Notes:
The inertness of injector inserts and insert packing materials, such as glass or fused silica wool, is tested by a procedure based on split injection and rapid isothermal chromatography. Resulting sharp peaks sensitively reveal peak deformation resulting from adsorptivity, acid/base interaction, and excessive retention power. Degradation of labile components is detected by loss of material and degradation products. Adsorptivity was no problem on injecting 300 ng amounts. Degradation only occurred for raw wools; however, the retention power of some wools seemed unnecessarily high. On injection of smaller quantities, degradation remained similar, but adsorptivity increased significantly.
