Measurement of the particle size of soil and sediment sample is a critical part of understanding the geological history of a particular area. The nature of most samples is a wide range of particle sizes, from sub-micron clay up to sand and gravel. The relative contributions across these size ranges have traditionally been measured with several different analytical techniques to cover the range, including sedimentation and sieves. The wide measurement range of the LA-960 allows samples to be run very quickly and to cover the size range in one analysis.
