| titleOfInvention | Method, device and system for separating and extracting particles from filter material substrate |
| abstract | The invention relates to a pretreatment method and a pretreatment device for a particulate filter material sample, in particular to a method, a device and a system for separating and extracting particulate from a filter material substrate, which solve the problems that the existing washing method lacks specific implementation details and the existing washing machine is used as a separation device for washing and separating, the particulate loss is large, the separation efficiency is low and the washing by an organic solvent cannot be carried out. The method is characterized in that: step 1: putting the sampled filter material sheet into a separation device, and adding water and a surfactant; the outer layer of the separation device is of a barrel-shaped structure, and the inner layer is provided with a plurality of holes and can rotate; step 2: washing, and enabling turbid liquid to flow out; and step 3: dehydrating, and enabling residual turbid liquid to flow out; and 4, step 4: treating the turbid liquid flowing out from the steps 2 and 3; and 5: returning the processed clear liquid to the separation device, repeating the steps 2 to 4 at least twice, collecting the clear liquid, and collecting the particles on the filter membrane; step 6: the collected clear solution was evaporated at low pressure and the solid residue obtained was put on the step 5 filter. |
