Suppliers of 1250 mesh materials must adhere to strict quality control measures to guarantee the integrity of their products. They often utilize advanced technologies, such as high-energy ball mills, air classifiers, and ultrasonic sieving equipment, to achieve the desired particle size distribution. These processes not only ensure the fineness required but also maintain the original properties of the material, be it a chemical compound, a mineral, or an organic substance.

Macromolecular oxidation was detected in proteins by the colorimetric measurement of Advanced Oxidation Protein Products (AOPP) and in lipids by the colorimetric quantification of malondialdehyde (MDA). Standard curves were run with chloramine-T and 1,1,3,3 tetraethoxypropane (TEP) for AOPP and MDA methods, respectively [29][30][31]. Values were normalized to initial protein content in samples, measured with Bradford reagent [32]. The standard deviation of at least six measures was calculated and p-value < 0.05 were considered significant.

Gravimetric analysis is a method of quantitative chemical analysis in which a substance is converted into a stable compound of known composition, and the mass of this compound is then measured. This technique offers a high level of precision and is particularly useful in determining the concentration of materials within complex mixtures. The gravimetric determination of titanium dioxide typically involves a series of well-defined steps, which include precipitation, filtration, washing, drying, and weighing.
