	abstract = "The use of the microwave-induced plasma with a new low-flow plasma centering torch has been evaluated. Data were collected through a computer-controlled, background-correcting polychromator system with two versions of the newly developed laminar flow torch. It showed sensitivities slightly better than the 0.5-mm-i.d. capillary quartz open tube torch. Detection limits were between 8 and 60 pg/s for carbon, hydrogen, bromine, chlorine, and fluorine—a considerably improved performance over the tangential flow torch. Torch lifetime and plasma stability are comparable to or better than the high-flow tangential flow torch with three-hour and three-day RSDs of 2% and 6%. Centered plasmas may be sustained with flow rates as low as 5 mL/min.",
