CLIPEUS - A Small Shield for a Big Job

Transcription

1 CLIPEUS - A Small Shield Virgil s Aeneid gave us a sanguine account of the problems encountered when working without a Clipeus a small shield popularized by the Romans. While arguably a less painful experience, chromatographers 2,000 years later still struggle when they work with inadequately shielded HPLC columns that are the by product of flawed end-capping technology. Higgins Analytical places a great deal of emphasis on effective silanol end-capping techniques. The bulky size and secondary chemical functionality of the end-capping moiety on TARGA (a large shield) HPLC columns and cartridges make them popular choices for researchers developing powerful LC/MS techniques or chromatographers doing routine analysis of difficult polar compounds.

CLIPEUS columns have Higgins Analytical s characteristically high lot-to-lot reproducibility because our carefully controlled reaction of monofunctional silanes can be driven to completion in a reproducible manner. This unbuffered Pyridine and Phenol chromatogram illustrates the absence of any undesirable solute/silanol interaction on a CLIPEUS C18 HPLC Column. Applications The high purity base silica and thoroughly end capped bonded phases insure that CLIPEUS columns and cartridges will perform well in demanding situations where many other column brands fail. Even polar compounds elute as sharp and symmetrical peaks permitting surprisingly short columns to be used for high speed analysis. In addition to C8 and C18 phases, CLIPEUS columns are available with phenyl or cyano functionality. CLIPEUS C18 5µm 150x4.6mm 40% MeOH/water (unbuffered) 1mL/min, 25ºC, 254nm P/N HC185-CS1546

2 CLIPEUS CLIPEUS Offers a Wide Range of Hydrophobicity The highly pure silica backbone and the thorough end-capping process that are characteristics of CLIPEUS HPLC columns enable a wide choice of column selectivity without compromising chromatographic performance. Not only do the columns with relatively small cyano and phenyl functional groups perform as efficiently as do the longer chain C8 and C18 versions of CLIPEUS, they also produce symmetrical peaks for acidic and basic analytes. This is usually not the case for these types of columns from most HPLC column manufacturers. The four CLIPEUS chemistry offerings and the wide variety of column and cartridge formats, with internal diameters ranging more than two orders of magnitude, present a powerful selection to a chromatographer desiring to optimize a difficult separation or to maximize the speed of a high throughput application.
