Polyamide Layer Chromatography XIV Aspect on Quantitative Analysis

Abstract Ten common dinitrophenyl amino acids were used to test the performance of polyamide layer chromatography for quantitative analysis. The polyamide layer is used as the stationary phase and U. V. photometric method is employed for quantitative estimation. The results show that high accuracy of quantitative analysis by polyamide layer can be achieved. Possibility of repeated use of polyamide layer was discussed also.
