validation of chromatographic methods

The site is secure. However, some analytical chemists seem unaware about its importance. Validation is used for testing how well different methods fit for purpose. For the present study, 10.0 μ g/mL of NAR was injected six times to record the system suitability parameters. Validation of a method is the process by which a method is tested by the developer or user for reliability, accuracy and preciseness of its intended purpose.
