Pharmaceutical
Faster Sample Throughput on a 1.9μm Pinnacle™ DB HPLC Column
By Rick Lake, Pharmaceutical Innovations Chemist, Randy Romesberg, HPLC Innovations Chemist, and Becky Wittrig, Ph.D., HPLC Product Marketing Manager
• Faster analyses, uncompromised chromatography using a 1.9μm Pinnacle™ DB column.
• Narrow particle size distribution ensures consistent, high efficiencies and longer column lifetimes.
• 100% Restek manufactured–from base silica to final packed column–assures quality and reliability.
Restek is pleased to introduce an exciting new addition to our family of HPLC columns–the 1.9μm
Pinnacle™ DB small particle column. Intended for use in ultra-high pressure liquid separations, the
1.9μm Pinnacle™ DB column combines the benefits of a popular technique with the unmatched
quality you expect from Restek. From the manufacturing of the base silica through the packing of the
column, Restek performs and tightly controls every step in the manufacturing process, guaranteeing
ruggedness and reliability. Here we discuss how and why small particle HPLC columns provide faster
separations, and demonstrate the high efficiency, excellent peak symmetry, and rapid analysis times
that can be achieved on the 1.9μm Pinnacle™ DB column.
