Abstract
The utility model discloses a kind of novel solid extraction columns, column tube including being located at upper end, and the collecting pipe below column tube is connected to, the sieve plate filter membranous layer for filtering is provided in column tube, column tube is provided with collecting pipe junction for the relief hole of balancing Atmospheric pressure.The novel solid extraction column of the utility model can once complete large volume loading, moreover it is possible to filter out bulky grain solid impurity by on-line filtration device, fully ensure that the clean-up effect of determinand.
Description
Technical field
The utility model is related to chemical experiment device field, more particularly to a kind of novel solid extraction column.
Background technology
Solid-phase extraction column (SolidPhaseExtractionColumn, abbreviation SPEcolumn or
SolidPhaseExtractionCartridges, abbreviation SPEcartridges), it is a kind of use developed from chromatographic column
In the sample pretreatment device of extraction, separation and concentration.Nowadays, solid phase extraction techniques have been used extensively in many national standards
(GB/T) and in industry analysis standard.In chemical analysis technology, solid phase extraction techniques are developed in the seventies in last century, by
Have many advantages, such as that convenient, efficient, reliable, consumption reagent is few in it, formed in many fields instead of traditional liquid-liquid extraction
For the effective means of sample pre-treatments, it is widely used in analytical chemistry sample pre-treatments.
Well known solid-phase extraction column specification is 3mL and 6mL common-use sizes, and actual experiment operator is using solid phase to extract
When taking column purification test analyte, applied sample amount is frequently more than 6mL, leads to repeatedly loading repeatedly.And since test analyte lacks
Effective in-line purification means frequently result in solid-phase extraction column in analysis purification process and block, reduce analysis efficiency.
Utility model content
The purpose of this utility model is to overcome above-mentioned conventional solid extraction column applied sample amount is insufficient and can not on-line filtration
The drawbacks of purifying determinand, provides a kind of novel solid extraction column, can not only once complete large volume loading, moreover it is possible to by online
Filter device filters out bulky grain solid impurity, fully ensures that the clean-up effect of determinand.
To achieve these goals, the embodiment of the utility model is：
A kind of novel solid extraction column, including the collecting pipe for being located at the column tube of upper end and being connected to below the column tube,
The sieve plate filter membranous layer for filtering is provided in the column tube, the column tube is provided with to balance with the collecting pipe junction
The relief hole of atmospheric pressure.
Preferably, the column tube includes upper column tube and diameter is less than the lower column tube of the upper column tube, the sieve plate filter membrane
Layer is set to the upper column tube and the lower column tube junction.
Preferably, the connection mode of the lower column tube and the collecting pipe is thread fitting.
Preferably, the connection mode of the lower column tube and the collecting pipe is the cooperation between hook.
Compared with prior art, the beneficial effects of the utility model are：
The utility model can once complete large volume loading due to setting column tube；It is provided in column tube for filtering
Sieve plate filter membranous layer falls bulky grain solid impurity by sieve plate filter membranous layer on-line filtration, ensure that the clean-up effect of determinand；In column
Pipe is provided with collecting pipe junction for the relief hole of balancing Atmospheric pressure, is passed through, will not occurred with ensureing to collect liquid energy
The phenomenon that solid-phase extraction column blocks in purification process is analyzed, improves analysis efficiency.
Description of the drawings
Fig. 1 is the structure diagram of the novel solid extraction column of the utility model embodiment.
Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but do not form the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
Please refer to Fig. 1, the novel solid extraction column of the utility model, including being located at the column tube 3 of upper end and being connected to institute
The collecting pipe 5 of 3 lower section of column tube is stated, the sieve plate filter membranous layer 4 for filtering, the column tube 3 and the receipts are provided in the column tube 3
5 junction of collector is provided with the relief hole 6 for balancing Atmospheric pressure.
The column tube 3 includes upper column tube 2 and diameter is less than the lower column tube 1 of the upper column tube 2, the sieve plate filter membranous layer 4
It is set to the upper column tube 2 and lower 1 junction of column tube.
In the present embodiment, the fit system mutual by screw thread 7 of the lower column tube 1 and the collecting pipe 5 connects
It connects, it also can be with passing through the mating connection between hook.When hook is used to connect, just had between collecting pipe 5 and lower column tube 1 flat
The gap of weighing apparatus air pressure, relief hole 6 without setting with regard to also can guarantee that filtrate smoothly flows down at this time.
The utility model is existed due to being provided with the sieve plate filter membranous layer 4 for filtering in column tube 3 by sieve plate filter membranous layer 4
Line filters out bulky grain solid impurity, ensure that the clean-up effect of determinand.It is useful in column tube 3 and the setting of 5 junction of collecting pipe
In the relief hole 6 of balancing Atmospheric pressure, passed through with ensureing to collect liquid energy, will not occur to analyze solid-phase extraction column in purification process
The phenomenon that blocking, improves analysis efficiency.
The embodiment of the utility model is explained in detail, but the utility model is not limited to be retouched above in association with attached drawing
The embodiment stated.For a person skilled in the art, it is right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the scope of protection of the utility model.
