What Is ACS Grade? How Does It Differ from AR Grade?
A clear guide to chemical grade terminology for laboratory and analytical use
Direct AnswerACS grade refers to a chemical purity standard set by the American Chemical Society (ACS), which defines minimum specifications for certain chemical reagents used in analytical and laboratory work.
What Is AR Grade and What Is It Used for in the Laboratory?
AR Grade (Analytical Reagent Grade) is a high-purity chemical grade manufactured for laboratory analytical work where accuracy, consistency, and low impurity levels are important.
Acetonitrile vs Methanol: Which Solvent Should You Choose for HPLC?
A practical comparison guide for HPLC method development and solvent selection
Direct AnswerAcetonitrile and Methanol are both widely used solvents in HPLC mobile phases, but they behave differently.
What Is Acetonitrile and What Is It Used for in the Laboratory? Direct Answer
Acetonitrile is a clear, highly polar organic solvent that laboratories commonly use for chemical analysis, sample preparation, extraction, and chromatography. In analytical laboratories, many users know Acetonitrile as a mobile phase solvent for High Performance Liquid Chromatography, or HPLC.
Because Acetonitrile mixes well with water, has relatively low viscosity, and works well in many chromatographic methods, laboratories use it in research, quality control, pharmaceutical analysis, food testing, environmental testing, and other laboratory applications.
How to Choose Acetonitrile for HPLC Solvents
To choose Acetonitrile for HPLC, select a solvent grade that is specifically designed for chromatographic analysis. Key factors include high purity, low UV absorbance, low residue, consistent lot-to-lot quality, suitable water content, and reliable documentation such as specification, SDS, or COA. For routine HPLC analysis, HPLC grade Acetonitrile is commonly used, while more sensitive techniques such as LC-MS may require LC-MS grade solvent.
HPLC vs LC-MS Grade Solvents
(A Practical Guide to Choosing the Right Solvent Grade for Analytical Applications)
Direct AnswerHPLC grade solvents and LC-MS grade solvents are both high-purity solvents for analytical laboratories.
What is HPLC Grade Solvent?
(A Practical Guide to High-Purity Solvents for Chromatographic Analysis)
Direct AnswerHPLC grade solvent is a high-purity solvent made for High Performance Liquid Chromatography, or HPLC. Manufacturers control this type of solvent for low impurities, low residue, consistent lot-to-lot quality, and suitable optical properties such as low UV absorbance at relevant wavelengths.
