"Application Of Flow Injection Potentiometry To The Determination Of Chloride In Various Matrices"
Fresenius J. Anal. Chem. 1989 Volume 335, Issue 8 Pages 931-937
Wolfgang Frenzel

Abstract: Chloride-selective electrodes were prepared from silver tubes (1 cm x 0.3 to 1.0 mm i.d.); the inner wall was coated with AgCl. Behaviour under steady-state and flow injection conditions was studied and the influence of system parameters on sensitivity, detection limit, response time and sample throughput was discussed. Sample throughput was 60 to 200 h-1. The calibration graph was rectilinear from 0.1 to 10,000 mg L-1 of Cl-, with a detection limit of 0.01 mg L-1 and a coefficient of variation of 1%. The method was applied in the analysis of tap and mineral water, emission control of HCl and the determination of Cl- in silicon nitride.

"Contamination By Heavy Metals In Reactive Process Gases"
Fresenius J. Anal. Chem. 1992 Volume 343, Issue 9-10 Pages 727-732
Jürgen Schram

Abstract: Using the determination of Fe in gaseous HCl as a model system different analytical systems are discussed for the cited determination. Methods based on impinger systems and continuous-flow systems are considered as are direct infeed methods (details and schematics given). The advantages and disadvantages of the systems are outlined.
