Ultra 1 and Ultra 2 columns are non polar. The Ultra 1 and Ultra 2 resemble the Hp-1 and Hp-5 with tighter specifications for retention index and capacity factors. The Ultra 1 and Ultra 2 are intended for use with the Sadtler Retention Index Library. Agilent makes more capillary columns than anyone else in the world and our commitment to product reliability and repeatability has raised the level of quality that chromatographers demand. We continue to tighten our performance criteria such as separation efficiency, retention characteristics, peak height ratios, and bleed rates.
