From the solution of the system of equations (3), we determine η-1 of the most interesting components of the analyzed concentrations of the studied medium.

For the determination of the relative concentration of the output from the depth of the area of the signal, which make up - 9- η-1 parameter, it can be in the range of 600 - 950 nm, for short-circuit protection it is quite acceptable.

If one of the components is known, the separation of the differences between the components and the components is easy, they are easy to install
