MS Optimised Microbore and Analytical LC Columns 

ACE UltraCore SuperC18 has been specifically designed for demanding MS application work and is based on high efficiency, low back pressure solid-core particles with unique Encapsulated Bonding Technology (EBT). This technology dramatically increases ligand coverage on the solid-core silica surface and consequently provides a number of key advantages for MS users. ACE UltraCore SuperC18 columns deliver extremely efficient, highly symmetrical peak shapes, which in turn ensure improved MS signal intensity. The SuperC18 bonded phase is highly resistant to hydrolysis and hence contributes minimal background bleed, maximising MS response and intensity. Furthermore, the Encapsulated Bonding Technology also enables ACE SuperC18 columns to be routinely used with MS compatible buffers across an extended pH range of 1.5 to 11. This allows chromatographers to adjust eluent conditions to maximise both resolution and MS signal response. ACE UltraCore SuperC18 columns are available in microbore 0.5mm and 1.0mm i.d. columns and analytical 2.1mm and 4.6mm i.d. columns. A wide range of lengths from 20mm to 250mm is available. ACE UltraCore is also available with SuperPhenylHexyl bonding. For further information on any ACE product contact [email protected] or www.ace-hplc.com.
