Abstract

Die Erfindung betrifft ein Verfahren zur analytischen Bestimmung von organischen Stoffen in geringer Konzentra­ tion mittels Massenanalyse, wobei die Stoffe aus einem Vorratsbehälter hohen Druckes in den Massenanalysator mit niedrigerem Druck zu überführen sind.
Die der Erfindung zugrundeliegende Aufgabe besteht darin, das e.g. Verfahren sowie die Anlage derart au­ szugestalten, daß auch Stoffe, die im ppb- bis ppt-Bereich vorliegen, direkt massenanalytisch nachgewiesen werden können.
Die Lösung ist dadurch gekennzeichnet, daß
a) der Vorratsbehälter über eine Dosiereinrichtung direkt mit dem Massenanalysator verbunden wird,
b) der Massenanalysator auf Druckbereiche unterhalb sein­ er normalen Betriebsbedingungen ausgepumpt und damit die Konzentration der Stoffe reduziert wird, und
c) der Nachweis der Stoffe mit erhöhter Empfindlichkeit durch-geführt wird.
Die Erfindung eignet sich insbesondere zur Bestimmung der Photostabilität leicht flüchtiger organischer Verbin­ dungen (z.B. Umweltchemikalien, Konzentration-/Zeit­ diagramme, Halbwertzeiten, Reaktionsgeschwindigkeitskon­ stanten).
