In chemistry, a chemical test is qualitative or semi-quantitative procedure designed to prove the existence of a chemical compound or chemical group with the aid of a specific reagent. Subcategories This category has the following 3 subcategories, out of 3 total.
Analytical chemistry studies and uses instruments and methods to separate, identify, and quantify matter. [1] In practice, separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes.
All analytical procedures should be validated. Identification tests are conducted to ensure the identity of an analyte in a sample through comparison of the sample to a reference standard through methods such as spectrum, chromatographic behavior, and chemical reactivity. [5] Impurity testing can either be a quantitative test or a limit test.

The Zeisel determination or Zeisel test is a chemical test for the presence of esters or ethers in a chemical substance. [1] [2] [3] [4]It is named after the Czech chemist Simon Zeisel (1854–1933).
A test method is a method for a test in science or engineering, such as a physical test, chemical test, or statistical test. It is a definitive procedure that produces a test result. [ 1 ] In order to ensure accurate and relevant test results, a test method should be "explicit, unambiguous, and experimentally feasible.", [ 2 ] as well as ...
An assay (analysis) is never an isolated process, as it must be accompanied with pre- and post-analytic procedures. Both the communication order (the request to perform an assay plus related information) and the handling of the specimen itself (the collecting, documenting, transporting, and processing done before beginning the assay) are pre-analytic steps.
