Embodiment Construction

[0023] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these examples are used to illustrate the present invention and not to limit the scope of the present invention. The implementation conditions used in the examples can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not indicated are usually the conditions in routine experiments.

[0024] Example Figure 1~4 As shown, the split nanofiber solid phase extraction column includes a sample storage tube 1, the lower end of the sample storage tube 1 is sleeved with a fiber filling tube 2, and the inside of the fiber filling tube 2 is filled with nanofibers as a column filler. The sample storage tube 1 includes upper and lower tapered tubes 11, 12, and the upper and lower tapered tubes 11, 12 are connected into one body through the larger ends of the tapered tubes. The fiber filling tube 2 includ...

Abstract

The invention discloses a split-type nanometer fibre solid-phase extraction column and an application thereof, comprising a sample storage tube (1), wherein a fibre filling tube (2) is sleeved at the lower end of the sample storage tube (1) and nanometer fibre used as a column filler is filled inside the fibre filling tube (2). The extraction column has the advantages that the operation flow is simplified, the enriching efficiency is improved, the operation time is shortened, and the like. Compared with the traditional solid-phase extraction column, the utility model ensures that the use amount of adsorbent is greatly reduced and is convenient and rapid to manufacture and use.

Description

technical field [0001] The invention belongs to the technical field of purification of micro or trace substances, and in particular relates to a split nanofiber solid-phase extraction column and its application. Background technique [0002] Modern analysis technology is developing towards fast, micro, trace, multi-component, and high selectivity. Various new types of precision instruments emerge in an endless stream, and higher and higher requirements are put forward for the sample pretreatment process. However, 60% or more of the analysis operation time is spent on sample pretreatment, and most of the experimental errors come from the sample pretreatment process. Solid-phase extraction (Solid-Phase Extraction, referred to as SPE) is an effective means of separation and purification of trace or trace substances. It is a sample pretreatment technology developed in recent years. It is developed by combining liquid-solid extraction and column liquid chromatography. It is main...
