Location: CMS 1345 

The UNCW Sediment Analysis Core Facility houses two instruments, a Camsizer XT Particle Grain Analyzer and a Beckman Coulter LS 13 320 Laser Diffraction Particle Size Analyzer.  These are available for faculty and student use. Samples for both instruments are not preserved after measurement.


The Camsizer is capable of quantifying a variety of grain size characteristics (size, roundedness, dimensional ratios, etc.) for particles ranging from 1μm to 3 mm. Samples can be analyzed dry or in solution. 

The Beckman Coulter is capable of measuring particle size ranging from 10 nm to 2 mm. Samples are analyzed in water.

Sample preparation (organics removal, sample disaggregation, etc.) is the responsibility of the researcher. Facility personnel will do their best to provide advice for sample preparation, but please keep in mind that methods vary widely among sample types and some types of analyses may be new to facility personnel. Researchers are asked to cover the cost of any necessary consumables for sample analysis, but there is no sample fee. 

Faculty or students interested in using the facility should contact Dr. Shannon Klotsko to schedule the initial instrument training. After training approval, please use the booking calendar below to schedule time on either instrument. Default time slots are two (2) hours; book as many as needed.
