53breath test — any of various tests in which a person s breath is analyzed for presence of something abnormal. Subgroups called the 13C breath tests and 14C breath tests involve administration of organic compounds labeled with carbon 13 (heavy carbon) or carbon …
54depositional carbon — n as used in Test Method D5061, a group of carbon forms that are formed from cracking and nucleation of gas phase hydrocarbon molecules during coal carbonization. D5061 • pyrolytic carbon sooty carbon spherulitic carbon …
55aminopyrine breath test — (for liver function) a breath test in which the patient is given a dose of 14C labeled aminopyrine and at 15 minute intervals for two hours the amount of 14C labeled carbon dioxide in the patient s breath is measured. Excessively low levels of… …
56caffeine breath test — (for liver function) a breath test in which the patient is given a dose of caffeine labeled with carbon 13; excessively low levels of labeled carbon dioxide in the patient s breath indicate inadequate metabolism of it by the liver, as in patients …
57Aniline acetate test — The aniline acetate test is a chemical test to identify the presence of certain carbohydrates. When any of these carbohydrates reacts with aniline acetate, furfural is produced, causing a bright pink color.Hydrochloric acid interacts with… …
58Bromine test — The bromine test is a qualitative test for the presence of unsaturated C–C bonds and phenols.In this laboratory method, an unknown sample is treated with a small amount of elemental bromine mdash; either as an aqueous solution, or as a solution… …
59pyrolytic carbon — n as used in Test Method D5061, an anisotropic carbon form that is formed by the deposition of carbon parallel to an inert substrate causing the resulting texture to appear ribbon like. D5061 …
60spherulitic carbon — n as used in Test Method D5061, a spherical anisotropic carbon form sometimes referred to as thermal black that is formed by the deposition of carbon concentrically around a nucleus. D5061 …
