Measure organic substances in high
purity water
The A10 TOC Monitor can measure from 1 to 99ppb of organic substances in pure and ultrapure water at an hourly flow rate of up to 200l/hour
Millipore has announced a new A10 total oxidisable carbon (TOC) Monitor This cost-effective calibrated monitor is shipped with a certificate of calibration and is designed according to the requirements of the TOC Suitability Test in USP 643

A complete picture of water purity
Many applications are sensitive to organic impurities, which go undetected by resistivity measurements and which may cause adverse effects on results
Even relatively low TOC levels in purified water affect the outcome of many laboratory experiments.
Therefore, scientists need to regularly measure TOC levels in their high purity water.
Most Milli-Q water purification systems are designed with a built-in TOC monitor to ensure regular, on-line measurement of organic substances in the ultrapure water at the time of delivery.
The A10 TOC Monitor can be used on systems without built-in TOC monitors.
This stand-alone monitor can be connected to any high purity water laboratory system, providing rapid measurement of TOC levels in the water produced.
An accurate TOC measurement is important in applications such as chromatography, in which moderate TOC levels will degrade the baseline quality and reduce the sensitivity of analysis.
In addition, the presence of TOC will foul the chromatography column beads, preventing good mass transfer between the beads and the mobile phase and ultimately shortening the life of the column.
Undetermined levels of TOC in ultrapure water used to prepare culture media or buffers will affect experiments including cell culture or electrophoresis separations. Request a free brochure from Millipore ...
