Validation of analytical procedures is imperative in demonstrating that a drug substance is suitable for a particular purpose. [5] Common validation characteristics include: accuracy, precision (repeatability and intermediate precision), specificity, detection limit, quantitation limit, linearity, range, and robustness.
Method precision (Repeatability): Method precision carried out on different test preparation of a homogenous sample within short interval of time under same experimental conditions. 4.9. Intermediate precision (Ruggedness): Intermediate precision (Ruggedness) expresses within-laboratories variations i.e. different days, different analysts ...
These machines feature high-quality imaging and can be used to examine samples. It saves money and energy over transporting heavy, bulky samples to labs for chemical analysis. Portable spectrometry equipment is used in drug testing, drug discovery, food quality control, environmental testing, carbon dating, and the defense industry.
Drug checking or pill testing is a way to reduce the harm from drug consumption by allowing users to find out the content and purity of substances that they intend to consume. This enables users to make safer choices: to avoid more dangerous substances, to use smaller quantities, and to avoid dangerous combinations.
