High Performance Liquid Chromatography (HPLC) is a well-established technology for separating, identifying, and quantifying components of a mixture in analytical practices. For the production of reagents, buffers, mobile phases, and any sample preparation, HPLC analysis needs Type I ultrapure water. The American Society for Testing and Materials (ASTM) has designated ultra-pure water as Type I on the basis of purity (<50 ppb of Total Organic Carbons), low conductivity (<0.056 μS/cm), and UV-absorbance. Type I water is required when HPLC is used in combination with a mass spectrometer (MS) for the ultra-sensitive applications. Lab Alley is selling its ultra-pure HPLC Grade water in the United States of America. Lab Alley's HPLC grade water is widely used in regular HPLC operations and Ultra High- Performance Liquid Chromatography (UHPLC) applications.HPLC grade is highest grade of chemicals used for HPLC analysis. Pure HPLC Grade Water is a better quality than Lab Grade Water, USP Grade Water And Reagent Grade Water.  HPLC Grade Water is used in most HPLC mobile phases and in sample preparation. Because it dissolves most substances and is nontoxic, it is known as a Universal Solvent. HPLC grade water is water wherein a specific conductivity (16-18) is maintained by ELGA water machine and filtered through 0.22 micron filter to avoid the particulate matter.Â
