A new type of UV/VIS liquid-core optical fiber long lightpath absorption system, which was designed as an accessory and spectrum range was extended to UV with minimum wavelength 220 micrometer to compatible with conventional UV/VIS spectrophotometer, was described with high assembling precision RSD 1.4% and absorption 1 to approximately 700 cm for choice. The coupling between source light radiation and liquid-core optical fiber was tested and optimum condition was obtained. The samples introduction was presented and UV transmission spectra of optical fiber was detected. The system was applied to detect elements Cd(II), Pd(II), F-1, Cr(VI), Cu(II), Fe(II), Ti(IV), Pt(II) and medicines Carbamazipine and Vitamin E by using of 105 cm long LCOF, and sensitivities were 42 to approximately 158 times as much as those by 1 cm conventional cell in length, detection limits (3(sigma) ) 0.14 to approximately 17 ng/ml, relative errors less than 11.2%, and recoveries 94 to approximately 102%.
