Fig.10 is the plot of average fpr versus the average training time about EHMM-CT, HSMM in [8] and
FABM in [18].
Straight line distances between
FABM and the major outcrops are as follows (cf.

The technology might be slightly more advanced, but
FABMS have been around for donkey's years.
The corresponding glyco-sulfate conjugates, GSHCA and GSDHCA, also yield singly charged, deprotonated ions at m/z 526.2 and 542.2, but unlike
FABMS, doubly charged ions at m/z 262.8 and 270.8 were also generated.
The purified platycodin D was identified on the basis of Rf,
FABMS (=1225.38), and [13C]-NMR spectra compared with the authentic platycodin D (Figure 1).
FABMS m/z: 280.32 ([C.sub.17][H.sub.16][N.sub.2][O.sub.2]), base peak m/z 182.24 ([C.sub.13][H.sub.12][N.sup.*+]); 203.21 ([C.sub.11][H.sub.11][N.sub.2][O.sub.2.sup.+.]); 104.98 ([C.sub.7][H.sub.7][N.sup.+*]); 77.10 ([C.sub.6][H.sub.5.sup.+.]).
The new compounds 1, 4 and 5 were elucidated due to 1D-, 2D-NMR techniques,
FABMS and HR-FABMS analyses.
ESMS on an Advantage Max LCQ Thermo-Finnigan mass spectrometer and
FABMS were carried out on a JEOL SX 102/DA-6000 mass spectrometer.
In our previous reports, the mechanism of thermal crosslinking reaction of vinyl ether groups with phenolic binder polymers and acidolytic de-crosslinking reaction by photogenerated acids has been studied by such spectroscopic methods as FT-IR, NMR, and
FABMS (22-24).
The structures of isolates were elucidated by the combination of 1D (1H and 13C-NMR), 2D (HMQC, HMBC and COSY) NMR spectroscopy and mass spectrometry (
FABMS, HRFABMS) or in comparison with the literature data in case of known metabolites.
The structures of these isolates (1-7) were established by 1D (1H, 13C), 2D NMR (COSY, HSQC, HMBC) spectroscopy and mass spectrometry (EIMS, HREIMS,
FABMS, HRFABMS).
