Reagent Chemicals [a] is a publication of the American Chemical Society ACS Committee on Analytical Reagents  , detailing standards of purity for over four hundred of the most widely used chemicals in laboratory analyses and chemical research. The American Chemical Society does not validate the purity of chemicals sold with this designation, but it relies on suppliers, acting in their self-interest, to meet these standards. This arrangement has worked well for many decades. In addition to specifications for each chemical, Reagent Chemicals provides detailed methods for determining how to measure the properties and impurities listed in the specifications. There are detailed explanations of many types of analyses — gas, liquid, ion, and headspace chromatography, atomic absorption spectroscopy, and optical emission spectroscopy, to name a few. Reagent Chemicals is primarily of interest to manufacturers and suppliers of chemicals to laboratories worldwide.
If this condition is not met, this electrode may not be used for the measurement and must be exchanged for another one which does meet the condition. Most manufacturers recognize a variety of these specialty grades; however, certain brands and manufacturers have developed their own material grades specialized for certain laboratory applications or equipment. Chemists could improve sensitivity levels, as well as testing accuracy. Setting m l.
