Abstract
The device of mobile phase surplus is measured based on weight method the utility model discloses a kind of, including mobile phase bottle and large face plate, mobile phase bottle is placed on large face plate；Placed in mobile phase bottle and liquid suction pipe is placed in mobile phase liquid, mobile phase liquid, liquid suction pipe connection drawing liquid pump；Pressure sensor is set in large face plate.The utility model utilizes balance weighing principle, mobile phase is weighed in real time, when the surplus of mobile phase（Weigh number）During less than setting value, warning message is sent to instrument, instrument is made alarm or halt command, so as to avoid instrument dry running from causing unnecessary damage.
Description
Technical field
The utility model is related to a kind of measure the device of mobile phase surplus based on weight method.
Background technology
In chromatographic apparatus detection, mobile phase is often used, mobile phase needs addition in time, can otherwise damage instrument after being finished
Device.Therefore, the test problems of mobile phase content turn into a problem for needing to solve.
The content of the invention
Technical problem to be solved in the utility model is：There is provided and a kind of the dress of mobile phase surplus is measured based on weight method
Put.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
What the utility model was provided measures the device of mobile phase surplus based on weight method, including mobile phase bottle and weighing holds in the palm
Disk, mobile phase bottle is placed on large face plate；Placed in mobile phase bottle and liquid suction pipe placed in mobile phase liquid, mobile phase liquid,
Liquid suction pipe connects drawing liquid pump；Pressure sensor is set in large face plate.
When the liquid in mobile phase is gradually extracted away, the pressure sensor being arranged in large face plate can be recorded automatically
The weight change of mobile phase, when less than setting value, pressure sensor makes alarm or halt command, so as to avoid instrument air transport
Row causes unnecessary damage.
The beneficial effects of the utility model are：
Using balance weighing principle, mobile phase is weighed in real time, when the surplus of mobile phase（Weigh number）During less than setting value,
Warning message is sent to instrument, instrument is made alarm or halt command, so as to avoid instrument dry running from causing unnecessary damage
Wound.
Brief description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure, 1 drawing liquid pump, 2 mobile phases, 3 mobile phases bottle, 4 large face plates, 5 pressure sensors, 6 liquid suction pipes.
Specific embodiment
As shown in figure 1, the present embodiment provide the device of mobile phase surplus is measured based on weight method, including mobile phase bottle
And large face plate, mobile phase bottle be placed on large face plate；Placed in mobile phase liquid, mobile phase liquid in mobile phase bottle and placed
Liquid suction pipe, liquid suction pipe connection drawing liquid pump；Pressure sensor is set in large face plate.
When the liquid in mobile phase is gradually extracted away, the pressure sensor being arranged in large face plate can be recorded automatically
The weight change of mobile phase, when less than setting value, pressure sensor makes alarm or halt command, so as to avoid instrument air transport
Row causes unnecessary damage.
The above, is only preferred embodiment of the present utility model, is not to make other forms to the utility model
Limitation, any those skilled in the art are changed possibly also with the technology contents of the disclosure above or are modified as equivalent
The Equivalent embodiments of change.But it is every without departing from technical solutions of the utility model content, according to technology reality of the present utility model
Any simple modification, equivalent variations and remodeling that confrontation above example is made, still fall within the guarantor of technical solutions of the utility model
Shield scope.
