![]() The purity of the blood cell fractions ranged from 92 to 98%, and the viability fell in the range 97-99%. The throughput of diluted blood is 162 mL/h and that of whole blood is about 2 mL/h or approximately 10(10) cells/h guidelines are given for significantly increasing throughput. In the first step, a stream of diluted blood is separated into one fraction consisting of platelets and plasma and another containing blood cells. These five steps are carried out in sequence using a single apparatus, with conditions varying from step to step in accordance with theoretical guidelines in order to achieve the desired cut points. Production of the six fractions requires five steps, each yielding two fractions. Split Flow Thin Cell Fractionation (SPLITT) is good for sample pre-treatment and clean-up as well as for production purposes.Centrifugal SPLITT fractionation, a technique designed for the continuous high-resolution separation of colloids and low-density particles, is applied here to fresh human blood, producing six purified fractions consisting of proteins and lipoproteins, platelets, red blood cells, lymphocytes, monocytes, and neutrophils. The system has two outlets (one for the smaller and one for the bigger sized particles) where the separated size fractions can be constantly collected. That means a feed flow of non-separated sample can be continuously pumped into the Split Flow Thin Cell Fractionation (SPLITT). The FFF techniques separate particles in the direction of flow, separating them according to their differing elution velocities, while the SPLITT techniques. In contrast to the other FFF techniques, Split Flow Thin Cell Fractionation (SPLITT) can separate particles in the size range of 1-100 µm on a continuous basis. SPLITT is performed by pumping the sample containing liquid into the top inlet at the start of the channel, whilst simultaneously pumping a carrier. Hanno Kinkel, University of Kiel, Germany). Split flow thin-cell fractionation Split flow thin-cell fractionation (SPLITT) is a special preparative FFF technique, using gravity for separation of m-sized particles on a continuous basis. The SEM picture shows Coccolithes, which can be fractionated by using Split Flow Thin Cell Fractionation (SPLITT) (courtesy provided by Dr. Split Flow Thin Cell Fractionation (SPLITT) has applications in the biomedical field (cell separations), in the environmental area (diatoms, sediments, algae, soil particles) and in the chemical sector (polymer and silica particles). Split Flow Thin Cell (Splitt) Applications Because earth gravity is used as separation force, Split Flow Thin Cell Fractionation (SPLITT) is limited to particles down to ca. By controlling the flow rate ratios of the two inlet streams and the flow rates of the two outlet streams, the separation can be controlled and the sample can be separated in two distinct size fractions. There are different ways of performing SPLITT in the most common way, the sample containing liquid is pumped into the top inlet a’ at the beginning of the channel and a carrier liquid is at the same time pumped into the bottom inlet b’. Centrifugal SPLITT fractionation combined laminar flow hydrodynamics and centrifugal sedimentation to obtain a con- tinuous binary separation of suspended. Split Flow Thin Cell Fractionation (SPLITT) was invented and first published by Prof. Split Flow Thin Cell Fractionation (SPLITT) is a special preparative Field-Flow Fractionation technique, using earth gravity for separation of µm-sized particles on a continuous basis.
