Oxidation induction period analyzer is a common thermal analysis instrument used to measure the thermal stability and oxidation stability of materials. The OIT test method can assess the thermal degradation process of a sample by measuring its oxidation induction period at high temperatures, thus obtaining important information about the stability and durability of the material.

OIT experiments typically use differential scanning calorimetry (DSC), a technique that measures the thermal degradation temperature and reaction rate of a sample under a predetermined oxygen pressure under high temperature conditions. DSC technology is an experimental method based on the thermal response of samples. It is a very reliable measurement method, which can detect the thermal stability and oxidation stability of samples.

The instrument structure of OIT analyzer mainly includes sample heater, differential thermal analysis sensor, test chamber, temperature control device and computer control system. There are also certain steps to run the instrument. First, after the sample is made into a certain size of the gyroscope shape, the instrument is preheated to a certain temperature. At the same time, the atmosphere is pre-set in the instrument so that it reaches the required oxidation pressure, and then the sample is inserted into the test chamber and heated.

During the experiment, the sample will undergo oxidation reaction and release heat, causing the sample temperature to rise. At this point, the differential thermal analysis sensor can measure the heat change of the sample, which is achieved by obtaining the sample temperature through the scanner and analyzing the change in the blue line. According to the thermal degradation of the sample at high temperature, the oxidation induction period of the sample can be calculated.

OIT analyzers have a wide range of applications, especially for studying thermal degradation processes of various polymer materials, and can provide scientists with important information about the stability, performance and service life of materials. In addition, OIT analyzers can also be used in the analysis of other materials and products that require stability and durability information.
