Abstract

En fremgangsmåte for å ta stikkprøver og bestemme tilstede- værelse av visse rester av forurensninger i beholdere (C) omfatter trinn hvor komprimert luft sprøytes inn i nevnte beholdere i den hensikt å fortrenge i det minste en del av deres innhold, en stikkprøve på det således fortrengte beholderinnhold suges ut ved utøvelse av en sugekraft på det og den utsugede stikkprøve analyseres for å bestemme nærvær eller fravær av visse rester i denne. Den komprimerte luft sprøytes gjennom et munnstykke (16) inn i en åpning i be- holderne (C) for å fortrenge en del av beholderinnholdet og danne en stikkprøvesky (18) utenfor vedkommende beholder. Stikkprøveskyen suges så i det minste delvis ut ved hjelp av en sugekraft og stikkprøven analyseres med hensyn til nærvær av forurensninger, slik som nitrogenholdige forbindelser eller hydrokarboner. I en utførelse avledes ca. 90 % av den utsugede stikkprøve fra analysatoren (26) og resirkuleres inn i luftinjektoren (14). Et vidt omfang av potensielle for- urensninger kan påvises dersom drikkevareflaskene lagres uten kapsel før undersøkelsen, slik at flyktigheter av drikkevare- produkter får tilstrekkelig tid til å spre seg.A method of sampling and determining the presence of certain residues of contaminants in containers (C) comprises steps in which compressed air is injected into said containers for the purpose of displacing at least a portion of their contents, displaced container contents are sucked out by applying a suction force to it and the extracted sample is analyzed to determine the presence or absence of certain residues therein. The compressed air is injected through a nozzle (16) into an opening in the containers (C) to displace a portion of the container contents and form a sample cloud (18) outside the container in question. The sample cloud is then at least partially extracted by a suction force and the sample is analyzed for the presence of contaminants, such as nitrogenous compounds or hydrocarbons. In one embodiment, approx. 90% of the extracted sample from the analyzer (26) and recirculated into the air injector (14). A wide range of potential contaminants can be detected if the beverage bottles are stored without a capsule prior to the investigation, so that beverages of beverage products are allowed sufficient time to disperse.
