Working Limits of Particle Concentrations

This article is corrected and simplified,17 Sept. 2018 What is the measurable concentration range of LISST instruments? In Brief:  The range of concentrations that LISST instruments can measure depends on particle size. For laser-diffraction LISST instruments, the recommended upper limit of concentrations...

Rich Details of a River Column Revealed by LISST-SL

These data show use of LISST-SL and -SL2 from bridges. For use from boats, click here. UPDATED 18 SEPT 2017 The LISST-SL2 instrument delivers the most powerful suite of sediment data. It is an isokinetic instrument (isokinetic means intake velocity matches river velocity). The parameters it measures...

LISST-ABS River Profiles by USGS

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...

In-Line Holography Introduction

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...

Interpreting Particle Data

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....
