| Abstract: | We analyze the different chloroform gas concentration with Fourier Transformation Infrared spectrum(FTIR) under the different resolution.Combined the US environmental protection bureau(EPA) in the database data with least squares equation to obtain the chloroform concentration under the different resolution,as well as the coefficient of correlation and the relative error.The resolution has some influence on its precision.It is very important to choose the appropriate resolution to enhance the compound precision. |
