How to properly operate and use a texture analyzer to get accurate results?
Texture analyzer is an instrument used to measure the texture properties of materials, which is widely used in food, pharmaceutical, tobacco, chemical and other industriesProper operation and use of the texture analyzer is key to ensuring accurate, reliable results, and below is a detailed description of how to properly operate and use the texture analyzer to obtain accurate results.
1. Preparations.
1.Start-up preparation: Before using the texture analyzer, first make sure that the instrument is in normal working condition, connect the power supply, turn on and warm up to ensure the stable operation of the instrument.
2.Calibrate the instrument: Before use, calibrate according to the instrument manual to ensure the accuracy of the test results, which usually includes steps such as calibration of the load and zero point calibration.
3.Choose the right probe: according to the nature of the test sample and the purpose of the test, choose the right probe, the texture analyzer has different probes, such as cylindrical, conical, spherical, needle, etc., which are suitable for different types of materials.
2. Sample preparation.
1.Prepare the sample: Place the sample in an appropriate container to ensure that the sample is flat and uniformFor solid samples, a knife can be used to cut to the appropriate size;For liquid samples, a dropper can be used to drop the sample onto the test tray.
2.Set sample parameters: According to the characteristics of the sample and the purpose of the test, set the parameters of the texture analyzer, such as test force, test speed, trigger force, etc.;These parameters will affect the accuracy of the results during the test.
Third, the testing process.
1.Sample placement: Place the prepared sample on the sample stage of the texture analyzer to ensure that the sample is stable.
2.Set the test parameters: According to the sample and the purpose of the test, set the test parameters of the texture analyzer, including the test force, test speed, trigger force, etc., which can be adjusted according to the specific sample and test needs.
3.Start the test: Start the texture analyzer and let the probe test the sample according to the set parameters, during the test, the texture analyzer will automatically record data such as force, time and deformation rate.
4.Data collection and analysis: After the test, the texture analyzer will transmit the data to the computer system, and use the corresponding data analysis software to process and analyze the data to obtain the test results.
4. Precautions.
1.Operation specification: When operating the texture analyzer, follow the instruction manual of the instrument to ensure the operation specification.
2.Sample Handling: Ensure that the sample is of good quality, free of contamination and damage, and during the test, avoid touching the sample with your hands so as not to affect the test result.
3.Parameter setting: Set the test parameters reasonably to ensure the accuracy of the test results, and in the actual operation, the parameters can be adjusted according to experience and actual conditions.
4.Data processing: The test data is processed and analyzed by professional software to ensure the accuracy and reliability of the results.
5.Maintenance and maintenance: Regularly maintain and maintain the texture analyzer to ensure that the instrument is in good working condition.
