How do calibration columns work
WebThe calibration column must be mounted in a vertical position and must be below the level of the liquid in the tank so that it will fill when a valve is opened. Two ball valves of the … WebCalibration Columns. Neptune Calibration Columns provide a fast, easy and economical means of checking the flow rate of your chemical metering pump. The most accurate test of metering pump flow rate is to measure the drawdown rate on the suction side while leaving the discharge undisturbed in its normal, steady state operating condition.

WebMolecules with sizes larger than the exclusion limit do not enter the tunnels and pass through the column relatively quickly by making their way between the beads. Smaller molecules, which can enter the tunnels, do so, and thus, have a longer path that they take in passing through the column. WebBroad Standard Calibration. One can also calibrate the GPC column set using a broad standard that is the same polymer being run as the unknown. Broad standard can be purchased from a variety of different vendors, and the standard should be well characterized, i.e. the number, weight, Z and possibly viscosity average molecular weights have been …
