Apparatus and method for controlling centrifugal separator and centrifugation simulation method and centrifugal separator

An apparatus for controlling a centrifugal separator having simulation function of centrifugation condition in said centrifugal separator, comprising:

• means for incorporating parameters for the current centrifugation operation during centrifugation as a part of parameters of said simulation;
• means for executing said simulation function for two times or more by changing time parameters used for simulation of said centrifugation condition at an adequate interval;
• means for determining whether or not result for each execution of said simulation function is substantially identical with the result obtained by execution of said simulation function, using centrifugation condition already established as centrifugation method of substantially equal specimen as parameters;
• means for calculating operating time to obtain said identical separation results;
• and
• means for generating a signal for controlling operation of said centrifugal separator based on said means for determining.

A method for controlling a centrifugal separator, comprising the steps of;

• inputting centrifugation condition already established as centrifugation method of said specimen, when centrifuging a specimen by a centrifugal separator, before starting centrifugation or during centrifugation as first parameters;
• executing simulation of centrifugation condition using said first parameters,
• inputting centrifugation condition to be used when said specimen is centrifuged by said centrifugal separator as second parameters;
• executing simulation of centrifugal separation using said second parameters;
• comparing the results of said simulation obtained by the use of said first parameters and said second parameters to determine whether or not these two results have become identical with each other or to calculate operating time when these two results will be identical with each other;
• and
• generating a signal for controlling operation of said centrifugal separator in accordance with the determining step or calculating step.

A method for simulating centrifugation, comprising the steps of:

• mounting an attachment for analysis and a rotor for analysis on a centrifugal separator, on which the attachment for analysis can be mounted, and placing a specimen on said rotor for analysis;
• starting operation of said centrifugal separator;
• simulating centrifugation according to predetermined centrifugation condition and other information;
• optically analyzing said specimen using said attachment for analysis;
• and
• correcting parameters to be used for said simulation by the use of data obtained as the result of said analysis.
