Clariant Chemicals India uses Metrohm Ion Chromatography to Test for Chromium(VI).
Jul 26 2011
Clariant Chemicals India Ltd is a subsidiary of the Swiss multinational corporation Clariant and specialises in the manufacture of dyestuffs and other chemicals for the leather, textile and other industries. At their production facilities in Thane near Mumbai they have been working with Metrohm instrumentation for years.
At one time, Dr Dileep Wakankar, VP Corporate Product Safety, had to analyse the dyestuff in a batch of several thousand pairs of shoes for toxic chromium(VI). The job proved tricky as the standard methods (photometric detection) failed to yield correct results because the dyestuffs reacted unpredictably during the analysis. While scouting for a suitable method Dr Wakankar came across ion chromatography and Metrohm. Using a Metrohm IC system and being supported by the professionals of Metrohm India, Dr akankar was finally able to prove that the suspected dyestuffs did in fact not contain any chromium(VI). “What was really unique was that these people understood my requirements very well,” said Dr Wakankar, “They cooperated with me, and out of partnership resulted an established relationship, which is lasting even today”. Just like all other Metrohm customers, Dr Wakankar can rely on the unique know-how and experience of Metrohm’s engineers and application chemists.
