Abstract

The invention discloses a multi-channel pin type filter device which comprises an injector, a filter, a positioning slot plate and a sampling bottle base plate, wherein a positioning bracket and two rows of injector positioning slots are arranged on the positioning slot plate. 5 to 15 slots are arranged on each row of the injector positioning slots. The injector positioning slot is a U-shaped groove and the injector is grafted in the injector positioning slot. The positioning slot and at least two rows of sampling bottle bases corresponding to the positioning slot are arranged on the sampling bottle base plate. The positioning bracket is spliced with the positioning slot. The multi-channel pin type filter device of the invention can simultaneously filter various samples, saves time and labor for filtering and has high efficiency.

Description

technical field [0001] The invention relates to a needle filter, in particular to a multi-channel needle filter device. Background technique [0002] In analytical chemistry, precision instruments such as liquid chromatography and ion chromatography need to be filtered with a needle filter before sampling, otherwise it will easily cause blockage of the chromatographic column, shorten the service life of the chromatographic column, and may also bring in a large amount of interfering substances . The needle filter includes a syringe, and a filter is connected to the front end of the syringe. The filtration method is to use the syringe to inhale the sample, connect the filter, and pressurize the liquid by hand to make the liquid pass through the filter membrane and enter the sample bottle to complete a sample. filter. When the number of samples is large, it will be found that this kind of filtering one by one is very time-consuming and laborious, and the efficiency is very lo...
