Millipore has introduced the LC-Pak point-of-use polisher, which provides fresh, ultra-pure water with low traces of organics for analytical techniques such as UPLC, IC-MS and LC-MS/MS.
Chromatographers increasingly need higher-quality ultra-pure water for use in mobile phase, buffers, blanks and standards, as well as for sample dilution, glassware rinsing, and extraction.
The LC-Pak cartridge is said to provide ultra-pure water with a low level of organics at a fraction of the cost of commercially available bottled water for chromatography.
The LC-Pak cartridge contains tightly packed C18 reverse-phase silica that binds organic molecules through hydrophobic interactions.
It is easily connected to the outlet of a Milli-Q water dispenser (Q-POD) or any Millipore Type I water-purification system (Milli-Q, Direct-Q, Synergy or Simplicity).
The cartridge produces at least 500L of ultra-pure water suitable for trace organics analysis when fed with ultra-pure water with a TOC level below 5ppb.
The LC-Pak cartridge is the latest addition to Millipore's suite of application-specific point-of-use polishers.
