We see from your search that you're looking for information on the term "Deionised Water", and we have a large number of manufacturers' news releases and technical articles here on Laboratorytalk which will be of interest. Let me be your guide.
 
Start with the news release Rancimat method saves time evaluating antioxidants from Metrohm UK, which we summarised at the time by saying "The 743 Rancimat instrument from Metrohm UK is designed to evaluate the effects of antioxidants on edible oils and food products containing oils and fats". A couple of weeks before, we featured the news release Compact ion chromatograph aids fertiliser analysis from Metrohm UK: "Nitrogen and Phosphorus are both present in fertilisers and these can easily and affordably be analysed as nitrate and phosphate using Metrohm's Compact IC systems".
 
In June 2007, we covered the news from Metrohm UK concerning its Application bulletins 204 and 141 - take a look at Application monographs on edible oils analysis which says: "The Rancimat method is considerably less costly, less labour-intensive but as accurate as the traditional active oxygen method (AOM) for the oxidation stability index (OSI) of natural fats and oils".
 
Take a look also at the news release from Metrohm UK, Cheaper QA analysis of sugars in chocolate bars, as well as Aquatrode Plus for highest level water analysis from Metrohm UK, and Analysis of sugars in chocolate bars from Metrohm UK.
