Significance of Internal standard
The term "internal standard" refers to a known quantity of a substance added to a sample to enhance the accuracy and precision of analytical measurements. This concept applies to various analytical methods, where substances like eperisone hydrochloride, verapamil, and prednisone are employed. By compensating for variability in sample preparation and analysis, internal standards improve the reliability of quantification for target substances, ensuring consistent and precise results across different analytical scenarios.
