Applications:


Separation of Propylparaben sodium on Newcrom R1 HPLC column

Propylparaben sodium can be analyzed by this reverse phase (RP) HPLC method with simple conditions. The mobile phase contains an acetonitrile (MeCN), water, and phosphoric acid. For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid. Smaller 3 µm particles columns available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation impurities in preparative separation. It also suitable for pharmacokinetics.

HPLC Separation of Mixture of Carbocisteine, Methylparaben & Propylparaben on Primesep 100 Column
Carbocysteine is a medication that reduces the viscosity of mucus making it easier to cough up. Methylparaben and propylparaben are used as preservatives in cosmetics, pharmaceuticals and food. They can be separated in HPLC on a Primesep 100 mixed-mode column by both hydrophobic and ionic properties present on the stationary phase. The analytical method uses acetonitrile (ACN) gradient and water with sulfuric acid (H2SO4) as buffer and UV detected at 200nm.

Condition

Column Primesep 100, 4.6x150 mm, 5 µm, 100A
Mobile Phase Gradient MeCN  - 2-50%, 20 min
Buffer H2SO4 - 0.05 %
Flow Rate 1.0 ml/min
Detection UV, 200 nm
