Meaning of analyte
WebThe meaning and purpose of spike-and-recovery assessment In spike and recovery, a known amount of analyte is added (spiked) into the natural test sample matrix. Then the assay (here assumed to be ELISA) is run to measure the response (recovery) of the spiked sample matrix compared to an identical spike in the standard diluent. WebTitration is a laboratory technique used to determine the concentration of a solution by reacting it with a known volume and concentration of another solution. This is done by carefully measuring out a specific volume of the first solution, called the titrant, and adding it to the second solution, called the analyte, until the reaction is complete.
