Ultisil Amino Acid

by Welch Materials

Our Ultisil Amino Acid HPLC columns are made from spherical, totally porous, and ultra high purity (>99.999%) type B silica particles. Our proprietary surface modification before bonding generates a very smooth and uniform surface with less acidic surface silanol. Ultisil Amino Acid columns provide the best performance in peak shape, efﬁ ciency and resolution for the analysis of 18 amino acids. Total sample preparing time can be achieved in as little as 30 min.

How similarity is calculated

Eligible families receive a weighted score from Modification (25%), Product Usage (20%), Carbon Load (15%), Endcapping (10%), Pore Size (10%), Surface Area (8%), pH Stability (8%) and Particle Size (4%). The score uses data available in both families and requires at least three comparable criteria, at least 50% data coverage and a minimum 55% score. A relevant active sponsor may appear first and is always labelled Sponsored.

A similarity score does not guarantee identical selectivity or performance. Confirm suitability under the intended method conditions.
