High-performance liquid chromatography (HPLC) is used for the routine evaluation of raw materials, active pharmaceutical ingredients (APIs) and finished products. Next to the determination of content and purity according to pharmacopoeial methods, the focus of this methodology is on validations, method developments and method transfers specifically tailored to customers' products. The detection methods available to our customers are diode array (DAD), UV/Vis, refractive index (RI), pulsed amperometric and fluorescence detectors.

In the field of gas chromatography (GC), our service portfolio comprises tests for residual solvents, content and purity testing on raw materials, APIs and finished products. In addition, we offer comprehensive method developments and validations as well as the transfer of your methods to Labor LS. In the field of gas chromatography (GC), we use gas chromatographs with headspace and liquid injection.

The electrophoretic methods we offer in the context of development, validation and transfer include gel-based tests (agarose gel electrophoresis, SDS PAGE, isoelectric focusing) according to pharmacopoeial methods or to your own requirements.
