Scope

Main technical content: 7.2.2 Calibration method 7.2.2.1 Blank sample: Take 100μL of blank blood sample, place it in a headspace vial, add 500μL of secondary water, and inject it using an automatic headspace sampler. No ethanol chromatographic peak should appear on either detector FID1 or FID2. 7.2.2.2 Detection limit: Take 100μL of detection limit calibration working solution, place it in a headspace vial, add 500μL of secondary water, and inject it using an automatic headspace sampler. An ethanol chromatographic peak should appear. Take the baseline in the 1 minute before the ethanol peak as noise, and record the signal-to-noise ratio (S/N) of the ethanol chromatographic peak on both detectors, LOD1 and LOD2.
