General description

LC-PAK® Polisher is a purification cartridge containing granular C18 reversed phase silica. It is validated to achieve water quality suitable for trace and ultra-trace organic analyses.
The compact device provides efficient and convenient access to freshly purified ultrapure water from the point of dispense of compatible water purification systems.

Application

Ultrapure water treated by an LC-Pak® polisher is suitable for eluent, buffer and blank preparation, sample dilution and standard preparation in HPLC, UHPLC, LC-MS and LC-MS-MS analyses.

Features and Benefits

  • Manufactured in an ISO 9001-compliant plant.
  • C18 granular silica in the polypropylene housing is tightly packed by a compression disc to avoid any channeling effect. This ensures that water passing through the LC-Pak® polisher is in close contact with the C18 chains binding organic molecules by hydrophobic interactions.
  • Produces a minimum of 500 L of water suitable for trace and ultra-trace organic analysis, when fed with Milli-Q® ultrapure water.
  • Care-free maintenance: the polisher is easily fitted and replaced.
  • LC-Pak® Cartridge is delivered hermetically sealed, with a Certificate of Quality
  • Activate with high-grade methanol before use.

  1. How frequently do the various consumables need to be changed?

    The frequency that consumables must be changed depends on the system's usage (treated water volume) and on the consumables themselves (time of usage). In order to ensure the quality of water and your results, the consumables should be replaced when the system alerts you.

  2. What is the consumables delivery time?

    Refer to the consumable's Product page for a first estimation of its expected delivery time and contact customer service for more information.

  3. How are consumables changed?

    To help you to change your system's consumables, several video tutorials are available on our YouTube channel: Milli-Q®System Care Tutorials. For high-flow systems, please keep in mind that all consumable changes must be approved by a 3-digit code that only the person in charge of the system knows.

  4. What is the shelf life for Filter?

    The shelf life is 2 years for all consumables kept in the recommended storage conditions (temperatures from 5 to 30°C; humidity between 10 and 80%). Contact your local representative for more information.

  5. Can I arrange to have my consumables automatically ordered and delivered once a year?

    It's possible to place only one consumable order per year with a specific contract called "Consumable Supply Agreement (CSA)" For further information, contact your local representative or sales contact.

  6. Where can I find data sheets, Certificates of Origin, Certificates of Analysis, and Certificates of Quality?

    Documents and certificates are available in the "Documentation" section on this page. Do not hesitate to contact us if you require further information.

  7. What steps are you taking towards improved sustainability?

    Sustainability is at the heart of our innovations. From reducing water and energy consumption, to minimizing plastic and chemical waste, our dedicated water system engineers are constantly working on new ways to reduce the ecological footprint of our products to better support the sustainability goals we’re all striving towards. For more information, we invite you to review the following brochure and infographic which highlight our efforts and achievements: link. Do not hesitate to contact your local representative for further information.

  8. How can I know which consumables can be used with my system?

    To know which consumables can be used on your system, you can see in the user manual of you system or see it on the following webpage of consumables. All the consumables for each system are indicated.

  9. If I have a final filter that I use only occasionally (e.g., Biopak®) and have another filter (e.g. Millipak®) that I most of the time, can I keep the 'occasional-use' filter for use again at a later time?

    It is not possible to re-use a filter that has been used and then removed because air intake during replacement creates an airlock and blocks water passing through the filter. If you regularly need two different filters, we recommend using two POD dispensers.

  10. Can consumables be opened and refilled?

    Unfortunately, this is not possible because of safety issues and the need to guarantee the quality of consumables and their interior purification components. Our consumables are manufactured in an ISO 9001-certified facility France in agreement with high quality standards.
