Elutriation is a process for separating particles based on their size, shape and density, using a stream of gas or liquid flowing in a direction usually opposite to the direction of sedimentation. This method is mainly used for particles smaller than 1 μm.

Elutriation is a well-established technique developed in 1948 [22], which separates particles based upon size and sedimentation density, utilizing both centrifugal force and counter flow drag force. The elutriation chamber is a specialized piece of equipment that allow the flow of buffer through the chamber during centrifugation.

淘析是指用洗涤和倾析的方法从混合物中除去某些物质，也指是利用上升流体（往往是水流或气流）进行颗粒分级的方法。 该过程是逆重力沉降过程， 斯托克斯定律 也适用于此。 [1] 淘析是指利用粉体细颗粒与空气或水同时流动而排出的方法，即进行粉体分级的操作叫淘析，利用这个原理可把粉体试料分级或进行粒度测定。 [2] 淘析分析法，也叫做淘汰分析法。 这是指利用上升流或水平流使粉状物料分成不同粒径的分级方法。 淘析器是指利用风力或水力的分级作用，进行粉体 …

Elutriation is a centrifugation technique that aims to separate particles based on size and density. This is achieved through an elutriation rotor. An elutriation rotor is designed to separate and/or concentrate monodisperse suspensions of single cells or particles according to size (approximately 2 to 50 µm in diameter).

Elutriation is described by Wang (1) as “A process of sludge conditioning whereby a sludge is washed either by fresh water or plant effluent, to reduce the sludge alkalinity and fine particles, thus decreasing the amount of required coagulant in further treatment steps, or in sludge dewatering,” as shown in Fig. 1. Elutriation is the term ...

Jan 1, 1989 · The definition of elutriation is separation or removal by washing. Centrifugal elutriation of cells is accomplished in a rotor that allows a counterflow of medium through a separation chamber opposing the centrifugal force; the balance of the opposing counterflow of medium and centrifugal force underlies the separation.

May 1, 2009 · Here we reveal a method for suppressing the effects of particle size so that particles can be routinely elutriated on the basis of their density. The particles are suspended by fluidizing with water, and then conveyed into channels inclined at 70° to the horizontal, closely spaced with a gap of 1.77 mm.

淘洗 是一种根据粒径和密度分离颗粒的离心技术，所用转头为淘洗转头。 淘洗转头根据粒径（直径约 2-50µm）分离和/或浓缩单一分散度的细胞或颗粒悬浮液。 淘洗转头结合两种分离技术，同时有两种反向力作用于转头腔室中的每个细胞上： 离心力：推离细胞远离旋转轴心。 这是一种在离心力作用下的沉降过程。 流体力：将其推向旋转轴心 ——“反向流动淘洗”。 这是一种通过洗脱方式进行的分离过程。 分离发生在漏斗状淘洗腔室内。 当转头在离心机中旋转时，细胞悬浮液 …

Elutriation is a gentle process known as counter-current centrifugal elutriation. In this process, the PBMCs are placed into a specially designed centrifuge rotor/chamber and subjected to centrifugal field.
