[Indicator tubes with a noncylindrical form for indicator packing]
Abstract:
A new type of system is made for determination of chemical pollutants in the air--indicator tubes with noncylindrical indicator filling--a subject of invention. The effect of the noncylindrical form on the metrological characteristics of the indicator tubes is studied. The noncylindrical filling is a way to influence these characteristics without changing the chemical receipt. There are a number of advantages: increasing more of 10x the sensitivity; linearization of the logarithmic characteristics of the indication dusts; possibility to lay two contrary scales on the conical indicator tubes for sucking respectively from the one or the other side of the asymmetric indicator filling, thus realising opportunities for defining of very low or very high accuracy. A new type of sampling system is established in practice. The dependences are given graphically.
