Analysis Reagents and Reagents of the Electronics Industry
The purpose of a reagent is to catalyze a chemical reaction or to determine if a reaction will occur. The reaction may prove the presence or absence of a substance or chemical, or analyze a known chemical. Two separate fields – analysis reagents and electronic industry reagents – are among many specialty industries requiring the use of reagents. Industrial chemical supplier Bell Chem is proud to offer reagents for these industries and others.
Analysis (or analytic) reagents are utilized in analytical chemistry, using a change of color, precipitation, fluorescence or an alternate method of recognition to determine if another chemical or additive is present and, if so, at what concentration.
Reagents generally have 2 strong factors – sensitivity and selectivity – that set them apart from other chemicals and categorize them into a number of varied roles. Reagents may be specific, in which case their reaction occurs with only a scant number of chemicals to ascertain their presence within a substance. An example of a selective analytical reagent is silver nitrate, which reacts by precipitation when chloride or bromide are present. On the other side of the coin are group reagents, which are able to separate several ionic substances simultaneously. The majority of inorganic analytical reagents fall into the category of specific agents while organic analytical reagents are generally group reagents.
Bell Chem stocks a number of analysis reagents including glacial acetic acid, boric acid, hydrochloric acid, nitric acid, phosphoric acid, potassium hydroxide, and sulfuric acid, which will prove or disprove the presence of an analyte – a substance identified by its chemical components. These chemicals may be used in conjunction with varied forms of instrumental analysis, such as lasers, chromatography, capillary electrophoresis, titration, water quality control, mass spectrometry, or simple microscopy.
An important sub-field of analysis reagents is within the electronics industry. Electronics demand extremely precise reagents of ultra high purity (99.99% pure is often referred to as 4N while 99.999% pure is 5N) to detect slight infiltration of unwanted metallic debris (trace element analysis), often detecting metallic infiltrates ranging from parts per billion (ppb) to parts per trillion (ppt). These reagents are often categorized as ASTM level “O”. Electronic grade reagents are referred to as “wet” chemicals since they are primarily utilized in a liquid form. Among electronic grade reagents stocked by Bell Chem are acetic acid, acetone, hydrochloric acid, hydrogen peroxide, isopropyl alcohol, nitric acid, phosphoric acid, and sulfuric acid.
Electronic-grade reagents are utilized in scientific research fields, in fiber-optic communications, in microelectronics and semiconductors, and chemical and physical trace analysis.
