A processing method of eliminating noises from chromatographic signals based on wavelet transform has been put forward. Through processing of concrete data

it shows that the said method can successfully eliminate noises from chromatographic signals

creating conditions for carrying out accurately chromatographic analysis. At the same time

software design for realizing noise elimination technology based on wavelet transform has been made

using three kinds of software

i.e. VB

Componet Works

and Matlab

for hybrid programming

making the programme to be simple

and interface to be friendly.
