Scope and Methodology
The scope of EN 19380 validation covers the entire lifecycle of an analytical method used for multivitamin analysis. This includes the initial development, optimization, validation, and ongoing monitoring to ensure that the method remains accurate and reliable over time.
The methodology outlined in this standard is designed to be comprehensive yet flexible, allowing laboratories to adapt it to their specific needs while ensuring adherence to international best practices. The primary objective is to provide a robust framework for validating methods used in multivitamin analysis, covering all critical aspects from sample preparation to result interpretation.
Sample preparation is the first step in any analytical process and involves several key procedures:
- Solubilization: Ensuring that the vitamins are fully dissolved in a suitable solvent for analysis.
- Purification: Removing impurities that could interfere with the detection of vitamins.
- Dilution: Adjusting the sample concentration to match the range of the analytical method.
The next stage is the actual analytical measurement. Depending on the type of vitamin and its form, different techniques may be employed such as high-performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC-MS), or atomic absorption spectroscopy (AAS). Each technique has its strengths and limitations, and selecting the appropriate one is crucial for accurate results.
After obtaining the raw data from the analytical instruments, it needs to be processed and analyzed. This involves several steps:
- Data Quality Check: Ensuring that the data obtained are free from errors or anomalies.
- Data Interpretation: Converting numerical values into meaningful information about the vitamin content in the sample.
- Result Reporting: Presenting the results in a clear and concise manner, often including tables and graphs for easy interpretation by stakeholders.
The validation process involves several key steps as outlined in EN 19380. These include method selection, calibration, linearity assessment, precision determination, accuracy evaluation, and robustness testing. Each step is designed to ensure that the analytical method meets all necessary criteria for reliability and accuracy.
Method selection is critical as it determines which technique will be used for analyzing the vitamins in question. Calibration ensures that the instruments are operating within acceptable limits, while linearity assessment checks whether there is a consistent relationship between the measured values and the true concentrations of the analytes. Precision determination assesses how consistently the method produces similar results over repeated measurements, whereas accuracy evaluation compares the actual results with known reference standards.
Robustness testing evaluates how well the method performs under varying conditions, such as changes in temperature or pH levels. By conducting these tests rigorously and adhering strictly to EN 19380 guidelines, we ensure that our clients receive reliable and accurate data every time they perform an analysis.
