On-line ultrasonic emulsification sample pretreatment
Category:
Key words:
•The use of general automatic sampler sampling instruments and equipment in the water in the case of particle precipitation or suspended solids more, the results are prone to deviation. Total phosphorus, total nitrogen, COD, permanganate index, and soil samples containing colloids were particularly evident, and the samples taken were underrepresented. Using ultrasonic emulsification device, the sample becomes a uniform and stable liquid before sampling and analysis, and then sampling and analysis, the accuracy of the results is greatly improved, and the actual situation can be more accurately reflected.
•Strong ultrasonic emulsification of the sample, the suspended particles are crushed to a certain number of meshes, very small particle size, the minimum size can reach 50-200 mesh (75 microns), the sample injection system will not be blocked and prevent the formation of large particles wrapping phenomenon
• Suspended sand particles have high hardness and will puncture the peristaltic pump tube and cause damage to the peristaltic pump roller. The ultrasonic emulsification device will peel off other suspended substances attached to the sand particles, and the sand particles will not enter the system after settling.
• Strong ultrasound breaks the algae cell wall, and the cytoplasm flows into the water body to be measured.
• The sample is in an emulsified state at the time of injection, and the aspirated sample is representative
Standard configuration sample position 100 X11ml, can be customized according to the user's sample cup volume requirements sample plate and software to adjust the displacement
• Random injection; multiple sampling measurements on the same sample
1-4 injection needles can be installed, four needles can be injected at the same time, and all channel samples are ultrasonicated
• Ultrasonic power continuously adjustable, according to different samples to adjust, to achieve the optimal effect; maximum power up to 5w/mm2
