ULBON HR-52, 5% Phenylmethyl silicone, 0.50 μm

The ULBON HR series consists of ten types of stationary phases designed for general analyses and a wide range of specialized analytical purposes. We also stock columns with a variety of lengths, inner diameters, and stationary phase film thicknesses in order to meet your requirements.

Features
●Highly inert inner surfaces of columns enable high precision quantitative analyses.
●Adsorption points on the inner surfaces of columns have been completely removed through thorough processing. As a result, free acids and amines, which are easily adsorbed, are eluted without interactions with active surfaces.
●No exfoliation and bleeding of stationary phases enabling high sensitivity analyses.
●In HR series columns, stationary phases are firmly chemically bonded to surfaces resulting in almost no exfoliation and bleeding of stationary phases. This enables high sensitivity analyses.
●Maximum operating temperatures higher than those of ordinary WCOT columns.
●In comparison with WCOT columns, maximum operating temperatures are approximately 70°C higher for this series (chemically bonded columns). The maximum operating temperature for the HR-20M (corresponds to PEG-20M) series is 240°C, while that for HR silicone series columns is 330°C (except HR-1701 and HR-16 columns).
