    Description / Table of Contents: Zusammenfassung Es wird ein Verfahren zur simultanen gas-chromatographischen Bestimmung geringer Gehalte an Wasser, Wasserstoff, Sauerstoff und Stickstoff in gasförmigem oder flüssigem Ammoniak angegeben, das auch gelöste Salze enthalten darf. Die Gase werden an zwei hintereinander geschalteten Säulen, gefüllt mit Kohlenstoff-Molekularsieb und Silicat-Mokekularsieb, getrennt. Die Erfassungsgrenzen liegen bei 10 ppm (H2O), 12 ppm (H2), 5 ppm (O2) und 1ppm (N2).
    Notes: Summary A method was developed for the simultaneous gas-chromatographic determination of traces of water, hydrogen, oxygen, and nitrogen in gaseous or liquid ammonia which also may contain dissolved salts. The gases are separated on two consecutive columns filled with carbon molecular sieve and silica molecular sieve. Limits of detection are 10 ppm (H2O), 12 ppm (H2), 5 ppm (O2), and 1 ppm (N2).
