Claim 2:
3. The microplastic detection device based on a pyrolysis-mass spectrometry technology according to claim 2, wherein the temperature sensing device is a temperature measurement wire; and the temperature programming device comprises a temperature measurement wire, a temperature conversion circuit, an acquisition card, a control system, a power supply and a heating module circuit which are electrically connected in sequence, wherein after the power supply is turned on, a temperature collected by the temperature measurement wire is converted into an electrical signal by means of the temperature conversion circuit, and then the electrical signal is received by the acquisition card; and an output power of the heating module circuit is adjusted by means of a PID algorithm of the control system, that is, a heating power of an electric heating wire connected with the heating module circuit is adjusted, and thus a heating rate within the quartz tube is adjusted.
