Summary of the invention
The invention provides a kind of column underwater in-situ on-line analysis probe based on sequential injection, adopt sequential injection method to carry out underwater in-situ detection to realize to water pollutants such as lake, river, reservoirs, and the drawback existing to overcome prior art.
For realizing the object of the invention, this column sequential injection original position analysis probe is characterized in that it comprises the support being installed on a cylindrical shell, on support, be equiped with successively syringe pump, hyperchannel selector valve, clear up reactor and photoelectric detector, prop up top of the trellis and install an end cap, on end cap, be provided with Reagent packaging container, in Reagent packaging container, each reagent container outlet of installing connects respectively the each reagent entrance of hyperchannel selector valve by the road, the public entrance of hyperchannel selector valve joins with syringe pump successively after liquid storage coil pipe and two position three-way valve, one outlet of hyperchannel selector valve connects clears up reactor inlet, another outlet connects photoelectric detector entrance, photoelectric detector outlet connects the discard solution discharge port on end cap by the road, data transmission interface in cylindrical shell on data processing equipment via line and the end cap of installing joins, a waterproof sleeve spins under end cap, the cylinder end, is provided with counterweight.
Described liquid storage coil winding is on a pillar, and the support on described pillar and cylindrical shell is connected.
Described clearing up is equiped with uviol lamp and well heater on reactor.
The technical progress that the present invention obtains: adopt cylindric underwater in-situ on-line analysis probe of the present invention, adopt miniature ultraviolet heating combined digestion device and pick-up unit, greatly reduce the volume of in-line analyzer, instrument entirety is carried out to waterproof sealing design, realized sequential injection method instrument and can drop in water water body is carried out in situ detection.Each measurement reagent consumption is only 80 microlitre～200 microlitres, for 1/4～1/5 of traditional instrument, overcome and in existing environmental monitoring, adopted the in-line analyzer volume of sequential injection method large, big energy-consuming, be unfavorable for installation and maintenance, can not in water body, directly measure and be difficult to realize the defect that water body Real-Time Monitoring, original position are analyzed.Ram pump stepper motor often transfers 0.8 microlitre to, can improve in accuracy of instrument to 5%.Simple and reasonable, have volume miniaturization, lightweight, reagent consumption less, the feature such as measure quick and precisely.Can select to detect wavelength 200nm～900nm according to measured object difference, and according to range ability different choice light path 10mm～50mm.
