Abstract: The present invention relates to an ion trap mass spectrometry. The ion trap mass spectrometry measures the mass of ions by a method of radio frequency (RF) signal measurement voltage to mass spectrometry while compensating changes in a scan waveform which is used for generating an RF signal used for the measurement of the mass of the ions. According to the present invention, the ion trap mass spectrometry can accurately measure the mass of the ions on the basis of the RF signal measurement voltage even though the linearity of the RF signal used for measuring the mass of the ions changes.

Abstract: The present invention relates to a volatile material concentrating-transferring device including a metering transfer valve. The present invention provides a volatile material concentrating-transferring device including a metering transfer valve, which adsorbs a volatile material to a nanocomposite material by passing air through the air guiding channel of a concentrator; prevents air from flowing out of the concentrator by blocking an intake valve and an exhaust valve installed on both ends of the air guiding channel; desorbs the volatile material adsorbed to the nanocomposite material by operating a heater installed in the air guiding channel while mixing, with a small amount of air remaining in the air guiding channel, the desorbed volatile material; and transfers a predetermined amount of the volatile material mixed with air through a metering transfer valve and a transfer hole installed on the exhaust valve to a mass spectrometer. The volatile material concentrating-transferring device including a metering transfer valve according to the present invention has concentrating efficiency increased owing to the volatile material mixed with a small amount of air remaining in the air guiding channel of the concentrator; has mixing time reduced and mixture uniformized owing to the volatile material mixed with air in a small space; has the volume of the device reduced owing to the structure of a small space; enables the certification of the accurate amount of the volatile material owing to the predetermined amount of the volatile material transferred through the metering transfer valve to the mass spectrometer; thus enables the accurate mass spectrometry and quantitative analysis of the volatile material; and enables the separate management of the nanocomposite material having the volatile material adsorbed thereto owing to the separable concentrator.
