| Abstract: | The thermal desorption is an important method for the introduction of liquid and solid samples into an ion mobility spectrometer(IMS).There are the problems of recondensation or decomposition for detecting low-volatile or thermally unstable organic compounds.A rapid thermal desorption device coupled with IMS membrane was developed.A micro-heater and a thermocouple were used to control the temperature of desorption for improving the efficiency of sample introduction.The experiments were carried out for the d... |
