ABSTRACT:
In one embodiment, the present method includes the steps of introducing a volume of a sample into a vapor delivery line and volatilizing at least a portion of the volume as it is carried through the vapor delivery line. At least a portion of the volatilized volume contacts a sensor element, which produces a signal that is monitored to reveal information about the sample. All components upstream of the sensor element are substantially free of sorbent materials so that the sample volume does not contact a substantially sorbent material before contacting the sensor element.
