The article presents a fast screening method for beta blockers by high-performance liquid chromatography (HPLC) with agilent poroshell 120 columns. It states that beta blockers can be abused in sports involving little physical activity such as archery which reduces cardiac contraction, heart rate, and coronary blood flow. It showed that phenyl-hexyl phase has unique reversed-phase selectivity for polar aromatics and heterocyclic compounds.

The article focuses on the use of Poroshell HPH-C18 columns at elevated pH as a tool for method development which is made by the equipment maker Agilent Technologies Inc. Topics discussed include pH can be used to adjust selectivity without losing column lifetime at elevated pH conditions, acid, base and neutral compounds chromatographic resolution, use of the column in ammonium bicarbonate and the analytes that remain at the same retention time.

The article offers information on the screening of steroids with the help of high-performance liquid chromatography technique which uses Poroshell 120 columns from Agilent. It mentions that short column length and high efficiency reduces the analysis time and allows rapid equilibration. It presents a figure which shows the chromatogram of estrone, progesterone and testosterone.

The article discusses a pharmaceutical testing of Naproxen tablets applying United States Pharmacopeia compendia analysis with liquid chromatography (LC) columns. During the testing, Poroshell LC 120 columns which are claimed can provide improved performance on a typical LC instrument, have been used. It concludes that laboratories performing compendia analysis with LC columns can benefit from the increased speed, resolution, and sensitivity provided by Poroshell 120 columns.
