A new detector for fully automatic peptide synthesis.
A new method of monitoring the rate of reactions in solid phase peptide synthesis is described. A conductivity detector in the reaction cell enables the deprotection, washing, and subsequent coupling stages to be examined in detail. The half lives of the reactions can be calculated and hence the optimum reaction times predicted. The aggregation of peptide chains and subsequent collapse of the resin is observed. Difficult sequences are sensed and appropriate action taken completely automatically.
