Problems solved by technology

Most of the current liquid-phase biochemical analysis instruments require the pre-operation of adding samples. Some imported autosamplers are often complex in structure and expensive. In the process of actual sample analysis, they often rely on manual operation to inject samples.
In the process of biochemical analysis of liquid phase samples, it is difficult to ensure the consistency of the analysis results considering the proficiency of the operator and the deviation of personal perspective

Embodiment 1

[0036] This embodiment is based on the liquid micro-sampling method of thermal expansion of air, comprising the following steps:

[0037] 1. Use an electronic balance to measure the mass of the surface acoustic wave sensor, denoted as m 1 , and then embed the sensor in the bottom of sampling cup 1.

[0038] 2. Use the syringe 5 to extract the sample liquid to be tested, turn the sampling cup 1 upside down, use the syringe 5 to inject 1ml of the sample liquid into the sample cavity 31 of the sampling cup with a volume of 1.5ml, pull out the syringe 5, and place the sampling cup 1 upright ;

[0039]3. Place the sampling cup 1 in the detection chamber 6, insert it on the sensor detection base 63, control the mechanical telescopic arm 62 to wrap the heating plate 61 around the sampling cup 1, and control the heating temperature of the heating plate 61 to rise from 25°C to 37°C °C, as the air pressure expands, the liquid in the sample chamber 31 flows out; the volume V of the sam...

Abstract

The invention discloses a device and a method for liquid trace sampling based on air thermal expansion. A liquid sampling cup is arranged as a core part of the device; sample liquid is injected into the sampling cup of the device and the liquid level reaches appointed height; air and sample liquid exist in the sampling cup; the air in the cup is thermally expanded in the manner of heating the sampling cup; a small hole is formed in the bottom of a cup body; the sample liquid in the cup flows out of the small hole in the bottom under the effect of air expansion; the volume of the sample liquid in the device can be adjusted by controlling the heating target temperature and rate. A slot is formed in the bottom of the cup, and a sensor can be embedded into the slot for detecting the related characteristics of the sample liquid. The device and the method for liquid trace sampling provided by the invention are simple and are low in cost, and the automatic control and the consistency of trace sampling can be ensured.

Description

technical field [0001] The invention relates to a liquid micro-sampling technology, in particular to a liquid micro-sampling device and method using air thermal expansion pressure as power. Background technique [0002] The continuous deepening of research in the fields of biochemistry has led to the emergence of a number of biochemical analysis instruments, among which the biochemical analysis instruments for liquid samples account for a considerable proportion. Most of the current liquid-phase biochemical analysis instruments require the pre-operation of adding samples. Some imported autosamplers are often complex in structure and expensive. In the actual sample analysis process, they often rely on manual operation to inject samples. In the process of biochemical analysis of liquid phase samples, considering the proficiency of operators and the deviation of personal perspective, it is difficult to ensure the consistency of analysis results.
