General description

Purospher® STAR RP-18 endcapped, 5 µm HPLC columns are designed for universal use and allow the separation of basic, neutral, and metal chelating compounds with simple mobile phases and excellent peak symmetry. They are based on ultra-pure fully porous silica particles (Type B). These columns offer an outstanding stability from pH 1.5 to 10.5 over a wide temperature range, and suitability for up to 100% aqueous mobile phases. Plus, they demonstrate best all-round retention characteristics, as proven by the Tanaka test. Thanks to these features, Purospher® STAR RP-18 endcapped, 5 µm HPLC columns allow maximum flexibility to use the best chromatographic conditions for any separation including reversed phase.Purospher® STAR RP-18 endcapped, 5 µm LiChroCART™ 250-4 is a cartridge column which requires a manuCART™ cartridge column holder part number 1.51486.0001. The manuCART™ can be used to hold one cartridge column with or without direct integration of a 4-4 mm guard column. The recommended guard column is Purospher® STAR RP-18 endcapped (5 µm) LiChroCART™ 4-4 part number 1.50250.0001. LiChroCART™ cartridge columns mounted with a manuCART™ cartridge column holder are hand-tight only and have therefore a maximum pressure stability of 250 bar. For higher pressure stability requirements Purospher® STAR RP-18 endcapped, 5 µm Hibar® RT 250-4 HPLC columns are available part number 1.150037.0001.The column dimension of 250 mm length x 4 mm I.D. is the optimal choice for high resolution HPLC separation of complex samples.Item 1.50252.1003 is a Validation kit containing 3 Purospher® STAR RP-18 endcapped, 5 µm LiChroCART™ 250-4 cartridge columns from 3 different base material lots.Learn more about Purospher® STAR HPLC and UHPLC ColumnsLearn more about the Supelco HPLC Column portfolio and Method development:Brochure: HPLC and UHPLC Column Selection GuideBrochure: A Practical Guide to HPLC - Method Development Guide

Questions

1–2 of 2 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
