We are looking for the best substrate for microplastics measurement with Raman. Sometimes the filters with samples from freshwater, have a lot of other particles as MPS that difficult the examination under the Raman, so we plan to manipulate the microplastics to another substrate to analyze latter under Raman.

María Belén Alfonso Try filter mesh (25-30 microns). For issue of organic matter try adding weak acid to the sample, it will dissolve the particles and keep the microplastics only.

Next use very high quality optical microscope to identify the MPs from the mesh and remove it with the help of very sharp foreceps onto a slide or petri plate to see under Raman or FTIR.

How to calculate Total Flavonoid?

I analyzed flavonoid total spectrophotometry, the procedure as below: 2 ml supernatan added 5 ml dd.H2O, then added 0,15 ml NaNO2 5%, 5 minutes later added 0,15 ml AlCl3 10%, After 6 minutes,...

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...
