In order to analyze the concentration of cetylpyridinium chloride(CPC), a widely used cationic surfactant, we developed a simple and compact spectrometer, which consisted of a diode laser and a photodiode detector. Preliminary results are described here on the performances of the system in terms if the stability of output intensity, sensitivity, and reproducibility. Data on the comparisons of the system with the conventional UV-VIS spectrometer are also given. With the instrument, the concentration of CPC between 3${\times}$10$^<$TEX>-5/M and 1.1${\times}$ 10$^<$TEX>-4/M are calibrated as a correlation coefficient of 0.9635. The results shown here indicate a potential for developing a portable spectrometer useful for analyzing concentrations of CPC.

제안 방법
And also evaluate its performances, comparing data of the developed system (Diode Laser-Double Beam Colorimetric System, DL-DBCS) with those of the UV/V1S spectrometer.
Since the emitting wave-length is agreed with the absorption maximum of blue colored CPC, ternary chelate compound of CPC with BPR and strontium, the developed system was applied to the analysis of CPC.
대상 데이터
This system features a diode laser, a double beam system, and a photodiode detector. The 633 nm diode laser (LDM 145/633/5, Imatronic Co., Ltd., USA) was used. The laser beam was focused by a convex lens (F.
