| titleOfInvention | Flash thermal desorption-pulse sampling method for rapid and high-sensitivity detection of drugs on site |
| abstract | The invention discloses a method for realizing rapid and high-sensitivity detection of drugs on site by combining pulse purging and halogen light flash thermal analysis. The device in the method mainly comprises the following steps: the device comprises a photo-thermal halogen lamp, a high-temperature resistant quartz optical lens, a high-voltage pulse valve, a heatable thermal desorption micro-area and the like. The method has the main principle that the halogen lamp is used for rapidly heating the heatable thermal desorption micro-area to heat the drugs, and the drugs can be heated to more than 250 ℃ at the focus within 2s, so that the saturated vapor pressure of the drugs is greatly improved, and the diffusion in a sample space is effectively reduced by the constructed narrow micro-thermal desorption area; the combination of the pulse valve for instantaneous high-speed purging can more effectively transmit the sample steam from the heatable thermal desorption micro-area to the ionization area, thereby improving the utilization rate of the sample. The halogen lamp has high flash heat analysis heating speed and small sample residue, and compared with the traditional constant-temperature metal contact type heating, the power consumption is greatly reduced; the combination of the two can fully meet the requirement of the field portable analysis instrument. |
