Description
本創作有關於一種溶解於水中的揮發性有機物定量裝置，特別是有關於一種吹氣捕捉分析系統應用於水溶解的氣體定量裝置。The present invention relates to a volatile organic matter metering device dissolved in water, and more particularly to a gas metering device for a water-dissolving analysis system for water dissolution.
吹氣捕捉分析方法常應用於檢測水溶液中的有機揮發物質，其主要原理為對水溶液通入惰性氣體，以使揮發物質脫離水溶液之後吸附於吸附劑上而濃縮，然後經高溫脫附，再進一步將被濃縮揮發性有機物質導入氣相層析質譜儀（GC/MS）中進行分析，此種方法可進一步應用於水源及海域水中揮發性物質的監測上。The blow trapping analysis method is often applied to the detection of organic volatile substances in an aqueous solution. The main principle is to introduce an inert gas into the aqueous solution, so that the volatile matter is detached from the aqueous solution and then adsorbed on the adsorbent to be concentrated, and then desorbed at a high temperature, and further The concentrated volatile organic substances are introduced into a gas chromatography mass spectrometer (GC/MS) for analysis, and the method can be further applied to the monitoring of volatile substances in water and sea water.
檢測時，若設計可使樣品溶液進行定量的檢測設置，可作為獲得較具一定比較基礎的數值，例如，於中華民國專利第M500890號中揭示一種可自動進樣及定量的全自動分析裝置，該裝置解決了需以人工的方式進樣的問題，並直接於管線中作進樣定量，亦可達到連續供樣的功效，因而可進行連續性的檢測。然而，目前僅有在供應惰性氣體的管線上設置壓力調節裝置，對通入樣品中的惰性氣體進行定量設定等，當欲對水溶液中溶解之揮發性有機物進行吹氣捕捉分析時，無法直接利用分析一定體積量之標準氣體以精確定量分析水溶液中揮發性有機物的濃度，因而難以即時取得現場水樣中各種溶解之揮發性物種的濃度。。In the detection, if the design can make the sample solution to be quantitatively set, it can be used as a basis for obtaining a certain comparison. For example, a fully automatic analysis device capable of automatic injection and quantification is disclosed in the Republic of China Patent No. M500890. The device solves the problem of requiring manual injection, and directly performs injection sampling in the pipeline, and can also achieve the effect of continuous sample supply, thereby enabling continuity detection. However, at present, only a pressure regulating device is provided on a pipeline for supplying an inert gas, and the inert gas introduced into the sample is quantitatively set, and the like, when it is desired to perform a blow trapping analysis on the volatile organic matter dissolved in the aqueous solution, it cannot be directly utilized.
