    Dense Heavy Medium Separation HMS / DMS Process

    It has the ability to make sharp separations at any required density, with a high degree of efficiency even in the presence of high percentages of near density material. The density of separation can be closely controlled, within a relative density of 0.005 kg l 1 and can be maintained, under normal conditions, for indefinite periods. The separating density can, however, be changed at will and fairly quickly, to meet

    For a typical density gradient separation, 150 L crude gold nanorod colloid solution was added slowly onto the top of the gradient sucrose solution and centrifuged with an angular speed of 6000 rpm for 20 min (if not mentioned otherwise) by using an Eppendorf 5415D Centrifuge. After centrifugation, gold nanorods in each separated layer was taken out with a pipette and redispersed in deionized water.
