Embodiment Construction

[0037] Below, the present invention will be described in detail with reference to the accompanying drawings.

[0038] Such as figure 1 As shown, this embodiment provides a FastGC column improvement device 100 that can be used in conjunction with an ion mobility spectrometer, which is connected to the ion mobility spectrometer IMS. The mixture sample vapor and carrier gas in the sampling system of the ion mobility spectrometer enter the FastGC column improvement device 100, and after being separated by GC, the separated sample molecules enter the migration tube of the ion mobility spectrometer to continue effective analysis and detection .

[0039] Such as Figure 2 to Figure 8 As shown, the FastGC column improvement device 100 includes: a FastGC column 101 , a through-hole connecting seat 102 , a connecting piece 103 for sealingly connecting the FastGC column 101 and the through-hole connecting seat 102 , and a hollow connecting rod 104 .

[0040] Wherein, the through-hole ...

Abstract

The invention provides an improved FastGC column device capable of combination with an ion mobility spectrometer. Through hole connecting bases on two sides of the FastGC column and connecting parts for connecting the FastGC column with the through hole connecting bases in a sealing manner are arranged, and hollow connecting rods which can be in sealing connection with the ion mobility spectrometer are arranged at the other ends of the through hole connecting bases, so that sealing connection of the improved FastGC column device and the ion mobility spectrometer is achieved; furthermore, the improved FastGC column device also comprises a wound FastGC column and a thermal box for the connecting parts and the through hole connecting bases, wherein a heating device and a temperature sensor are arranged in the thermal box, therefore, the temperature controllability of the FastGC column is realized; all parts of the improved FastGC column device are connected simply and conveniently, the installation and the maintenance are convenient; besides, the outsourced thermal box is omitted, the cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of substance detection, in particular to an improved FastGC column that can be used in conjunction with an ion mobility spectrometer. Background technique [0002] Gas chromatography (gas chromatography, GC) method is an established analytical technique, which uses the different distribution coefficients of the components to be separated between the mobile phase (carrier gas) and the stationary phase, and the components to be separated have different distribution coefficients. points for separation. When the mobile phase and the stationary phase are in relative motion, the distribution of these components between the two phases is repeated. Even if there is a slight difference in the distribution coefficient of the components, the separation of each component can be realized in the end. [0003] Ion Mobility Spectrometry (IMS) is a technology for separating ions under atmospheric pressure conditions. Accord...
