SOP is short for Standard Operation Program. It is now available in smart laser particle sizing
instruments, facilitates operation automation and standardization, and is used to achieve 'one-click' operation.
SOP reduces the labor intensity, and, more importantly, standardizes the test conditions, minimizes the errors caused by different operators, and improves the reproducibility of the test results. Before applying SOP, the standard operation procedures should be set up, including the cycle cleaning times, dispersing time by ultrasonication, shading range of the sample, circulating speed, data storage, result printing, and automatic alignment, etc.
