Mercury vapour standard concentration ng/ml

Description

J E Patterson - jepspectro.com - version 20150905

A good calibration curve can be obtained using a simplified Dumarey equation - Reference: R. Dumarey, E. Temmerman, R. Dams, J. Hoste, Analyt. Chim. Acta 170, 337 (1985).

Enter temperature in °C of mercury calibration vessel into A

The mercury vapour concentration in air is displayed in ng/ml

The equation is Hg ng/ml = 10^(-3229/(T+273.16)+14.6 - Log(T +273.16))
