tetracycline or ciclopirox form tailing peaks in the presence of metal in the column/ system (see Figure 2).

Fundamental to the new ProteCol™ line of To address this potential risk, SGE’s ProteCol™ column development has focused exclusively on the most inert C8 and C18 phases in a variety of pore and particle sizes in the most inert column hardwares – glass lined, PEEK™ lined stainless steel (see Figure 3) and PEEKsil™.

Why Focus on Reversed Phase and Pore Size?
Reversed phase chromatography is by far the most commonly used form of liquid chromatography and most chromatographers prefer to stay in the reversed phase environment rather than move into other less conventional buffer systems.

What is often not considered is the role Alkane modified silicas were developed in the 1970s and because of the better resolution and higher reproducibility, quickly became the most popular separation technique in liquid chromatography. Since the elution conditions and elution order are opposite to what was “normal” chromatography, the term “reversed” phase was coined and has remained the general term describing a hydrophobic bonded stationary phase. When it comes to considering the optimal reversed phase column for the separation of a target analyte, the majority of liquid chromatographers base their selection on the type of bonded phase (C18, C8, C4, Phenyl etc), whether the column is end capped and the overall carbon loading.
