Problems solved by technology
Among them, the vacuum filtration device generally uses an AC vacuum pump, which requires an AC voltage of 220v, so it is bulky and inconvenient to use in the field; and the suction filtration bottle is mostly a glass device, and the minimum capacity is generally around 250ml, which is inconvenient to carry in the field , in addition, using the same suction filter device between different samples will also cause cross contamination between samples
Although the manual suction filtration device does not need power and is easy to carry, when the sample volume is large or the particle content is high (such as solid digestion liquid such as soil and food), this suction filtration method is very time-consuming and laborious, which brings a lot of trouble to the sample pretreatment. the inconvenience

Abstract
The invention discloses a portable multi-stage suction filtration system, which comprises a sealed portable suction filtration tube which can be connected with a portable heavy metal analyzer. The upper part of the portable suction filtration tube is provided with a sample inlet and a suction filter port. Below the suction filter port, the suction filter port is connected to a DC micro-vacuum pump through the suction filter connection tube, the sample inlet is connected to a multi-stage filter through a sealed connection tube, the multi-stage filter is connected to a sampling tube, and the sampling tube is connected to a sample cup. It is used together with a portable heavy metal analyzer, and is suitable for the suction filtration of sewage samples and solid digestion solutions in the field real-time detection of heavy metals.
Description
technical field [0001] The invention relates to the technical field of suction filtration devices, in particular to a portable multi-stage suction filtration system. Background technique [0002] In recent years, heavy metal pollution is seriously threatening our health. Incidents such as water quality heavy metal pollution, soil heavy metal pollution and rice cadmium pollution have occurred one after another, making heavy metal pollution monitoring and treatment the focus of my country's current pollution control work. [0003] The existing developed portable heavy metal analyzer can be used for real-time detection of heavy metals that may be polluted in the field, and it can detect up to 15 types of heavy metals. The detection principle of this portable heavy metal analyzer is anodic stripping voltammetry. This method requires that the water sample to be tested has no macromolecular pollutants, otherwise it may lead to deviations in the detection data. However, in the act...
