It is well known that many liquid stationary phases for gas chromatography have a tendency to bleed at high temperature and/or at high flow rate. This problem is especially important in preprative applications, since the liquid phase may then be the contaminant of a pure component. Such contaminant can hardly be deteced by gas chromatography. However, for routine spectral analysis it may introduce certain extraneous peaks in both infrared and nuclear magnetic resonance spectra of the pure component. Consequently, it is desirable to have handy references to avoid misleading by those peaks.
