IMTAKT GLOBAL NETWORK IMTAKT HPLC TOOLS 2 Sample Concentration Calculator Accurate weighing of analytes is an essential task when preparing your sample solution for injection. This tool will make the tedious process of calculating sample weight and solution volume much easier to achieve a desired sample concentration. This tool will also make it simple to find the molar concentration of your sample by inputting the molar mass (molecular weight).       1 Column Pressure Unit Converter HPLC instruments use a wide variety of pressure units, even though SI has defined the standard unit of measuring pressure to be “MPa”. Some common units used are MPa, bar, psi and kgf/cm2. This tool makes it convenient to convert a pressure value from one unit to another.         Copyright: I.YAZAWA (Imtakt Corp., JAPAN)
