Embodiment 1
[0031] Example 1: Take cocaine as an example
[0032] The invention provides a kind of far-infrared detection method of cocaine, and concrete steps are as follows:
[0033] Step 1: Prepare a standard sample of cocaine:
[0034] Take 1 mL of cocaine standard substance with a concentration of 1 mg / mL, drop it on a filter membrane with a diameter of 13 mm, and dry it at 40 ° C to obtain a standard sample of cocaine;
[0035] Step 2: Experimental measurement and establishment of a standard spectral library:
[0036]The standard sample of cocaine that step 1 obtains is put into the sample tank of the instrument, and the instrument is vacuumized, then utilizes the FTIR far-infrared band to measure, and the test environment temperature is 21° C., and detects under vacuum conditions; the far-infrared absorption spectrum of the drug standard The frequency range is 30-350cm -1 ; The number of scans of the instrument is 128 times, and the resolution is 2cm -1 ; Each sample was tested...
