(DE) AUTOMATISCHE BESTIMMUNG DER BELASTUNG VON WÄSSRIGEN REINIGUNGSLÖSUNGEN MIT KOHLENSTOFFHALTIGEN VERBINDUNGEN

Abstract
(DE)
Verfahren zur automatischen Bestimmung des Gehalts einer wäßrigen Reinigungslösung an anorganisch und/oder organisch gebundenem Kohlenstoff, wobei man programmgesteuert a) aus der wäßrigen Reinigungslösung eine Probe mit einem vorgegebenen Volumen zieht, b) erwünschtenfalls die Probe von Feststoffen befreit und/oder homogenisiert, c) erwünschtenfalls die Probe in einem vorgegebenen oder als Ergebnis einer Vorbestimmung ermittelten Verhältnis mit Wasser verdünnt, d) den anorganisch und/oder organisch gebundenen Kohlenstoff mit an sich bekannten Verfahren bestimmt, e) das Ergebnis der Bestimmung an einen entfernten Ort überträgt und ausgibt und/oder auf einem Datenträger speichert und/oder als Basis für weitere Berechnungen heranzieht. Dabei ist eine programmgesteuerte oder extern anzustoßende automatische Überprüfung der Meßeinrichtung vorgesehen. Badpflegemaßnahmen können programmgesteuert oder auf externen Anstoß eingeleitet werden.
(EN)
The invention relates to a method for automatically determining the inorganically and/or organically bound carbon contained in an aqueous cleaning solution, comprising the following program-controlled steps: a) drawing a sample from the cleaning solution with a predetermined volume, b) optionally, liberating the sample from solids and/or homogenising the sample, c) optionally, diluting the sample with water according to a ratio which is predetermined or determined as a result of a preliminary determination, d) determining the inorganically and/or organically bound carbon using techniques known per se, e) transferring the result of the determination to a remote location and issuing it, and/or saving the result on a data support and/or using it as a basis for further calculations. The invention also provides a program-controlled or externally initiated automatic method for checking the measuring device. Measures for protecting the bath can be introduced in a program-controlled manner or by external initiation.
(FR)
L'invention concerne un procédé de détermination automatique de la teneur en carbone lié par voie inorganique et/ou organique, d'une solution nettoyante aqueuse. Ce procédé commandé par programme comprend les étapes suivantes: a) un échantillon de volume prédéfini est prélevé de la solution nettoyante aqueuse, b) le cas échéant, l'échantillon est libéré des solides qu'il contient et/ou homogénéisé, c) le cas échéant, l'échantillon est dilué avec de l'eau dans un rapport prédéfini ou déterminé comme résultat d'une prédétermination, d) le carbone lié par voie inorganique e/ou organique est déterminé avec des procédés connus en soi, e) le résultat de la détermination est transmis à un lieu éloigné et est sorti et/ou est mémorisé sur un support de données et/ou sert de base pour d'autres calculs. A cet effet, il est prévu un contrôle automatique commandé par programme ou à déclencher de manière extérieure, du dispositif de mesure. Des mesures de soins par bain peuvent être prises par commande par programme ou par déclenchement extérieur.
