First step, which comprises of purchasing, storage, and analysis of materials, mandates detailed lab experiments of the purchased materials, including various property tests and trials run by various spectroscopes such as the UV, HPLC, GC, and CCM. In the second step, in which the procedure of each synthetic process of dyestuffs is analyzed, the purchased materials are run through step-by-step TLC and HPLC analyses according to a standardized set of criteria and processes. Third step, in which final products are standardized through dyeing, ensures standardization of all aspects of the final products through dyeing, including color, durability, physical properties, package, and storage. |
