Calibration sample of ion mobility spectrometer as well as preparation method and use method thereof

Abstract

The invention provides a calibration sample of an ion mobility spectrometer as well as a preparation method and a use method thereof. The preparation method comprises the following steps of: heating or dissolving a plastic raw material into a liquid state; then, adding a standard substance to the plastic raw material in the liquid state; fully and evenly stirring the plastic raw material in the liquid state and the standard substance to form a liquid mixture; and finally, solidifying the liquid mixture to form the calibration sample existing in a solid form. By adopting the technical scheme, the invention solves the technical problems of high preparation and use requirements, inconvenient storage and carrying, unsafety, environmental pollution, and the like due to the organic solution mode of the calibration sample used in the prior art, also simplifies the calibration work of the ion mobility spectrometer and saves time and labor.

Description

technical field [0001] The invention relates to the technical field of chemical substance detection, in particular to a calibration sample for an ion mobility spectrometer, and a method for preparing and using the calibration sample. Background technique [0002] Ion mobility spectrometry technology is a technology developed in the 1970s to separate and detect chemical substances in an atmospheric pressure environment. It has extremely high sensitivity and response speed, and can detect and identify chemical substances in a very short time. It can be used to detect and identify chemical warfare agents, explosives, drugs, environmental pollutants, etc. Initially, ion mobility spectrometry was mainly used in the detection of chemical warfare agents in the military field. Since the technology is fast, sensitive, easy to operate and easy to use, it has been widely used in anti-terrorism, virus detection, security inspection and environmental monitoring since the 1980s. field. ...

AI Technical Summary

Problems solved by technology

[0005] (1) Preparation and on-site use of standard substance solutions require certain test conditions and professional skills, which improves the use conditions of the instrument and limits the popularization and use of ion mobility spectrometers

[0006] (2) Organic solvents are needed to prepare standard substance solutions, and organic solvents are flammable, explosive and volatile, and are not safe to store, carry and use

[0007] (3) Organic solvents are toxic and volatile, which will damage the health of personnel and pollute the environment
