Description
This paper describes the introductive guide for a laser diffraction particle size analyzer(SALD-3000S; Shimazu Co., Ltd.),and discuss the comparison of data obtained from different analytical methods and analyzers.SALD-3000S is abailable for any sand and mud material,and its measurement range covers from 0.08 to 3000μm.SALD-3000S has several advantages such as simple suitability of a laser axis,and real-time modulation of sample bulk concentration,in comparison with previous laser diffraction particle size analyzers.Measurements of well-known diameter samples coincide with true values of diameter.Measurements of sand-mud samples with three different grain analyzers of a settling-tube grain sizer,the previous laser diffraction particle size analyzer(measurement range:0.1-192μm),and SALD-3000S,suggests that SALD-3000S provides the most precise and is the simplest to measure.
