Webb2 nov. 2024 · 1. The Crush Test. This is quite a violent method of telling salt and protein crystals apart, so it’s great if you’ve got some pent-up frustration to vent. Protein crystals contain, on average, about 40% solvent (they’re very gap-ey), [2] whereas it’s relatively common for salt crystals to contain no solvent at all.
