Rapid and cheap test is developed on the basis of colorimetric tubes "Hygitest", produced in Bulgaria, which could substitute, in a number of cases, the more expensive chromatographic procedure. The method of gas extraction of the examined material is used in the test, and as measuring instrument are used colorimetric tubes "Hygitest" type "Vinylchloride-1-A", which are supplied with reinforced filter for humidity and with special scale. A specially constructed flask is used for thermal desorption. The test has reproducibility and sensitivity significant for performing screening and routine control on the raw materials for production of packings from polyvinylchloride for nutrition purposes. The method "Vinyl-test" is standardized for control on the free monomer content in the packings for nutrition purposes with branch normal of the Ministry of Health and the State firm "Polychim" OH 02 77051-84 (Change No 1 of 8.07.1991).
基于保加利亚生产的“Hygitest”比色管开发了一种快速且廉价的检测方法，在许多情况下，该方法可以替代更昂贵的色谱法。该检测使用被测物质的气体萃取方法，使用的测量仪器是“Hygitest”型“氯乙烯-1-A”比色管，这些比色管配有强化湿度过滤器和特殊刻度。使用一个特殊构造的烧瓶进行热解吸。该检测方法具有可重复性和灵敏度，对于对用于营养目的的聚氯乙烯包装生产原料进行筛选和常规控制具有重要意义。“乙烯基检测”方法已标准化，用于根据卫生部和国家公司“Polychim”的OH 02 77051-84（1991年7月8日第1号变更）的部门标准，对营养目的包装中的游离单体含量进行控制。
