Sequoia’s Laser In Situ Scattering and Transmissometry (LISST) particle size analyzers have significantly advanced the understanding of flocculation in aquatic environments. Since the mid-1990s, LISSTs have often replaced or supplemented older technologies...
In 2019 Sequoia published a short note on our website regarding the feasibility of measuring plastic particles in situ. Two main conclusions were drawn: If one considers the number concentration of plastic particles (α), and the sampling volume (SV)...
In 2008, Sequoia Scientific’s Dr. Ole Mikkelsen co-authored and published a paper: The Influence of Schlieren on In-situ Optical Measurements Used for Particle Characterization. This paper was based on data collected during his postdoctoral work...
24th July 2020 In the last several years, Sequoia has introduced a range of new or upgraded instruments: LISST-200X, LISST-SL2, LISST-Holo2, LISST-ABS, LISST-AOBS, LISST-HAB, LISST-Black, LISST-Glider, Hyper-bb and LISST Horizon. Such an expansion increases...
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....
