Abstract
The utility model discloses an environment-friendly liquid chromatogram mobile phase solvent bottle for practice thrift and make full use of liquid chromatogram mobile phase, and avoid the extravagant more problem of mobile phase. The interior of the body of the mobile phase solvent bottle near the central area of the bottom has a cylindrical space slightly larger than the solvent inlet filter head. The advantages and the effects are as follows: the cylinder bottle space which is slightly larger than the solvent inlet filter head is arranged in the bottle body close to the central area of the bottom, so that the solvent inlet filter head can still absorb the chromatographic mobile phase under the condition of few mobile phases without bubbles, thereby saving and fully utilizing the liquid chromatographic mobile phase, and being economical and environment-friendly.
Description
Technical Field
The utility model relates to an analytical chemistry instrument tool technical field especially relates to an environment-friendly liquid chromatography mobile phase solvent bottle.
Background
Liquid chromatographs require a solvent bottle for the mobile phase, which typically requires filtration through a 0.45 micron or 0.22 micron filter membrane to remove fine suspended particles or impurities from the mobile phase to avoid clogging of the chromatographic flow path and column. The bottom of the current conventional liquid chromatography mobile phase solvent bottle containing the mobile phase is as large as the top, and when more than one hundred milliliters of mobile phase remains, the solvent inlet filter head begins to be exposed to the air, and once the solvent inlet filter head is exposed to the air, there is a greater chance that air bubbles will enter the liquid chromatography flow path, affecting the results of the running sample. One hundred milliliters of mobile phase can generally analyze a multi-needle sample theoretically, and actually because the diameter of the bottom of a conventional liquid chromatography mobile phase solvent bottle is large, the remaining one hundred milliliters of mobile phase is not good, a flow path is continuously used, bubbles can enter into the flow path, and a few needles are not analyzed without continuously using a chromatography sample. If too much mobile phase is initially formulated, the problem of the last two hundred milliliters of mobile phase may not be present, but there are significant problems that are uneconomical and environmentally unfriendly, especially when the mobile phase requires the addition of high concentrations of high cost additives such as ionic liquids, and when the mobile phase contains toxic or corrosive additives that affect the environment.
Surplus volume is too big to the mobile phase that current conventional liquid chromatogram mobile phase solvent bottle can not normally absorb to and the extravagant more problem of mobile phase, the utility model discloses an environment-friendly liquid chromatogram mobile phase solvent bottle can effectively solve above-mentioned problem.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an environment-friendly liquid chromatogram mobile phase solvent bottle, it is too big to aim at solving the mobile phase surplus volume that current liquid chromatogram mobile phase solvent bottle can not normally absorb to and the extravagant more problem of mobile phase.
In order to achieve the above object, the present invention provides the following technical solutions:
the environment friendly liquid phase chromatographic mobile phase solvent bottle is used for saving and fully utilizing liquid phase chromatographic mobile phase and avoiding the problem of more waste of the mobile phase.
Preferably, a bottle space slightly larger than the solvent inlet filter head is arranged in the bottle body of the mobile phase solvent bottle near the central area of the bottom, and the space is in a cylindrical shape, so that the solvent inlet filter head can be conveniently placed; the diameter of the round bottom of the cylindrical space is 0.5-3.5 cm, and the diameter size can be adjusted according to the size of the solvent inlet filter head; the height of the cylindrical space is 2-5 cm, and the height can be adjusted according to the size of the solvent inlet filter head; the topography of the cylinder is lower than the bottle space with larger inner diameter at the upper part of the bottle, and the cylinder and the bottle space are connected by a gentle and smooth slope, so that the liquid at the upper part can completely flow into the small space at the bottom of the bottle when the liquid level drops.
Preferably, the inner part of the bottle body of the solvent bottle, which is close to the central area of the bottom, has a bottle space slightly larger than the filter head of the solvent inlet, but the shape of the bottom of the outer part of the bottle body of the solvent bottle is the same as that of the bottom of the conventional mobile phase solvent bottle, so that the outer bottom of the bottle body of the solvent bottle has enough size to be normally and vertically placed stably.
The utility model discloses technical scheme's beneficial effect: the area near the bottom in the mobile phase solvent bottle body is provided with a cylinder space slightly larger than the solvent inlet filter head, only a small amount of mobile phase is needed, the solvent inlet filter head can not be exposed in the air, the liquid chromatography mobile phase is saved and fully utilized, and the mobile phase bottle is economical and environment-friendly.
Drawings
Fig. 1 is a schematic diagram of a cross-sectional structure of a mobile phase solvent bottle according to an embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below with reference to the accompanying drawings and examples.
As shown in fig. 1, the utility model discloses an environment-friendly liquid chromatography mobile phase solvent bottle for saving and making full use of liquid chromatography mobile phase and avoiding the problem that mobile phase is wasted more. The mobile phase solvent bottle includes a solvent bottle body 102 and a bottle mouth 101.
The mouth 101 of the mobile phase solvent bottle is a screw mouth or a frosted mouth for covering a bottle cap.
The inside of the body 102 near the center of the bottom has a cylindrical space 105 slightly larger than the solvent inlet filter head 104 for placing the solvent inlet filter head 104, the round bottom diameter d of the cylindrical space is 2 cm, and the height h of the cylindrical space is 3 cm.
The cylinder 105 is lower than the bottle space 106 with larger inner diameter at the upper part of the bottle, and the cylinder and the bottle space are connected by a gentle and smooth slope 103, so that the liquid at the upper part can completely flow into the cylinder space 105 at the bottom of the bottle when the liquid level drops.
The area of the interior of the solvent bottle body, which is close to the center of the bottom, is provided with a bottle space which is slightly larger than the solvent inlet filter head 104, but the shape of the bottom 107 of the exterior of the solvent bottle body is the same as that of the bottom of a conventional mobile phase solvent bottle, so that the bottom of the exterior of the solvent bottle body is ensured to have enough size to be normally and vertically placed stably.
The interior of the flask has a slightly larger cylindrical space near the bottom area than the solvent inlet filter head for placing the solvent inlet filter head, and in the case of a cylindrical space with a round bottom diameter d of 2 cm and a height h of 3 cm, a solvent inlet filter head with a round bottom diameter of 1 cm and a height of 2 cm is still below the liquid level of the mobile phase in the case of only 9 ml remaining in the mobile phase. Therefore, the utility model discloses mobile phase solvent bottle has the function of practicing thrift and make full use of liquid chromatogram mobile phase, and economy is the environmental protection again.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications or decorations can be made without departing from the principle of the present invention, and these modifications or decorations should also be regarded as the protection scope of the present invention.
