Biochemical assays

摘要

Components of gaseous mixtures, which are present in the gas as a fluid, e.g. a gas, vapor or mist are assayed biochemically by conducting an enzymatic reaction wherein the fluid substrate is added to a liquid medium containing the enzyme. Particular reactions include the measurement of monoethylene glycol in natural gas employing a glycol dehydrogenase/NAD+ system and determing the amount of NAD+ reduced.
