Abstract
A kind of aerosol sample automatic dilution device, including reservoir portion, dilution part and control part, also includes a sample filter, and reservoir portion includes ultra-pure water storage bottle and sample bottle；Dilution part is divided and is included syringe pump I, syringe pump II, sample filter, threeway blender and electronic two position four-way valves；Control part includes controller and controls connecting line.Controller is connected with syringe pump I, syringe pump II, electronic two position four-way valves respectively by controlling connecting line.After syringe pump carries sample and pure water feeding threeway blender mixed diluting, send into sample collection bottles through electronic two position four-way valves.This utility model filters through sample filter before sample pumps into, and reduces the concentration treating measured ion in sample, improves precision.This utility model simple in construction, easy to operate, practical, low cost.
Description
Technical field
This utility model relates to technical field of analytical chemistry, is specifically related to a kind of aerosol sample automatic dilution device.
Background technology
During for sample analysis such as the dirty atmospheric aerosol of high concentration, lake water, rivers; particulate matter in sample and high concentration usually can impact analysis results; or the selection of impact analysis method; so must analyze after sample is carried out pre-treatment, traditional processing method can introduce ionic soil during implementing, and impacts the result of sample to be analyzed again; make result higher; operating lack of standardization, error is big, and takes time and effort.
Some dirty enriched sample treat that the concentration of measured ion is higher, analyze again after needing dilution, operate when off-line analysis cumbersome, if the suction pipe used in dilution or volumetric flask pollute or do not have wash clean, will result directly in the change of the sample concentration after dilution.
Utility model content
A kind of aerosol sample dilution test device that the purpose of this utility model is contemplated to solve the problems referred to above and provides.
The purpose of this utility model can be realized by following measures:
A kind of aerosol sample automatic dilution device, including reservoir portion, dilution part and control part, reservoir portion includes ultra-pure water storage bottle and sample bottle；Dilution part is divided and is included syringe pump I, syringe pump II, sample filter, threeway blender and electronic two position four-way valves；Control part includes controller and controls connecting line.
Controller is provided with instruction and controls keyboard, LCDs.
Above-mentioned controller is connected with syringe pump I, syringe pump II, electronic two position four-way valves respectively by controlling connecting line.
Above-mentioned ultra-pure water storage bottle is connected with syringe pump I by PE pipe；Syringe pump I connecting tee blender.
