Method for determining benzene and benzene series in bamboo chopsticks based on automatic headspace-gas chromatography-mass spectrometry

The invention relates to the technical field of chemical analysis and detection, and provides a method for determining benzene and benzene series in bamboo chopsticks based on automatic headspace-gas chromatography-mass spectrometry in order to realize detection of benzene series in bamboo chopsticks, the method comprises the following steps: (1) processing a sample to be detected: cutting the sample to be detected, placing the cut sample in a headspace bottle, carrying out headspace sample injection, and detecting the benzene series in the bamboo chopsticks; detecting by using a GC/MS (Gas Chromatography/Mass Spectrometer); (2) preparing a blank sample: cutting and thoroughly drying a sample to be detected, and putting the sample into a container for later use; and (3) drawing a standard curve: weighing and dissolving a benzene series standard substance, preparing standard solutions with various concentrations according to gradient dilution, putting the blank sample in the step (2) into the standard solution
