Mass Flow Controllers Enable Accurate Calibration
How Mass Flow Controllers Enable Accurate Calibration Standards. Calibration is a critical, yet often overlooked aspect of benchtop chromatography. Guidance on the frequency that gas chromatographic workflows should be calibrated is generally aligned, with the consensus being once every three months is sufficient. However, some believe that calibration can remain stable for up to six months, while other users calibrate as a matter of course before any experiment. The guidance deviates even more...

Comparison of Thermal Mass Flow Technology
Mass Flow vs. Volumetric Flow - To avoid confusion when discussing flow or flow rate, it is important that the correct terms are used and that the concepts of flow rate, volume flow rate and mass flow rate are clearly understood. In general Flow Rate can be understood as the actual velocity (V) of the moving fluid, whereas Volumetric Flow Rate (Q) is expressed in units such as cubic feet, actual cubic feet, cubic meters, liters, cubic centimeters, etc., flowing through a cross sectional area...
