LC-Pak
Recent advances in analytical techniques such as UPLC,
LC-MS, LC-MS / MS have considerably improved the sensitivity of organic and
biochemical molecules detection. As a result, these techniques require now
improved water quality for the production of mobile phase, buffers, blanks,
standards preparation, sample dilution, glassware rinsing or extraction.
Although fresh Milli-Q water quality has remained so far adequate for
most procedures involving these advanced techniques, a need has recently
appeared for higher water quality in some advanced applications.
To
answer this emerging need, Millipore has developed a new POD-Pak designed to
produce ultrapure water with an organics contamination level below most water
sources available today, at a fraction of the cost.
The LC-Pak can
be connected to the outlet of existing and new Millipore Type 1 water systems
(Milli-Q, Direct-Q, Synergy and Simplicity) producing ultrapure water with a
TOC level below 5 ppb, in order to deliver at least 500 L of ultrapure water
with minimum trace organic contamination, using as a purification media the
well known C18 reverse phase silica to remove traces of organics.
The LC-Pak is designed to provide scientists with the certitude that the
ultrapure water that they are using in critical organic molecules analysis at
trace and ultra-trace levels will be adequate.
The granular C18
reverse phase silica in the polypropylene housing is tightly packed by a
compression disc to avoid any channeling effect. This ensures that the water
passing through the LC-Pak will be in close contact with the C18 chains binding
organic molecules by hydrophobic interactions.
