InertSustain Amide LC Columns, HILIC Column

inertsustain Amide InertSustain Series
GL Sciences developed new Silica gel "Evolved Surface Silica” for InertSustain Series which provides both high inertness and high durability. Inert-and-sustainable InertSustain series HPLC columns are the latest models of GL Sciences and are recommended as the first choice for various purpose.

Comparison of Retention in Analysis of Melamines

Cyanuric acid and Melamine are very difficult to retain and separate in reversed phase column because the polarity is very high. However, if you use a column for HILIC like InertSustain Amide, there is no problem and separation is fine. InertSustain Amide is strong, and it shows that it is good for separating polar compounds.
