approximate movement of the plunger during packing is 40 mm. The diagram (Figure 1) is to scale, except for the O-rings, valves and tube fittings. Packing with this system wassatisfactoryexcept when we failed to add enough packing material to fill the column completely, or when the stirring bar fail
## Abstract The technical PCB mixtures Aroclol and Clophen have been analyzed by packed column supercritical fluid chromatography using negative temperature programming. The chromatographic method was successfully applied to the analysis of PCBs, polycyclic aromatic hydrocarbons, and polychlorinate
The elution temperatures and degree of separation of a model system series of hydrocarbons were followed as functions of the rate of temperature programming and carrier gas velocity. Graphs are presented that permit individual assessment of these variables. Lower elution temperatures can be achieved
