On-line computers in classical chemical analyse

Abstract

Developments in digital electronics enable classical chemical analysis to regain some of the terrain lost to instrumental techniques. In chemical analysis, computerization can provide higher precision, higher speed and lower costs. The value of interactive systems in routine work is emphasized.

Resonant frequency measurements as an alternative to phase-selective A.C. polarography in tensammetry and pseudocapacitance determinations

“…Accuracy in the current measurements is the only important requirement. A drawback of the method presented earlier [4] is that in the presence of electroactive compounds broad pseudocapacitance peaks occur that prohibit tensammetric determinations in a certain potential range around their respective standard potentials.…”
