Supplier: MACHEREY-NAGEL

NucleoBond® Xtra Midi and Maxi kits contain enlarged columns which leads to lower silica resin beds. This in turn enables faster flow of lysate and buffers through the columns.

Supplier: Restek

General purpose Rt®-TCEP columns is ideal for aromatics and oxygenates in gasoline.

Supplier: Restek

Mid-to high-polarity phase, Crossbond® diphenyl dimethyl polysiloxane, general-purpose columns for phenols, fatty acids, triglycerides.

Supplier: Restek

Analyse active samples accurately; ideal for chlorinated pesticide analysis (reduces endrin breakdown to less than 1%)

Supplier: Restek

Separations of more than one hundred chiral compounds have been achieved using our unique DEX columns, and DEX columns continue to demonstrate stability after hundreds of temperature program cycles. By adding β or γ cyclodextrin to our bonded Rtx-1701 stationary phase, we greatly enhance overall utility and column lifetime for our chiral columns, compared to columns that have pure cyclodextrin stationary phases. 2,3-di-O-ethyl-6-O-tert-butyl dimethylsilyl beta cyclodextrin added into 14% cyanopropylphenyl/86% dimethyl polysiloxane

Ultra C8 is a conventional monomeric octylsilane column offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape. It is made of high-purity, type-B silica that minimises activity and creates high-density bonding. These columns are designed for selective and reliable HPLC applications.

Supplier: Restek

Ultra IBD is a polar-embedded column that acts as a strong hydrogen bonder and may be the most versatile column available today. It is compatible with 100% aqueous mobile phases and can be used under reversed-phase or HILIC conditions to retain very polar, ionic compounds in highly organic mobile phases.
