SAMPLE PREPARATION AND SEPARATION TECHNIQUES IN BIOANALYTICAL CHEMISTRY

When the development of an HPLC method is complete, the method is usuallytested to ensure its suitability for the intended purpose, often according to guidelinesissued by a regulatory agency (e.g., FDA and ICH). The precision and accuracy ofthe method can be determined by analyzing sui[r]
