Device for producing a single or multiple component test gas from organic-chemical substances |
摘要 |
The invention relates to a device for producing dynamic single or multiple component test gases by evaporating volatile organic compound substances in an evaporating and mixing chamber (3, 4) through which a complementary gas passes. The invention provides a means of generating dynamic test gases consisting of organic-chemical substances with a boiling point range of approximately 25 - 300 DEG C. The concentration range of the admixture in the test gas can be varied through several powers of ten and it is possible to modify the concentration within a few minutes. The invention also makes it possible to produce multiple component test gases directly from mixtures of chemical substances, and therefore provides a universally applicable method for producing test gases as defined above. |
