Abstract
The plasma emission detector (PED) has been shown to be an element spe cific detector for supercritical fluid chromatography (SFC). The commo nly used eluents (CO2 and N2O) tend to disturb the He plasma; two diff erent discharge tubes were tested in an attempt to overcome this probl em. Promising results were obtained with a concentric dual flow torch design for the element specific detection of Cl, H, and C containing a nalytes using N2O as SFC mobile phase.
