Description

一种气体收集装置A gas collection device

技术领域technical field

本实用新型涉及植物组织测定技术领域,尤其涉及一种用于气相色谱法的气体收集装置。The utility model relates to the technical field of plant tissue measurement, in particular to a gas collection device for gas chromatography.

背景技术Background technique

目前,在使用气相色谱法定量分析植物组织释放的气体化合物时,需要预先收集植物阻止释放的混合气样,然后将气样注入气相色谱后才能测定特定化合物含量。At present, when using gas chromatography to quantitatively analyze the gas compounds released by plant tissues, it is necessary to collect the mixed gas samples that the plants prevent from releasing, and then inject the gas samples into the gas chromatograph to determine the content of specific compounds.

现有收集气样的通用方法是将植物组织放入一个固定体积的玻璃密闭器皿中,如图1所示,该玻璃器皿4用胶塞封口,在胶塞打孔并插入两根玻璃管5,玻璃管5之间用胶皮管6连通。取样时,用微量进样器插入胶皮管6中吸取一定体积气样用于气相色谱分析。The general method of collecting gas samples is to put plant tissue into a fixed-volume glass airtight container, as shown in Figure 1, the glass container 4 is sealed with a rubber stopper, and two glass tubes 5 are punched and inserted into the rubber stopper. , The glass tubes 5 are communicated with rubber tubes 6 . When sampling, use a micro-sampler to insert a certain volume of gas sample into the rubber tube 6 for gas chromatographic analysis.

但是,这种传统收集气样的方法有四个缺点:However, this traditional method of collecting gas samples has four disadvantages:

第一,进行定量分析时,需要排水法测定器皿内空余体积,操作繁琐,容易造成误差;First, when performing quantitative analysis, it is necessary to measure the empty volume in the vessel by the drainage method, which is cumbersome to operate and easily causes errors;

第二,该器皿本身笨重,不易搬运,携带不便;Second, the container itself is heavy, difficult to carry, and inconvenient to carry;

第三,在收集气样进行测定时,植物组织不能受到破坏作用,而器皿内的空余体积是由组织间隙决定的,故当所测定组织间间隙较大而释放的化合物含量又较少时,很难收集到足够的化合物进行分析测定;Third, when collecting gas samples for measurement, the plant tissue cannot be damaged, and the empty volume in the vessel is determined by the tissue gap, so when the measured tissue gap is large and the released compound content is small, it is very difficult It is difficult to collect enough compounds for analysis and determination;

第四,对某些组织需要使用多个组织样品用于收集气样,造成了样品浪费。Fourth, for some tissues, it is necessary to use multiple tissue samples for collecting gas samples, resulting in waste of samples.

因此,针对以上不足,需要一种能够方便快捷地收集任何植物组织释放的气样,可随意定量封闭装置内的空余体积,且通过使用单个样品即可完成收集测定的气体收集装置。Therefore, in view of the above deficiencies, there is a need for a gas collection device that can conveniently and quickly collect gas samples released by any plant tissue, can freely quantify the empty volume in the closed device, and can complete the collection and measurement by using a single sample.
