analyte in a vaporization space;
- and
- detecting the vaporized analyte with a detector.
