一般描述

VOC-Pak®精制器用于在1型水净化系统分配点的最终净化步骤中净化超纯水。它是一种活性炭滤芯，专门用于有效去除超纯水中的挥发性有机化合物（VOC）。

VOC是引起健康和安全问题的环境污染物，需要在水、土壤、气体和空气样品中进行常规分析。许多国家的不同监管机构已经制定了饮用水中VOC的质量标准。
因此，VOC-Pak®精制器是需要无VOC超纯水用于分析应用的研究员的绝佳选择。

应用

VOC-Pak精制器用于生产不含VOC的水，当通过超纯水系统进料时，通过GC和GC-MS分析水中的VOC。

不含VOC的水适用于玻璃器皿冲洗、空白、试剂、样品制备、标准品溶液或这些物质分析中的稀释液或VOC可能干扰的研究。它可用于纳米颗粒传感器和纳米电极的开发。

特点和优势

  • 经验证可生产300 L不含VOC的超纯水。
  • 易于维护：精制器易于安装和更换。
  • 重新设计底部尖端以安全安装防护罩。
  • 用于RFID与Q-POD®分配器连接的E-Sure标签可实现完全可追溯性（数据管理）和POD′s触摸屏接口上的自动耗材状态监控。
  • 在线提供质量证书。
  • 提供适合VOC分析的水保证：空白和标准品制备；玻璃器皿清洗；和样品溶解（如果在水以外的基质中分析VOC，即在土壤中）。

  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.
