Pattern coefficients (PC) of H2O using temperature programmed desorption mass spectrometry (TPDMS) were determined by using TPD curves of m/z 1, 16, 17, and 18 generated from H2O adsorbed on silica gels. TPD curves of m/z 1, 16, 17, and 18, which corresponded to H2O and its fragments were obtained by a quadrupole mass spectrometer (QMS) equipped with the TPDMS apparatus. The H2O pattern coefficients for m/z 1, 16, 17, and 18 were determined to be 16.8, 2.12, 26.4, and 100, respectively. The values were different from those supplied by QMS company especially for m/z 1. Our PC data determined for the TPDMS reasonably explain the TPD curves for CaC2O4·H2O.
