UPDATED 09 SEPTEMBER 2017 As described in related articles, the LISST-ABS has a near-constant sensitivity (Volts/concentration) for sediment particles in the >30 micron size range [see Features section here]. In contrast, the sensitivity of optical turbidity degrades with increasing grain size. This...
Laser Diffraction Analysis of NIST 114q Cement per AASHTO Standard T353-14 Laser diffraction analysis of cements is a common industry practice to control quality of cements. Typically, companies must invest in multiple instruments at as many stations. The LISST-Portable|XR is truly portable –...
Holography permits a photograph-like view of particles in water. Photography suffers from a small depth of focus, so that only a small volume of water can be studied with each photo. In contrast, holography has total depth-of-field and therefore, permits viewing particles in a larger volume with each...
This page is written to explain how to interpret your data files. File formats and contents of processed datafiles are described here (note, the page numbers may differ by Manual versions): For LISST-100X User’s Manual, see Appendix A, page 117 [pages before 117 contain other numerical data, e.g....
This is a simple description. For detailed explanations see articles: Laser Diffraction-101 and -201. Particle Size Distribution (PSD) is a multi-parameter description of how the total concentration of particles is distributed into many size fractions. For example, a 32-element PSD means that the...

The LISST-SL2 is an advanced version of the original LISST-SL instrument for sediment transport studies. It is not a sampler. It draws water in and blows it out. No water sample is retained. Laser optics and electronics are contained within the streamlined body. Power and communication is via the 2-conductor...
PRELIMINARY ANNOUNCEMENT – PiA 2018 [photo of venue to come] Date: 24 – 27 September, 2018 Updated: 11 April, 2017. The First PiA Conference will be held in Vittoria, Brazil at the Universidade Federal do Espírito Santo. The initial sponsorship is by the University del Norte, Barranquilla,...
The LISST-VSF is the first autonomous VSF instrument for use in the sea. It measures the Volume Scattering Function, the beam attenuation and scattering coefficients (c and b), and depolarization via the elements P12 and P22 of the scattering Mueller matrix. The LISST-VSF was developed with funding from...
