Uncertainty determination in measurements using a Gerdien Tube

Popis výsledku v původním jazyce

Light negative air ions demonstrably exhibit positive influence on the human organism. The concentration of these ions can be effectively used as the integral criterion for the evaluation of air purity, and there also exists a multitude of other applications. The presented aspiration method enables us to establish the concentration of air ions in the atmosphere. In a Gerdien tube fitted with a one-piece inner electrode, measurement of the saturation characteristics must be performed to facilitate the determination of the air ion mobility spectrum. This method is very sensitivity to noise and leakage current. In this paper is determination uncertainty of type B in Gerdien tube and electrometric amplifier. This uncertainty dependent to input bias current and input noise current used operational amplifier. The next significant source uncertainty type of B is temperature and time unstability quality Teflon insulator. The uncertainty of type A was tested in reference measurement in shielding camber. The result this paper is determine main source of systematic error and estimation uncertainty of type C for our Gerdien Tube.
