  • Assay Flux Fire Assay

    Sodium Carbonate (Na 2 CO 3) or soda ash is a powerful basic assay flux and one of the cheapest available for assay purposes:. As it easily forms sulphates and sulphides, it helps desulphurizing the sample (helps preventing the apparition of Matte) .; The other reason for using sodium carbonate, is that it has fluxing effects.

    I. Thallium Flux Assay for KCNQ Channel Openers. The thallium assay was performed using the method of Weaver (1).EC 50 values were calculated by fitting the resulting amplitudes to a single-site logistic equation. EC 50 was defined as the concentration of test compound required to yield 50% of the maximal response. Maximal response, i.e., maximal opening, was the largest signal amplitude

  • The Process of Assaying Black Sands

    Using a standard assay for iron oxide on magnetite/black sand does not work well. The magnetite is too chemically inert to dissolve, to any relevant extent, in the standard assay flux. As a result, it mostly remains undissolved and severely thickens up the assay
