“…Gases in air may be sampled similarly when the desired constituent reacts chemically with impregnated filter paper -e.g., parts per billion of hydrogen fluoride (45) and parts per million of hydrogen sulfide (180). Aerosol particles in air may be collected by a high velocity impactor on an impregnated film (95).…”

The high cost of quantitative analyses, together with the ever-increasing demand for more quantitative data both in laboratories and plants, has continued to accelerate the development of automatic methods. This review covers the two years which have elapsed since the last in this series (187, 188). Competition in electronic instruments for measuring physical properties has led to a sometimes bewildering array of choices in how best to solve a particular analytical problem. Perhaps the most significant developments during this time have been the wider use of the recently developed electronic tools such as spectrophotometers, refractometers, titrators, electronic balances, and radioactivity detectors. However, a much needed emphasis on new techniques of sampling (collecting, measuring, and treating) and of separation has also evolved.

“…An analyzer-recorder which measures the darkening of a transparent 16-mm. motion picture film coated with a buffered lead acetate film, as the hydrogen sulfide in air comes in contact with it, has been used to determine up to 100 p.p.m. of hydrogen sulfide (466). An instrument employing a microscope and a photovoltaic cell was used to determine sulfuric acid aerosols.…”

In dcr Literatur sind viele Methoden fur die Bestimmung von Schwefelwasserstoff 2-4) und Schwefelkohlenstoff 7)") in Gasen beschrieben worden. Alle Methoden bestimmen diesc zwei Komponenten nach getrennten Verfahren. In der vorliegenden Arbeit beschreiben wir eine Methode, die es gestattet, Schwefelwasserstoff und Schwefelkohlenstoff in methylalkoholischer Kalilauge zu absorbieren und nebeneinander spektrophotometrisch auszuwerten.Bei der Absorption von Schwefelwasserstoff und Schwefelkohlenstoff setzen sich dies, Produkte nach den bekannten Gleichungen 1 und 2 urn.C,S,+CH,OH+ KOH = CH,0CS2K+H,0(1)Die Komponenten KOH und KHS der Gleichung 2 stehen noch miteinander
