Abstract

The invention discloses a liner tube aging device, which comprises a control box, an airflow distribution device and a heating device; a flow meter, a temperature controller and a time controller areinstalled on the side wall of the control box, the temperature controller is located on one side of the flow meter, and the time controller is located on the lower side of the temperature controller;the airflow distribution device comprises an upper aluminum air chamber and a lower aluminum air chamber, the lower aluminum air chamber is fixedly connected to the top of the control box, and the upper aluminum air chamber is fixedly connected to the upper end face of the lower aluminum air chamber; the heating device comprises an aluminum heating block, and the aluminum heating block is fixedlyconnected to the upper end face of the upper aluminum air chamber; the temperature of a heating rod in a heating module can be set, so that the temperature of a filling material in a liner tube is accurate and controllable, the temperature rising speed is high, the aging of the filling material in the liner tube can be ensured, gradual temperature rising is realized, and the success rate of linertube aging is greatly improved.

Description

technical field [0001] The invention relates to the technical field of biological sample preparation, in particular to a liner aging device. Background technique [0002] The detection of volatile substances by gas chromatography-mass spectrometry (GC-MS) is a relatively perfect technology developed in the past two decades. This technology separates the test sample into single components by gas chromatography. The gas flows out of the chromatographic column at the same time, and the compound separated by the chromatographic column enters the mass spectrometry ion source through the interface, and is converted into ions after being ionized by the ion source, and the chromatographic and mass spectrometric signals are detected at the same time to obtain a complete chromatographic and mass spectrogram. [0003] Among them, the volatile substances are mainly detected and analyzed by liquid sampling, headspace sampling, and sampling after enrichment and desorption by solid-phase m...
