Beta-Hydroxy beta-Methylbutyric acid (HMB) is used as an over-the-counter dietary supplement, which has been shown to increase lean body mass and muscle size. Another use for it is in to promote wound healing and to prevent the loss of muscle in individuals suffering from age-related muscle loss. HMB can be retained on a Primesep B mixed-mode column in in 3 minutes using low Acetonitrile (ACN) concentration in the mobile phase (10%) with 0.2% Phosphoric acid buffer. UV detection 200nm.

Application Column
Primesep B
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.
