http://www.safereagents.com/The Karl Fischer Reagents consist of a solvent Alcohol (ROH), a known concentration of Iodine (I2), a Base (RN) and Sulfur dioxide (SO2). Principle of Reaction. The Bunsen reaction between iodine and sulfur dioxide in an aqueous system is the basis for the Karl Fischer Reagents reactions. HPLC Reagents is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. Industrial gases are the gaseous materials that are manufactured for use in industry. The principal gases provided are nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium and acetylene, although many other gases and mixtures are also available in gas cylinders. The industry producing these gases is also known as industrial gas, which is seen as also encompassing the supply of equipment and technology to produce and use the gases. Their production is a part of the wider chemical Industry (where industrial gases are often seen as "specialty chemicals"). Dust Filter Bag are widely used for the filtration of high temperature waste gas from various industrial furnaces. Filter paper is a semi-permeable paper barrier placed perpendicular to a liquid or air flow. It is used to separate fine solid particles from liquids or gases. In addition to the above products, our company also other products for customers to choose from.
