Dear Thanh-Thien Tran-Lam,

I think you should use PyMS or NIST Mass spectral Library Search Program

Here is some advantages of these softwares:

Noise smoothing, baseline correction, peak detection, peak deconvolution, peak integration, and peak alignment by dynamic programming, compounds identification via their own integrated library.

Here is some links to download them (last versions):

PyMS: https://code.google.com/archive/p/pyms/downloads

NIST: https://chemdata.nist.gov/dokuwiki/doku.php?id=chemdata:start

Here is some documents (attached), in which you can learn how to use these softwares.

Best wishes
