Sediment grain size was analysed and compared for standard solids and sediment samples using two different methods; SediGraph and MasterSizer. SediGraph results on sediment samples appeared as finer than those of MasterSizer, and the difference is great especially for biogenic siliceous ooze. The difference is maybe due to the following different points in two methods; pretreatment procedure, sample concentration, detachability on fine grains (about 1 um), and detection principle on nonspherical grains.
