Analysis of Irbesartan - an Example of Scaling USP Methods

8 Jul 2012

In this application note, the Irbesartan USP method is used as an example when transferring an HPLC method from one column dimension to another, from one sorbent particle size to another, or from one type of HPLC instrumentation to another. Four different conditions were evaluated, two within allowed changes, and two that would require complete revalidation (using a too short column, with too small particle size and not scaling the linear velocity accordingly).

Purospher® STAR HPLC and UHPLC columns

Merck KGaA, Darmstadt, Germany

The base silica of Purospher® STAR columns is 99.999 % pure. Furthermore, meticulous care is given to quality control over all aspects of silica structure and chemistry. The excellent converge of the surface and the purity of the material ensures excellent peak symmetry for acidic, basic and even for chelating compounds. Accurate results with excellent peak shape for all types of analytes Outstanding resolution due to high separation efficiency Proven reliability and reproducibility from run to run and batch to batch Universal compatibility with best all-round performance according to Tanaka Maximum flexibility in method development and choice of mobile phase pH stability from pH 1.5 – 10.5 Suitable for up to 100 % aqueous mobile phases Highest sensitivity and suitability for LC-MS applications

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.
