New injection technique for flow injection atomic absorption spectrometry using tubing clamp valves.
Flow injection devices for atomic absorption spectrometry usually are equipped with a sixport-valve consisting of two PTFE-cylinders. This kind of valve can be substituted by an arrangement of tubing clamp valves. The advantages and limits of this new injection technique for flow injection atomic absorption spectrometry are discussed.
