Xtimate HPLC
Xtimate is a new premium HPLC column series and is the product of several years of continuous research on advanced surface modification at Welch Materials. The Xtimate Series includes columns based on hybrid silica-polymer packing materials and those based on pure polymer media, as well as size exclusion (SEC) columns.
Filter OptionsXtimate HPLC columns derive its outstanding performance from a special hybrid particle based technique, which coats a unique 5nm organic/inorganic polymer layer on the silica surface, so that the pH range is extended to 1.0-12.5. Xtimate column is designed for HPLC method development. Regardless of the types of mobile phase or high temperature, Xtimate HPLC columns always have stable performance and long lifetimes.
