An amino acid analyzer having an ion exchange column through which buffer reagents are passed is provided with circuitry means for automatically effecting the various steps of the analysis. The circuitry means being effective to allow continuous automatic supply of samples to the ion exchange column and also to automatically control the elution process, permits uninterrupted continuous operation of the analyzer without the necessity of operator attention. A central timer mechanism effects actuation of a sample supply system to place the sample on the ion exchange column and thereafter the central timer mechanism sequentially activates other timers to automatically control the eluting process. During the eluting process the analysis is carried out in the conventional manner, i.e., using a ninhydrin system and a colorimeter. The colorimeter detects the concentration of amino acids present in the column effluent and sends electrical signals to a recorder mechanism to record or plot the quantity of specific amino acids present in the sample.
