Limit tests - A brief study on its role and significance in pharmaceuticals

This article illustrates about the limit tests that are usually done in the pharmaceutical field (pharmaceutical chemistry lab). The limit tests provide us a wide range of information about the presence of impurities in the pharmaceutical sample. These are quantitative or semi quantitative tests that are designed to detect or limit small quantities of impurities that are likely to be present in the substance. These are based on the comparisons of the test and the standard with reference to Indian Pharmacopoeia (IP), British Pharmacopoeia (BP), Japanese Pharmacopoeia (JP) and United States Pharmacopoeia (USP). It can be detected visually or mechanically.
