There are various Autoclave Qualification Tests that need to be done along with procedure and acceptance criteria. Autoclave works by using heat and pressure to kill the microorganisms such as bacteria and spores so it becomes very crucial or very important equipment for sterilization processes In this article we will go through the few prerequisites … Read more
Lead is a most undesirable impurity in pharma compounds and comes through the use of sulphuric acid, lead-lined apparatus, and glass bottles used for the storage of chemical materials so, we do a Limit Test for Lead to identify the acceptance level of lead in a sample. Limit test for lead Principle The limit test … Read more
The limit test for arsenic is based on the reduction of the arsenic in the arsenic state to the arsenic gas with zinc and hydrochloric acid. The arsenic gas stains the mercuric chloride paper yellow. The paper is dissolved in acid where the arsenic present as an impurity in the sample gets converted into arsenic … Read more
The Limit Test for Sulphate is designed to determine the allowable limit of Sulphate contained in a sample. Principle: The principle for the limit test of Sulphate is based on the reaction of soluble Sulphate with barium chloride in the presence of dilute hydrochloric acid to form barium Sulphate which appears as turbidity with a … Read more
A limit test for chloride is done to identify the impurity in the compounds by comparing the test solution against the standard solution. The chloride limits test is only designed to identify and control the impurity present in the compounds. Limit Test for Chloride Principle The limit test for chloride is based on the reaction … Read more
The limit test for iron refers to a type of analytical chemistry test used to determine the concentration of iron in a sample. This test is often performed in the laboratory as part of a larger suite of tests to determine the chemical composition of a substance.In a limit test for iron, a known volume … Read more
In pharmaceutical analysis, a limit test is a type of analytical test used to determine impurity in a substance whether a substance is present in a sample at a concentration above or below a specified limit. Limit tests are often used to ensure that a substance meets certain quality standards or regulatory requirements. Definition The … Read more

High-Performance Liquid Chromatography (HPLC) is used in pharmaceuticals for the analysis of drug mixture and their components. HPLC is reverse-phase Liquid Chromatography. This technique is used for thermal labile, high molecular weight peptides, and non-volatile compounds. The main purpose of HPLC is used to examine the mixture for its identification, impurities, and purification. The mixture … Read more
Injectable preparations, also known as parenteral preparations, are sterile formulations used for parenteral infusion or implantation. They are administered by injection to maintain sterility and prevent contamination by foreign matter, pyrogens, microorganisms, and bacterial endotoxins. These preparations must be made using methods that ensure sterility. Water for injection (WFI) is commonly used as a vehicle … Read more
