Example Embodiment
[0032] Example 1:
[0033] 1. Instruments and reagents:
[0034] Tert-butyl methyl ether and methanol are all chromatographic grade reagents, sodium hydroxide and sodium sulfate are all analytical reagents; distilled water meets the requirements of first grade water in GB / T6682.
[0035] API4000 quadrupole tandem mass spectrometer; water bath constant temperature oscillator; Swiss Mettler AE163 electronic balance (sensitivity: 0.0001g).
[0036] 2. Sample processing:
[0037] Cut the sample first: the cutting method of tipping paper for cigarettes is carried out in accordance with the regulations of YC171-2008, that is, a sample of tipping paper with a length of 200mm and a width of 40mm is accurately cut (should include a single side); the lining paper for cigarettes The cutting method is carried out in accordance with YC264-2008, that is, the cutting area is about 170cm 2 (That is equivalent to the area of inner liner paper used in ordinary cigarette soft box packaging); the cutt...
Example Embodiment
[0043] Example 2:
[0044] According to the measurement method described in Example 1, another cigarette tipping paper sample was selected, and 4-aminoazobenzene was not detected in the sample.
Example Embodiment
[0045] Example 3:
[0046] According to the measurement method described in Example 1, another cigarette liner paper sample was selected, and 4-aminoazobenzene was not detected in the sample.
