Main Questions 1) How does particulate matter affect refractive index (RI) measurements? 2) Do VST filters affect sample content (nondissolved solids or otherwise)? Abstract Nondissolvable, light-scattering solids (i.e., titanium dioxide, TiO2) were added, in increasing amounts, to various solutions. The … Continued
Updated: 26 May 15 Abstract Continuing from our previous post on refractometer comparisons, the goal of this study was to examine the measurements from three refractometers advertised to measure the total dissolved solids (TDS) content of coffee. In three separate … Continued
Abstract The goal of these two studies was to examine the measurements from two refractometers advertised to measure the total dissolved solids (TDS) content of coffee. Utilizing mixed study designs, the VST LAB Coffee II Coffee & Espresso Refractometer (the … Continued
