This article is specially organized by Shandong Quankeruida Instrument and Equipment, which specializes in sorting out the residual oxygen test information of portable oxygen meter test vials.
With the continuous development of science and technology, portable residual oxygen meters have been widely used in the pharmaceutical industry. As a common form of pharmaceutical packaging, the residual oxygen content of vials is of great significance for the preservation and quality control of drugs. This article will introduce the principle, method and application of portable residual oxygen meter for testing residual oxygen in vials, in order to provide reference for relevant practitioners.
1. The principle of portable residual oxygen meter.
Portable residual oxygen meter is a measuring instrument based on the principle of pressure sensor and oxygen permeability rate, which can accurately calculate the amount of residual oxygen in the vial by measuring the pressure change in the vial, combined with parameters such as temperature and humidity. The principle is that under certain temperature and humidity conditions, the transmission rate of oxygen in the vial is proportional to the pressure in the vial, so the oxygen permeability and residual oxygen amount can be calculated by measuring the change in the pressure in the vial.
2. Test method of portable residual oxygen meter.
1.Preparation: Select a non-destructive and well-sealed vial and calibrate it with a portable residual oximeter to ensure that the instrument is working properly.
2.Measurement environment: The portable residual oxygen meter is placed in a constant temperature and humidity environment to ensure the accuracy of the measurement results.
3.Test process: Insert the probe of the portable residual oxygen meter into the vial, maintain a certain contact time, and wait for the instrument to read and stabilize before recording the data.
4.Data processing: According to the readings displayed by the instrument, combined with temperature, humidity and other parameters, the residual oxygen in the vial is calculated.
3. Application of portable residual oxygen meter.
Portable residual oxygen meters are widely used in the pharmaceutical industry in the following aspects:
1.Drug quality control: By testing the residual oxygen in the vial, it can be judged whether the drug meets the quality standards, and the unqualified drugs can be dealt with in time to ensure the safety and effectiveness of the drug.
2.Drug preservation: The portable residual oxygen meter can monitor the changes in the oxygen content of the drug during storage, which is helpful to detect the deterioration of the drug in time and ensure the quality and safety of the drug.
3.Selection of packaging materials: Testing the air permeability and oxygen permeability of different packaging materials through portable residual oxygen meters can help enterprises choose more suitable packaging materials, improve the preservation effect of drugs and extend the shelf life.
4.Production process monitoring: In the pharmaceutical production process, the portable residual oxygen meter can monitor and record the oxygen content of each process link in real time, which helps to find and solve problems in the production process in time, and improve production efficiency and product quality.
IV. Conclusions. As an efficient and accurate testing instrument, portable residual oxygen meter has important application value in the pharmaceutical industry. By testing the residual oxygen in the vial through a portable residual oxygen meter, the quality and safety of the drug can be effectively guaranteed, and the production efficiency and product quality of the enterprise can be improved. In the future, with the continuous progress of technology and the increase of application demand, portable residual oxygen meters will be widely used and developed in more fields.
