METHODS FOR PREPARING A DILUTION SERIES

The present invention relates to a first embodiment of a method for preparing a dilution series, comprising the steps a. providing a first sample having a first concentration of a substance and a second sample having a second concentration of said substance, b. injecting a quantity of the second sample to the measuring device and registering at least one response from a measurement, c. altering the concentration of the second sample by adding an amount of the first sample to the second sample, d. injecting a quantity of the second sample generated in step c to the measuring device and registering at least one response from a measurement, e. repeating steps d) and e) until a predetermined number of responses have been registered, said predetermined number of responses being at least three, preferably at least four, more preferably at least eight. The invention also comprises a second embodiment of the method for preparing a dilution series and to a biosensor system arranged to perform the steps of the first or second method.
