The content of <TEX>$SiHCl_3$</TEX> as a trace impurity in <TEX>$SiCl_4$</TEX> was analyzed by Near IR spectrophotometer with optical fiber. The strong absorption bands of <TEX>$5345{\sim}5116cm^{-1}$</TEX> and <TEX>$4848{\sim}4349cm^{-1}$</TEX> were used for analysis of <TEX>$SiHCl_3$</TEX>, and the detection limit of impurity <TEX>$SiCl_3$</TEX> was appeared to be 0.005 % in the spectrum. The quantitative analysis by Near IR spectrophotometry showed the analytical possibility of trace impurity in <TEX>$SiCl_4$</TEX> without sample pre-treatment not only in the laboratory but also in the field.
