Quantitative analysis of multicomponent mass spectra
We present a method for the decomposition of mass spectra of gas mixtures together with the relevant calibration measurements. Only the consistent use of calibration measurements, though noisy, provides sufficient information to overcome this otherwise highly underdetermined problem. For the example of the mixture of three carbon hydrates the feasibility of the procedure will be demonstrated, exploiting singular value decomposition of the cracking matrices. Knowing neither the cracking pattern nor the concentrations of the contributing molecules, the algorithm provides both in the form of expectation values together with error margins.
