All by peristaltic pump, the two ends of variable quantity tube are connected in the hole of six-way valve two opposition, carry
Liquid pipe one end, sample cell one end, blender, sewer pipe one end remain 4 with six-way valve respectively
Hole connects；The sewer pipe other end is passed through waste liquid bottle；The carrier fluid pipe other end is passed through in carrier fluid；Sample
The pipe other end is connected with automatic sampler；Potassium borohydride pipe one end is passed through in solution of potassium borohydride,
The other end and blender connect, and blender and moisture trap connect, moisture trap top and
Atomizer connects, and atomizer and mass flow device two connect, and mass flow device two is by steady
Pressure valve is connected with trachea；Moisture trap is connected with by peristaltic pump for the pipeline of removal waste fluid；Gas
Water separator bottom is connected with electromagnetic valve；Blender and mass flow device one connect, mass flow
Device one is connected with trachea by pressure maintaining valve.
The beneficial effects of the utility model are:
Use this utility model provide the six-way valve for atomic fluorescence spectrometer and can set
The sampling device that buret combines, is combined eliminated by six-way injection valve and variable quantity tube
Generation-Atomic Fluorescence Spectrometry device and the shortcoming of sequential sample injection device, remain six-way injection valve sample introduction essence
Accurate, facilitate durable advantage, it is achieved that single-point joins standard curve, sample automatic dilution merit automatically
Can, improve precision and the detection limit of instrument, can realize semi-automatic and full-automatic, improve
The service efficiency of instrument and practicality.
