A trial device was made to measure the buffer capacity of foods using a personal computer. This device differs from the conventional analog-treated buffer capacity apparatus, so that the buffer capacity of dilute samples, such as 10-4 mol l-1, can be measured with high stability. The buffer capacity of water is subtracted automatically from that of the sample. The output signal is automatically converted to the buffer capacity value, so that the data obtained can be easily treated. Thus buffer capacity measurement becomes an easy determination.
