Abstract
The invention provides an automatic diluting device of an aerosol sample. The automatic diluting device comprises a liquid storage part, a diluting part and a control part and further comprises a sample filter, wherein the liquid storage part comprises an ultra-pure water storage bottle and a sample bottle; the diluting part comprises an injection pump I, an injection pump II, a sample filter, a three-way mixer and an electric two-position four-way valve; the control part comprises a controller and a control connection line; the controller is connected with the injection pump I, the injection pump II and the electric two-position four-way valve respectively through the control connection line; the injection pumps carries and conveys samples and water into the three-way mixer for mixing and diluting; and then the samples and the water are conveyed into a sample collection bottle. Before the samples are pumped, the samples are filtered through the sample filter, so that the concentration of ions to be detected in the samples is reduced and the precision is improved. The automatic diluting device is simple in structure, convenient to operate, strong in practicability and low in cost.
Description
Technical field
The present invention relates to technical field of analytical chemistry, be 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.
Summary of the invention
