Abstract

Die Erfindung betrifft ein Verfahren und einen Testkit zum Nachweis von insbesondere freiem Sulfit in wässrigen Proben. Die Probe wird in ein verschliessbares Gefäss gegeben, bevorzugt mit Säure leicht angesäuert und mittels eines Teststreifens der Sulfit-Gehalt in der Gasphase oberhalb der Probe bestimmt. Die Auswertung kann visuell oder reflektometrisch erfolgen. Der erfindungsgemässe Testkit zur Durchführung des Verfahrens weist ein verschliessbares Gefäss und einen Teststreifen zur Sulfit-Analyse auf.
