Abstract

The invention discloses a filter system and a filter method. The filter system comprises a sample disc and a filter module, wherein the at least one accommodating hole for accommodating a chromatography sample injection bottle is formed in the sample disc; the filter module comprises a first perforated plate and a second perforated plate which are attached to each other, at least one filter membrane is fixed between the first perforated plate and the second perforated plate, a volume tube is arranged in the position, corresponding to the chromatography sample injection bottle, of the first perforated plate, and a liquid inlet and a gas inlet are arranged on the volume tube; a filter port is formed in the position, corresponding to the chromatography sample injection bottle, of the second perforated plate and communicated with the chromatography sample injection bottle, and the volume tube, the filter membrane, the filter port and the chromatography sample injection bottle correspond up and down in position. The filter system is suitable to be matched with the chromatography sample injection bottle of an automatic sample injection system, therefore, by the aid of the filter system, to-be-filtered samples can be filtered conveniently and quickly, the chromatography sample injection bottle can be produced in batches, batch and efficient filtration and transfer of multiple samples can be realized, the operation is very simple, and the filter quality can be guaranteed.

Description

technical field [0001] The invention belongs to the field of instrument analysis, and in particular relates to a filtering system and a filtering method. Background technique [0002] At present, with the improvement of instrument automation level, automatic sampling system is more and more widely used in the instrument analysis industry, and the efficiency of batch processing samples is greatly improved through batch chromatography vials. Each sample needs to be filtered through a membrane filter before being transferred to a chromatographic vial. In the prior art, a needle filter is usually used. First, a medical syringe is used to suck the liquid sample into the syringe needle, and a needle filter is connected to the head of the syringe, and the filtrate is squeezed and transferred to a chromatographic sampling bottle. This process needs to transfer samples twice, which is easy to cause sample loss and is not suitable for small sample preparation; it also consumes a vari...
