Validation is not an easy task. It is an ongoing complex process that evaluates the entire, sample specific process, products and analytical methods.
Validation is not an easy task. It is an ongoing complex process that evaluates the entire, sample specific process, products and analytical methods and consists of four qualification phases: Design Qualification (DQ), Installation Qualification (IQ), Operational Qualification/Performance Verification (OQ/PV) and Performance Qualification (PQ).
Before the first sample is analysed, users have to verify and document that the system meets the user requirement specifications, is correctly installed and working according to the manufacturer’s specifications in the selected environment.
Validation of the system is complete after the instrument hardware, software, data, analytical method and operators are factored in the process. In addition to simple performance tests for each isolated component, it is essential to confirm that the complete system works according to the performance specifications of the analysis method (holistic approach). Here it is important to take the specific requirements of the applied method into account. This ensures that all critical parameters influencing the results are identified and properly monitored over the system’s life cycle.
Best of the Week: Food Analysis, Chemical Migration in Plastic Bottles, STEM Researcher of the Year
December 20th 2024Top articles published this week include the launch of our “From Lab to Table” content series, a Q&A interview about using liquid chromatography–high-resolution mass spectrometry (LC–HRMS) to assess chemical hazards in plastic bottles, and a piece recognizing Brett Paull for being named Tasmanian STEM Researcher of the Year.
Using LC-MS/MS to Measure Testosterone in Dried Blood Spots
December 19th 2024Testosterone measurements are typically performed using serum or plasma, but this presents several logistical challenges, especially for sample collection, storage, and transport. In a recently published article, Yehudah Gruenstein of the University of Miami explored key insights gained from dried blood spot assay validation for testosterone measurement.
Determination of Pharmaceuticals by Capillary HPLC-MS/MS (Dec 2024)
December 19th 2024This application note demonstrates the use of a compact portable capillary liquid chromatograph, the Axcend Focus LC, coupled to an Agilent Ultivo triple quadrupole mass spectrometer for quantitative analysis of pharmaceutical drugs in model aqueous samples.
