Analysis of Amino Acids by KBr Tablet Method

Special care is necessary in order to obtain a satisfactory spectrum by the KBr tablet method, including securing a uniform powder size and maintaining a constant pressure during tablet forming (pelletizing). In particular, the effect of moisture requires special attention. In this experiment, we conducted an analysis of amino acids, which easily absorb moisture, by the KBr tablet method. This introduction also includes an example of failure.
