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. The invention relates to a method for analytical Determination of organic substances in a low concentration tion by mass analysis, the substances from one High pressure reservoir in the mass analyzer with lower pressure to be transferred.

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. The object underlying the invention is in that e.g. Process as well as the plant such szugestalten that also substances in the ppb to ppt range are present, can be directly verified by mass analysis can.

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. The solution is characterized in that
a) the storage container is connected directly to the mass analyzer via a metering device,
b) the mass analyzer is pumped out to pressure ranges below its normal operating conditions and thus the concentration of the substances is reduced, and
c) the detection of substances with increased sensitivity is carried out.

Die Erfindung eignet sich insbesondere zur Bestimmung der Photostabilität leicht flüchtiger organischer Verbin­ dungen (z.B. Umweltchemikalien, Konzentration-/Zeit­ diagramme, Halbwertzeiten, Reaktionsgeschwindigkeitskon­ stanten). The invention is particularly suitable for determination the photostability of volatile organic compound applications (e.g. environmental chemicals, concentration / time diagrams, half-lives, reaction rate con aunt).
