Millipore LC-Pak
The LC-Pak polisher provides ultrapure water with a very low level of organics
Although industry standard Milli-Q water has long been a satisfactory solution for these advanced techniques, recent developments have increased the sensitivity of organic and biochemical molecule detection. As a result, chromatographers increasingly need higher quality ultrapure water for use in mobile phase, buffers, blanks and standards, as well as for sample dilution, glassware rinsing and extraction. Millipore says the LC-Pak cartridge provides ultrapure water with a very low level of organics at a fraction of the cost of commercially available bottled water for chromatography.
The LC-Pak 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 or any Millipore Type I water purification system. The cartridge produces at least 500 litres of ultrapure water suitable for trace organics analysis when fed with ultrapure water with a TOC level below 5ppb.
“We put the LC-Pak cartridge through an extensive validation process,” said Millipore lab water group product manager Jean-François Pilette. “Results showed that water produced with the Milli-Q/LC-Pak combination matched or exceeded the quality of commercially-available water.” Details of this study are provided in the LC-Pak Validation Guide, which can be found by clicking on the link below.
