Sequoia’s LISST-200X enjoys popularity amongst microplastics researchers. The instrument has been used to analyze microplastic particle distributions from disposable masks[i] , investigate interactions between oil droplets and microplastics[ii],[iii],[iv]...
The articles discuss the use of Sequoia’s LISST-VSF instrument, a submersible multi-angle polarized light scattering meter measuring the volume scattering function (VSF) in situ. Commercially available since 2012, the LISST-VSF’s capabilities have...
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)...
Bubbles in water are studied intensively. For modeling and measurement purposes it is sometimes assumed that bubbles are spherical, but this is only true up to a certain size: When the hydrostatic pressure difference from top to bottom of the bubble is...
