Claim 9:
10. The microplastic detection method based on a pyrolysis-mass spectrometry technology according to claim 8, wherein in the step 3), the temperature-programmed process comprises the following steps: setting a heating target temperature within the quartz tube, starting a heating control program, reading a current temperature by the program, calculating a temperature difference by means of a PID algorithm, adjusting an output power of the heating module to achieve full power output and rapid temperature increase; and wherein when a current temperature is close to the set target temperature and a temperature difference is decreased, reducing the power output; when the current temperature is greater than the set target temperature, stopping heating; and when the current temperature is lower than the set target temperature, starting heating, and adjusting the output power according to the temperature difference.
