    摘要: Lipid is determined quantitatively by treating a sample with a surfactant in an aqueous medium to obtain a liquid sample dispersion, then reacting the dispersion with a reagent containing cupric ion and bicinchoninic acid, and measuring a colored state developed by complex formation of bicinchoninic acid with cuprous ion formed from cupric ion in the presence of lipid. This method can be effectively applied to determination of amphiphilic lipid having a tendency of gathering in an aqueous medium. Further, two different species interfering with each other in quantitative determination thereof are determined respectively by conducting two different determination methods on the same sample followed by calculation using the values obtained.

    摘要: An ink jet recording process employing an ink which comprises a liquid medium containing at least water and an organic solvent and containing therein a water-soluble dye selected from the group consisting of a solubilized vat dye, a solubilized sulfur dye, a leuco salt of a vat dye, and a leuco salt of a sulfur dye. In one embodiment of the invention, the ink can be fixed on a recording medium by oxidation, and is suitable for ink-jet printing.
