Method and apparatus for temperature control during sample analysis

摘要

A method of detecting an explosive material, and an analyzer and computer program products that may perform such methods. A method may include illuminating at least a portion of the material with light, and monitoring the temperature of the illuminated portion. T power or location of the illuminating light may be altered in response to the monitored temperature. Raman spectral data are produced in response to Raman radiation emitted from the portion in response to the light. The composition of the material may be analyzed based on the Raman spectral data or generating an indication to an operator that the material cannot be safely analyzed.

1. A method of detecting an explosive material, comprising:
illuminating at least a portion of the material with light; monitoring the temperature of the illuminated portion, said monitoring including analyzing a change or a rate of change in thermal infra-red radiation resulting from a temperature change at the portion caused by the illumination, said analyzing including monitoring a rate of change in a peak width in Raman spectral data; altering the power or location of the illuminating light in response to the monitored temperature; producing Raman spectral data in response to Raman radiation emitted from the portion in response to the light; analyzing the composition of the material based on the Raman spectral data or generating an indication to an operator that the material cannot be safely analyzed.
