\begin{abstract}
Within the framework of radioactive waste management, the evolution of
the gaseous composition inside the underground repository structures
must be understood. Indeed, chemical and microbial reactions and
exchanges occur between the rock, the structures and the air. These
processes are studied in the Andra's Meuse/Haute-Marne Underground
Research Laboratory's (URL). Recently, a gas monitoring station ``Flair
soil'' has been designed to monitor the gaseous composition inside this
URL. This station is composed by two analyzers: a quadrupole mass
spectrometer (QMS) which allows to follow the evolution of several gases
and an infrared laser spectroscope (Picarro) providing simultaneous
measurements of CH4, CO2 and CO. Thus, a multivariate calibration method
for the quantitative detection of interfering and non-interfering gases
in a nitrogen matrix has been developed for the QMS. The MS was
calibrated from pure gases in a nitrogen matrix, with known
concentrations and ion currents obtained from the measurement of each
species of gas. This method uses matrix calculations to calculate the
relative concentrations of an unknown gas mixture from the ion currents
measured directly in the MS. The test gases T1 and T2 were used to
assess the accuracy of the method. Daily ion currents are corrected from
theoretical ion currents obtained from calibration coefficients and test
gas concentrations. Some gases are less well quantified due to their low
concentration in the test gases and interferences on the measured
masses. One of the motivations of this study lay in developing an
advanced measurement tool allowing to be low in sensitivity, and thus to
improve the detection and quantification of gases at low concentrations.
The objective of this paper is to propose an analytical method to
measure the gaseous composition with several molecules. This method was
able to detect hydrocarbons, noble gases, sulfides, greenhouse gases,
oxygen, hydrogen, nitrogen in the same mixture.%
