Injection pressure and the quadrupole mass spectrometer vacuum within the relationship also increases linearly,[link widoczny dla zalogowanych], see Table 4.

To get accurate results, be sure to keep a constant calibration and determination of the pressure, otherwise it will increase the measurement error. 4 Conclusion At present, the laboratory analysis system has been put into use, with the algorithm to optimize and improve the database spectrum, the system has achieved accurate detection of various gases.
