The Novel Triazole Bonded HILIC Column
Nacalai Tesque (JAPAN) introduces COSMOSIL HILIC for hydrophilic interaction chromatography. This novel triazole bonded silica stationary phase provides higher polarity than non-modified silica columns, resulting in stronger hydrophilic interactions. The positively charged triazole stationary phase also offers an anion- exchange mechanism, enabling the strong retention of acidic compounds.
The COSMOSIL HILIC Chromatogram Index, which includes 167 chromatograms using COSMOSIL HILIC, is available on the Nacalai Tesque website. This index is a useful tool for all chromatographers, assisting them to optimise analytical conditions for hydrophilic interaction chromatography.

nacalai.com Online Interactive Tool Enables Fast Selection of LC Column Protection
Phenomenex Inc introduces Guard Finder, an interactive online tool that helps users quickly select column protection products for over 41,000 HPLC, UHPLC and preparative HPLC columns. The easy and flexible interface allows the customer to search by brand, part number, technique or column phase. In just seconds, the tool matches input with the recommended Phenomenex column protection.
The Guard Finder tool recommends column filters and SecurityGuard™ cartridges that protect against the damaging effects of chemical contaminants and microparticulates introduced by the sample, mobile phase or system, which can negatively impact column lifetime, method sensitivity,
quantitation and peak identification. Column protection also reduces troubleshooting and downtime.
“Before we created this online tool, the process of choosing column filtration and protection systems was manual and laborious,” explained J.T. Presley, Brand Manager for Phenomenex. “Guard Finder was specifically designed to save customers time and ensure they get the most out of their columns.”
