The Broadcom online near-infrared analyzer achieves precise monitoring and quality control of key components in agriculture, food, pharmaceuticals, tobacco, and industrial production through real-time and non-destructive detection technology. Its core advantages lie in multi parameter synchronous measurement, real-time feedback, and model optimization. The specific technology and application scenarios are as follows:
1、 Core technical principles
Fundamentals of Spectral Analysis
The instrument emits near-infrared light with a wavelength range of 780-2500nm, which undergoes vibrational absorption with sample molecules (such as C-H, O-H, N-H bonds), forming a unique spectral fingerprint. By detecting the spectral residual image after absorption and combining it with chemometric models such as PLS regression, the composition and content of the sample can be inferred.
Diode array technology
Adopting a durable diode array detector to achieve multi wavelength parallel processing, ensuring stable measurement of moving products (such as samples on conveyor belts) and real-time tracking of process changes.
Model dependency
The accuracy of analysis is highly dependent on the mathematical models established in the early stage. The model needs to be calibrated with a large number of standard samples and regularly updated to adapt to changes in sample characteristics (such as new origin grains).
2、 Core application scenarios
Agriculture and Food Processing
Grain based foods: Real time monitoring of moisture, fat, and temperature during the baking process of cookies, noodles, etc., optimizing drying and frying processes.
Dairy products: Analyze the fat, moisture, and protein in samples such as cheese and milk on the conveyor belt to ensure stable composition.
Leisure food: Measure the moisture, fat, and seasoning content of fried foods, and accurately control the amount added.
pharmaceutical industry
Raw material inspection: Quickly determine the composition and structure of drugs, reducing research and development costs.
Production monitoring: Online detection of active ingredients, uniformity, and moisture in tablets to ensure the quality of each batch.
tobacco industry
Tobacco processing: Real time measurement of moisture, nicotine, and sugar content, without the need to adjust parameters when producing stable mixtures.
industrial production
Petrochemical industry: rapid determination of gasoline octane number and diesel cetane number, optimizing the refining process.
Materials Science: Analyze the composition and properties of materials such as plastics and rubber to support rapid sorting in the recycling industry.
3、 Technical advantages
Real time and efficiency
24-hour continuous monitoring: such as DA7440 ™ Online sensors can be integrated into SCADA systems to achieve real-time multi-component measurement on production lines, reducing waste and rework.
Quick feedback: Complete detection within seconds to minutes, suitable for high-throughput analysis.
Non destructive and environmentally friendly
No chemical treatment is required, avoiding sample damage and waste discharge, in line with the trend of green production.
Multi parameter synchronous measurement
A single test can simultaneously obtain parameters such as moisture, fat, sugar, protein, starch, etc., simplifying the complex sample analysis process.
Model optimization and adaptability
By regularly calibrating and updating the model to adapt to changes in sample characteristics, ensure long-term analysis accuracy.
4、 Limitations and improvement directions
Sensitivity limit
The ability to detect trace components with a content below 0.1% is insufficient, and high-sensitivity techniques such as chromatography need to be combined.
Model Dependency Challenge
A large number of standard samples are required to train the model, and the cost of model updates is relatively high. In the future, model sharing and intelligent optimization can be achieved through artificial intelligence and cloud computing.
Environmental stability requirements
Temperature control (starting at 18-24 ℃), humidity control (<50%), and avoidance of vibration are necessary to maintain instrument performance.
