How LISST Works! [Sequoia, April 14, 2011] Laser Diffraction 101 Sequoia realizes that for some people, the principle behind laser diffraction seems difficult to understand. The purpose of this article and ‘Laser Diffraction 201’...
get_bf.m [Sequoia, April 5, 2011] This MATLAB script allows the LISST-100 or LISST-100X user to compute the part of the forward scattering coefficient, bf, covered by the angle ranges of the LISST-100X. See the application note ‘Angles...
[Sequoia, April 5, 2011] ppm vs concentration in mg/l or µl/l? How is ppm related to concentration? ppm means parts-per-million. But what parts? The amount of particles in a suspension can be expressed as the total volume OR total mass of particles in...
Size Bins for use with Matrices based on Randomly Shaped Grains [Sequoia, March 18, 2011] The tables below tabulate the values for the Type B and C size bins for inversions based on Sequoia’s matrices for randomly shaped particles....
The Influence of Particles Outside the Size Range of the LISST [Sequoia, February 23, 2011] A question that Sequoia often gets asked is: What happens when the suspension contains particles outside the measurement range? The short answer...
