AR Grade Chemicals

AR grade chemicals, also known as Analytical Reagent grade chemicals, are a type of chemical that is characterized by its high purity. They are specifically formulated for use in laboratories where accuracy and precision are essential.

AR grade chemicals meet strict specifications that are set by organizations like the American Chemical Society (ACS). These specifications outline the minimum purity of the chemical, as well as the maximum levels of impurities that are allowed.

AR grade chemicals are used in a wide variety of analytical techniques, including:

• Quantitative analysis: This type of analysis is used to determine the amount of a particular substance in a sample. AR grade chemicals are essential for quantitative analysis because they ensure that the results are accurate and reliable.
• Qualitative analysis: This type of analysis is used to identify the components of a sample. AR grade chemicals can be used for qualitative analysis as well, although they are not as essential as they are for quantitative analysis.
• Synthesis: AR grade chemicals can also be used for the synthesis of new compounds. However, it is important to note that not all AR grade chemicals are suitable for synthesis. Some AR grade chemicals may contain impurities that could interfere with the reaction.

AR grade chemicals are typically more expensive than other grades of chemicals, such as technical grade or reagent grade chemicals. This is because they require more extensive purification to meet the strict specifications. However, the cost of AR grade chemicals is often justified by the increased accuracy and reliability that they provide.
