Environmental monitoring often requires real-time measurements of parameter in the field under often challenging conditions. Measuring particles in particular requires measurements done very close in time to water sampling: As soon as the water is taken out of its original environment and placed into a sample bottle it is already beginning to change; particles settling to the bottom and possibly clumping together. When these samples are later processed they need to be mixed very hard or even ultrasonicated to bring the samples into solution to measure particle size and concentration. Now the particles are not the same as they were in the original environment. Sequoia’s portable and field deployable instrumentation allow measurements to be made immediately after sampling (LISST-Portable|XR) or automatically on a regular schedule (LISST-ABS).
