A radioisotopic light source by
14
C exitation has been made. The radioisotopic light source has been used in photometric analysis. The stability and accuracy of the new photometric system are better than that of the conventional instruments. The data are given directly in digital.
Uranium and iron samples have been measured. For iron detection limit of 0.2µg/ml
detection range of 0.4~100μg/ml and measuring precision is better than ±5%were achieved.
Thes result were consistent with that obtained by using conventional light source.
