| The Milli-Q Reference A+ system brings you all the benefi ts of
the regular Milli-Q Reference system, plus additional analytical
precision: an indication of the TOC value of the product water.
Much in the way that resistivity measurement ensures that ionic
traces in ultrapure water are below the μg/L level, the TOC Indicator
warrants that organic contamination in the ultrapure product
water is below the 5 ppb limit of the Milli-Q Reference A+ system’s
water specifi cation. This is especially important for the numerous
applications that are sensitive to organic contaminants—including
the very common analytical technique, HPLC (High Performance
Liquid Chromatography).
Millipore’s patented on-line TOC monitoring method is wellcorrelated with the A10® monitor’s low TOC range monitoring (1 to 10 ppb), and is able to detect any signifi cant organic contamination increase in the water produced. Users can therefore be assured that the organic contamination level of the ultrapure water produced by their Milli-Q Reference A+ systems is within specifications. * Total Oxidizable Carbon Click the PDF above for the full document. | |
