A 200-mesh claim and the word micronized are both shorthand. What each one can and cannot tell you, when sieve analysis is enough, and how to write a particle-size limit that a lot has to meet.
Mesh is a sieve shorthand, not a specification. How to make 80 and 200 mesh comparable, test dispersion at the intended dose, and write a particle-size limit into the RFQ.
A salt assay near 99% and an L-carnitine result near 68% can describe the same pure material. How to name the analyte, the basis and the method so a COA actually releases a lot.
A 98% HPLC result is only the headline. How to tie the L-theanine COA to a lot, read the assay basis, and keep L-form evidence separate from a routine non-chiral assay.
