Embodiment 1
[0021] The method for simultaneously measuring 14 kinds of burnt-sweet aroma components in cigarette mainstream smoke of the present embodiment comprises the following steps:
[0022] 1) Suck the balanced and screened brand 1 cigarettes according to the standard smoking conditions specified in YC / T29-1496, use two Cambridge filter discs to capture the particulate matter in the mainstream smoke of 8 cigarettes, and then filter the Cambridge filter Place the tablet in a 50 mL Erlenmeyer flask with a stopper and spread it flat on the bottom of the bottle, add 10 μL of internal standard solution, add 10 mL of isopropanol solution, shake at room temperature for 20 min, take 2 mL of supernatant, and obtain a smoke sample ;
[0023] 2) GC-MS is used to detect the flue gas sample obtained in step 1);
[0024] The chromatographic conditions are: chromatographic column: DB-5MS (60 m×0.25 mm×0.25 μm); carrier gas: He; column flow rate: 1mL / min; inlet temperature: 250°C; temperature prog...
Embodiment 2
[0028] The method for simultaneously measuring 14 kinds of burnt-sweet aroma components in cigarette mainstream smoke of the present embodiment comprises the following steps:
[0029] 1) Suck the balanced and screened brand 2 cigarettes according to the standard smoking conditions specified in YC / T29-1496, use two Cambridge filter discs to capture the particulate matter in the mainstream smoke of 8 cigarettes, and then filter the Cambridge filter Place the tablet in a 50 mL Erlenmeyer flask with a stopper and lay it flat on the bottom of the bottle, add 20 μL of internal standard solution, add 20 mL of isopropanol solution, shake at room temperature for 25 min, take 2 mL of supernatant, and obtain a smoke sample ;
[0030] 2) GC-MS is used to detect the flue gas sample obtained in step 1);
[0031] Chromatographic conditions and mass spectrometry conditions are the same as in Example 1.

Embodiment 3
[0034] The method for simultaneously measuring 14 kinds of burnt-sweet aroma components in cigarette mainstream smoke of the present embodiment comprises the following steps:
[0035] 1) Suck the balanced and screened brand 3 cigarettes according to the standard smoking conditions specified in YC / T29-1496, use two Cambridge filter discs to capture the particulate matter in the mainstream smoke of 8 cigarettes, and then filter the Cambridge filter Place the tablet in a 50 mL Erlenmeyer flask with a stopper and spread it flat on the bottom of the bottle, add 30 μL of internal standard solution, add 30 mL of isopropanol solution, shake at room temperature for 30 min, take 2 mL of supernatant, and obtain a smoke sample ;
[0036] 2) GC-MS is used to detect the flue gas sample obtained in step 1);
[0037] Chromatographic conditions and mass spectrometry conditions are the same as in Example 1.
