Abstract
A method and apparatus for chemical analysis is disclosed that uses a sample cup insert. The insert is pre-coated with a reaction agent, enzyme, or chemical to facilitate testing of the sample. A sample fluid in the sample cup is agitated by fluid pulsing to speed the reaction or to speed a pre-conditioning step.
Claims38
A method, comprising:
- dispensing a fluid into a sample cup using a sample probe;
- agitating the fluid in the sample cup by using fluid pulsing.
A discrete analyzer, comprising:
- a controller configured to direct a sample probe such that a fluid is dispensed into a reaction cup;
- the controller configured to agitate the fluid in the reaction cup by:
- (a) drawing a portion of the fluid back into the sample probe;
- (b) and then forcing the portion of the fluid in the sample probe back into the reaction cup after a preset time.
1 more element
A computer program, when executed on a processor in a discrete analyzer, configured to cause the discrete analyzer to:
- dispense a fluid into a sample cup using a sample probe;
- agitate the fluid in the sample cup by using fluid pulsing.
A discrete analyzer, comprising:
- means for holding a fluid to be tested;
- means for dispensing the fluid to be tested into the holding means;
- means for agitating the fluid to be tested in the holding means by using fluid pulsing.
