Aegispak HPLC Column

To reduce the effects of metal impurities on silica gel, high-purity silica gel for chromatography was refined using a technology developed by our company.

The purified silica gel surface was coated with a silicone polymer using chemical vapor deposition (CVD) to create a hydrophobic surface (blocking the silanol) and then bonded with functional groups to synthesize the chromatographic resins. Additional end-capping reactions performed at high temperature and pressure minimize remaining silanol groups.

There is a slight difference in the separation pattern compared to the INNO (-Si-O-Si-R) resin, which bonds the functional group directly to the silicon polymer.

◈ Specification

◈ Product Description

- Aegispak Series

• ① Aegispak C18-F
  This column characterized by relatively low hydrophobic and low surface polarity.
  Effective in analyzing highly hydrophobic compounds quickly.(USP L1)
• ② Aegispak C18-L
  Column with high hydrophobicity and low surface polarity.
  This is a general-purpose column with moderate retention characteristics.
  In addition to polarizing compound analysis, hydrophobic compound analysis is highly utilized(USP L1)
• ③ Aegispak C8
  Column with low hydrophobicity and high surface polarity.
  Although analysis is possible at a faster time than C18, the difference in polarity between specimens is larger to facilitate separation.
  It is also useful for quick analysis, such as content testing of a single compound.(USP L7)
• ④ Aegispak Silica
  This column is filled with ultra-high purity silica gel that has been reconditioned for high purity silica gel.(USP L3)
