Abstract:
1. An apparatus for continuous, constant, flow sample introduction, comprising: (a) at least one sample line having at least one sample fluid; (b) at least one sampling system for processing said at least one sample fluid; (c) at least one electronic pressure controller for processing at least one carrier fluid; and (d) at least one first sampling valve and at least one second sampling valve, wherein said first sampling valve is connected to said second sampling valve in series, and wherein said first sampling valve and said second sampling valve are configured such that while said first sampling valve is processing said fluids to be analyzed the second sampling valve is being replenished with fluids to be analyzed to provide continuous flow sample introduction to an analyzer and wherein said fluids to be analyzed comprise said at least one sample fluid and said at least one carrier fluid.
