Technical Field
The utility model relates to the technical field of chemical detection, in particular to a liquid storage device of a high performance liquid chromatograph.
Background
High Performance Liquid Chromatography (HPLC) is an analytical instrument designed using the principle of high performance liquid chromatography. It is composed of liquid storage bottle, pump, sample injector, chromatographic column, detector and recorder. The mobile phase in the liquid storage bottle is pumped into the system by a high-pressure pump, the sample solution enters the mobile phase through a sample injector and is loaded into a chromatographic column (stationary phase) by the mobile phase, and as each component in the sample solution has different distribution coefficients in two phases, when the two phases do relative motion, the components are separated into single components which flow out of the column in sequence through the repeated adsorption-desorption distribution process in the moving speed, and when the single components pass through a detector, the sample concentration is converted into an electric signal and transmitted to a recorder, and the data is printed in a graph form, so that the analysis precision is high, and the HPLC is applicable to organic compounds with high boiling point, difficult volatilization, unstable heating and large molecular weight, so that the HPLC is widely applied to life science, food science, drug research and environmental research.
When the high performance liquid chromatograph is used, different solvents (such as dichloromethane, acetonitrile and alcohols) can be used in the mobile phase, the solvents can be used after bubbles are removed by ultrasonic treatment, and usually the solvents are replaced in the original liquid storage bottle after ultrasonic treatment, so that a plurality of liquid storage bottles are arranged beside the high performance liquid chromatograph, but the excessive liquid storage bottles and detection analysts are at the same height, and therefore, the risk that the detection personnel knocks over the liquid storage bottles exists.
In the prior art, in order to avoid the detector to influence each other with the stock solution bottle, solve the above-mentioned problem, the designer has designed the top surface of high performance liquid chromatograph and has placed the platform of stock solution bottle, is equipped with the rail all around, prevents that the stock solution bottle from dropping from the top surface of high performance liquid chromatograph, plays certain guard action.
However, the liquid inlet pipe of the mobile phase of the conventional high performance liquid chromatograph is placed in disorder, and the disorder liquid inlet pipe is like a winding wire, so that when an operator carelessly touches the liquid inlet pipe in the operation process, the liquid inlet pipe can pull the liquid storage bottle, and the liquid storage bottle has no fixed structure, so that the liquid storage bottle is toppled over. Particularly when the solvent in the liquid storage bottle is replaced, the method is quite inconvenient.
Disclosure of utility model
The utility model aims to provide a liquid storage device of a high performance liquid chromatograph, which is used for solving the technical problems that a liquid storage platform in the prior art does not fix a liquid storage bottle and does not drain a liquid inlet pipe, so that the liquid storage bottle is easy to topple over due to touching the liquid inlet pipe in the process of replacing a solvent.
In order to solve the problems, the technical scheme adopted by the utility model is as follows: the utility model provides a high performance liquid chromatograph liquid storage device, including the bottom plate, its characterized in that: the liquid storage bottle is characterized in that a backboard is arranged on one side of the bottom plate, a left stand column and a right stand column are arranged on one side of the bottom plate away from the backboard, the left stand column is connected with the backboard through a left transverse plate, the right stand column is connected with the backboard through a right transverse plate, a limiting plate is connected between the left transverse plate and the right transverse plate in a sliding manner, a limiting bolt capable of fixing the limiting plate is arranged on the limiting plate, and an elastic band capable of limiting the liquid storage bottle is arranged on the limiting plate.
The beneficial effects of this embodiment lie in:
In the prior art, a liquid storage bottle is placed on a liquid storage bottle placing platform arranged on a high performance liquid chromatograph, when the liquid storage bottle is replaced, the liquid storage bottle is easy to turn over carelessly, solvent is leaked, glass slag is generated by breaking the liquid storage bottle, but the application designs a limiting plate in sliding connection, and the limiting plate is used for sliding on a transverse plate to tightly prop against the liquid storage bottle, so that the periphery of the liquid storage bottle is supported and is not easy to topple.
Further, the limiting plate is provided with a pin on the upper top surface, and clamping joints capable of being clamped with the pin are arranged at two ends of the elastic band. The clamping structure enables the elastic band to be disassembled according to the needs in use, so that the elastic band can be bundled on the liquid storage bottle.
Further, the limiting plate both ends are equipped with the slider, be equipped with on the diaphragm and supply the gliding spout of slider, the limit bolt is equipped with the threaded rod that runs through diaphragm and slider threaded connection, the threaded rod is connected with the tight rubber piece that supports that can support tight right diaphragm. The thread of the threaded rod is inserted into the sliding block, and the threaded rod drives the abutting rubber block to abut against the right transverse plate to fix the limiting plate.
Further, the limit bolt further comprises a rotary handle capable of screwing the threaded rod. The rotation handle is convenient for operating the limit bolt.
Further, a straight rod is arranged between the rotary handle and the abutting rubber block. If the abutting rubber block is not spaced from the rotary handle, when the abutting rubber block contacts the right transverse plate, the operation space of the rotary handle is small, and the rotary handle is inconvenient to screw.
Further, a guardrail is arranged between the left upright post and the right upright post.
