Flow system based on sequential delivery of air-sandwiched solutions into a micro cell for spectrophotometric catalytic analysis

Enhancement of the Capabilities of Inductively Coupled Plasma Mass Spectrometry Using Monosegmented Flow Analysis

“…A gaseous carrier can also be used to significantly reduce dispersion of the sample plug, resulting in narrower and sharper peaks; however, it leads to significant memory effect as a carrier solution is no longer used to wash out the system. 18,19 To get the best of both worlds, FI into air bubbles of an airsegmented water carrier, [10][11][12][13]19 by switching between air and water carriers 18 or by injecting water and sample plugs into an air carrier, 20 was performed to reduce dispersion while preserving the washing effect of water. The air surrounding the sample plug essentially eliminated the longitudinal dispersion of the sample along the flow path.…”
