(1) setting drying temperature and time, and performing product drying after centrifugation; wherein the drying temperature is set within the range of 40-80 ℃, and the drying time is set within the range of 6-24 hours; if the set temperature is higher than the set temperature, the temperature is indicated to be too high; if the temperature is lower than the preset temperature, the prompt temperature is too low; if the setting time is more than the time, the prompting time is too long; if the setting time is less than the time, the prompting time is too short;
(2) setting the calcining temperature and time, and carrying out the calcining reaction; wherein the setting range of the calcining temperature is 300-800 ℃, and the setting range of the calcining time is 0.5-12 h; if the set temperature is higher than the set temperature, the temperature is indicated to be too high; if the temperature is lower than the preset temperature, the prompt temperature is too low; if the setting time is more than the time, the prompting time is too long; if the setting time is less than the time, the prompting time is too short;
(3) setting the current required by aging, and starting aging; wherein the current setting range is 80-120 mA; if the set current is lower than the value, the current is low and cannot be aged, and the current is input again; if the set current is higher than the value, the current is indicated to be too high and cannot be aged, and the current is required to be input again;
(4) setting the volume of the extracted ethanol to finish the extraction of the trace agent into the gas to be detected; wherein the volume range of the ethanol is 0.05-0.15 mu L; if the extraction volume is set to be lower than the numerical value, the numerical value is too small; if the extraction volume is set to be higher than this value, an excessive value is indicated.
