固态发射器（814 nm）的输出功率稳定性非常高，当使用两个1.5 V电池时，配备这种发射器作为光源的吸收光度计可以用于测量低至1.5 × 10−4的吸收率。钼蓝法测定磷的检出限为15 ng l− 1。
The stability of the output power of a solid-state emitter (814 nm) is so great when operated from two 1.5-V batteries that an absorption photometer equipped with this emitter as light source can be used to measure absorbances down to 1.5 × 10−4. A detection limit of 15 ng l−1is obtained for the determination of phosphorus by a molybdenum blue method.
