The IR Oil Meter is a professional testing instrument based on infrared spectroscopy technology, and its core working principle involves the interaction of infrared light with the sample to be tested. The scattering of transmitted light in IR oil meters can be explained in the following aspects:
The infrared oil meter utilizes the absorption characteristics of oil substances to specific infrared wavelengths, and accurately determines the concentration of oil pollutants in the sample by measuring the absorbance of the sample in a specific wavelength band.In this process, infrared light is first emitted and travels through the sample and then interacts with the oil contaminant molecules in the sample.
Transmitted light: When infrared light passes through a sample, part of the light passes directly through the sample without being absorbed or scattered, and this part of the light is called transmitted light. The intensity of the transmitted light is related to the concentration of oil contaminants in the sample, as the oil contaminants absorb some of the infrared energy.
Scattered Light: Scattering is a phenomenon that occurs when light encounters an inhomogeneous medium. In infrared oil meters, light scatters when infrared light encounters oil droplets, particles, or other inhomogeneous structures in the sample. The direction and intensity of the scattered light depends on the nature, size and distribution of the scatterer.
While infrared oil meters rely primarily on the intensity of transmitted light to measure the concentration of oil contaminants, scattered light also provides some useful information.For example, the presence of scattered light can indicate the presence of inhomogeneous structures or particles in the sample, which can help determine the homogeneity and purity of the sample.However, in the practical application of infrared oil meters, the scattered light is usually not the main measurement object, but is considered as auxiliary information.
In order to accurately measure the intensity of transmitted light and to minimize the interference of scattered light, infrared oil meters usually employ the following measures:
Optimized sample processing: With proper sample pretreatment and extraction steps, the number of inhomogeneous structures and particles in the sample can be reduced, thus reducing interference from scattered light.
Use of high-precision sensors: High-precision sensors measure the intensity of transmitted light more accurately and reduce the effect of scattered light on the measurement results.
Adoption of advanced data processing techniques: Processing and analyzing the measurement data through algorithms and calibration curves can further reduce the interference of scattered light on the final results.
In summary, transmitted light in IR oil meters interacts with oil contaminant molecules as it passes through the sample, while scattered light is a phenomenon that occurs when light encounters an inhomogeneous medium.Although scattered light is not the primary measurement in an infrared oil meter, it provides some useful secondary information.In order to accurately measure the concentration of oil contaminants and to reduce interference from scattered light, infrared oil meters usually employ measures such as optimizing sample handling, using high-precision sensors and employing advanced data processing techniques.
