Claims
- 1. An analysis apparatus comprising a sample feed duct, at least one reagent feed duct, a sample pump, at least one reagent pump, a reaction channel, a detector, and a controller for controlling the pumps to feed sample and reagent into the reaction channel as a block, wherein each pump has a delivery amount which is individually controllable and wherein the controller is operative to control the pumps to feed sample and reagent into the reaction channel alternatingly to form sample and reagent segments substantially shorter than the length of the block.
- 2. An analysis apparatus as in claim 1 wherein a local volume ratio between sample and reagent, averaged over a reaction channel section of predetermined length, is substantially constant along the length of the block.
- 3. An analysis apparatus as in claim 1 wherein each pump is a piston pump driven by a separate d.c. or stepper motor.
- 4. An analysis apparatus as in claim 1 wherein the detector has a detector volume which is smaller than the volume of a reaction core within the block.
