TOC INDICATOR CONCEPT AND BENEFITS
The
Milli-Q® Reference A+ system
brings you all the
benefits 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 specification.
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).
Merck Millipore’s patented on-line TOC monitoring
method is well correlated with the A10® monitor’s low
TOC range monitoring (1 to 10 ppb), and is able to detect
any significant 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.
