Pharmacopoeias describe standards for biological substances and pharmaceuticals as well as methods for testing drugs. Those standards and of course the demand of the analysis reliability require a regular validation of the analysis systems used in pharmaceutical laboratories. The WinASPECT PLUS validation software for the UV/Vis spectrophotometer SPECORD® PLUS offers the user to perform a validation comfortably on his own or have it done by a service specialist. Parameters like photometric accuracy in UV and Vis range, wavelength accuracy and reproducibility, stray light and resolution can be selected with one mouse click. The WinASPECT PLUS validation software provides a fully automatic monitoring of the accuracy of the measurement and a set of documentation masters to draw up a GLP (Good Laboratory Practice) conforming documentation of the validation results. An additional installation and operation qualification (IQ/OQ) guarantees the highest degree of reliability of the measurement results.
