Advanced Chromatography Technologies is pleased to announce the launch of a range of ultra low dispersion, high quality pre-column filters, especially designed for UHPLC and HPLC applications.
One of the most common causes of LC column failure is particulate material collecting on the inlet frit of the column, causing high back pressure and/or distortion of peak shape. By one estimate, over 70% of LC column failures are caused by inlet frit plugging. UHPLC columns, especially those packed with sub-2μm size particles, are particularly vulnerable to inlet frit plugging. Advanced Chromatography Technologies offers three different ranges of pre-column filters, each designed for column specific protection...
