Determination of toluene solvent residues in the samples of benzene with GC/MS-SIM. Standard curve method of peak area is used as a quantitative method. The heating temperature of the sample was 90℃, the equilibrium time was 30min, SIM m/z 92, m/z 93, 91, 89, and 65. The concentration of toluene was linear in 0-100 g/mL (R2=0.99994). The relative standard deviation of the method was 3.34-6.12%, the recovery was between 95.0~102.4%, the detection limit was 0.3 g/mL, which was in accordance with the requirement of quantitative analysis.
