Embodiment 1
[0024] The method for simultaneously measuring 14 kinds of sour components in cigarette mainstream smoke of the present embodiment comprises the following steps:
[0025] 1) Smoke the balanced and screened brand 1 cigarettes according to the standard smoking conditions specified in YC / T29-1996, use two Cambridge filters to capture the particulate matter in the mainstream smoke of 8 cigarettes, and place them in 50 Add 10 mL of acetone solution to a stoppered Erlenmeyer flask, shake on a shaker at room temperature for 20 minutes, add 10 μL of trans-3-hexenoic acid internal standard solution, mix well, take 1 mL of supernatant, add derivatized Chemical reagent BSTFA 50 μL, placed in a 30°C water bath and heated for 50 min to obtain a cigarette smoke sample;
[0026] 2) GC-MS is used to detect the flue gas sample obtained in step 1);
[0027] The chromatographic conditions are: chromatographic column: DB-5MS (60 m×0.25 mm×0.25 μm); carrier gas: He; column flow rate: 1mL / min; inl...
Embodiment 2
[0031] The method for simultaneously measuring 14 kinds of sour components in cigarette mainstream smoke of the present embodiment comprises the following steps:
[0032] 1) Suck the balanced and screened brand 2 cigarettes according to the standard smoking conditions specified in YC / T29-1996, use two Cambridge filters to capture the particulate matter in the mainstream smoke of 8 cigarettes, and place them at 50 Add 40 mL of acetone solution to a stoppered Erlenmeyer flask, shake on a shaker at room temperature for 30 minutes, add 40 μL of trans-3-hexenoic acid internal standard solution, mix well, take 1 mL of supernatant, add derivative Chemical reagent BSTFA 60 μL, placed in a 30°C water bath and heated for 70 min to obtain cigarette smoke samples;
[0033] 2) GC-MS is used to detect the flue gas sample obtained in step 1);
[0034] Chromatographic conditions and mass spectrometry conditions are the same as in Example 1.

Embodiment 3
[0037] The method for simultaneously measuring 14 kinds of sour components in cigarette mainstream smoke of the present embodiment comprises the following steps:
[0038] 1) Suck the balanced and screened brand 3 cigarettes according to the standard smoking conditions specified in YC / T29-1996, use two Cambridge filter discs to capture the particulate matter in the mainstream smoke of 8 cigarettes, and place them at 50 Add 50 mL of acetone solution to a stoppered Erlenmeyer flask, shake on a shaker at room temperature for 40 minutes, add 50 μL of trans-3-hexenoic acid internal standard solution, mix well, take 1 mL of supernatant, add derivatized Chemical reagent BSTFA 90 μL, placed in a 30 °C water bath and heated for 90 min to obtain a cigarette smoke sample;
[0039] 2) GC-MS is used to detect the flue gas sample obtained in step 1);
[0040] Chromatographic conditions and mass spectrometry conditions are the same as in Example 1.
[0041] Table 3 shows the detection resul...
