8 results about "Separation procedure" patented technology

A blood separation device includes a pump system, a separator, and a controller. The controller is programmed to execute a blood separation procedure including a red blood cell collection stage in which blood is conveyed into the separator, red blood cells are separated from the blood in the separator, and the separated red blood cells are conveyed from the separator into a collection container. The red blood cell collection stage is ended when a target volume of blood has been separated in the separator. The controller then determines a percentage of the red blood cells from the target volume of blood that have been collected in the collection container based on the volume of red blood cells and the hematocrit of the fluid in the collection container, a volumetric flow rate of pure red blood cells in the blood conveyed into the separator, and the procedure time.

The invention relates to the technical field of sugar alcohol preparation, and discloses a preparation method of high-purity crystalline maltitol, which comprises the following steps: firstly, by taking corn starch milk as a raw material, preparing ultrahigh-content maltose syrup with the maltose content of more than or equal to 91%, the wheat triose content of less than or equal to 0.4% and the glucose content of less than or equal to 4% through an enzyme conversion method; carrying out hydrogenation reaction on the syrup by adopting a Raney nickel catalyst, and controlling the hydrogenation side reaction to be 2% or below, so as to obtain hydrogenated liquid with maltitol content of more than or equal to 88%; and then, a pigment separation procedure in a traditional process is omitted, and the hydrogenated liquid is directly subjected to decoloration, ion exchange, evaporation concentration, crystallization, centrifugation and drying treatment to finally prepare crystalline maltitol. According to the method, by screening a specific compound enzyme system and finely regulating the pH value and temperature control environment of a saccharification reaction system, the generation of maltose is effectively promoted, and side reactions such as excessive hydrolysis of glucose and reverse synthesis of trisaccharide are inhibited at the same time, so that the high-purity maltose syrup precursor is obtained.

Systems and methods are provided for improving efficiency and quality of plasma being removed from a blood separation chamber. The system includes a separation chamber in which plasma is separated from cellular blood components, a pump for moving the plasma and an outlet line for removing the separated plasma from the blood separation chamber. An optical sensor assembly is configured to monitor the blood separation chamber and measure an interface position between the separated component and the plasma, and to generate an output indicative of the measured interface position. A controller is programmed to utilize a lipid concentration input of the blood and to set an original lipemia offset, a lipemia threshold and lipemia final setpoint from a predetermined database, and to use a proportional-integral-derivative control loop to assess the actual interface position plus the lipemia threshold to adjust and achieve a final lipemia setpoint for use during separation procedures.
