Separation type: Liquid Chromatography Mixed-mode
High Performance Liquid Chromatography (HPLC) Method for Analysis of Acetaminophen, Phenylephrine, and Ascorbic Acid
Acetaminophen (or paracetamol) is one of the most popular over-the-counter painkillers all over the world (in the US it is best known under the brand name Tylenol). Ascorbic acid (also known as Vitamin C) helps your body build up muscle, cartilage, and other important building blocks in your body. Phenylephrine is a common over-the-counter decongestant, but can also be used for pupil dilation and hemorrhoid treatment. While all of these compounds are available at your local pharmacy, Vitamin C intake can reduce the body’s ability to break down acetaminophen.
All three of these compounds can be measured at low UV. Using a Primsep S normal phase column and a mobile phase consisting of water and acetonitrile (MeCN) with an Ammonium acetate (AmAc) buffer, these three compounds can be separated and UV detected at 270 nm. Varying the buffer concentration changes the order in which phenylephrine and ascorbic acid are retained. This method is compatible with Mass Spectrometry.

Application Column
Primesep S2
The Primesep family of mixed-mode columns offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad array of chemical compounds across multiple applications. Corresponding Primesep guard columns, available with all stationary phases, do not require holders. SIELC provides a method development service available to all customers.
