NIR takes "non-destructive, fast and versatile" as its core, which meets the modern industry's demand for high efficiency, greenness and intelligence, and drives its wide penetration in agriculture, pharmaceuticals, food and other fields.

1. Absorption of light and molecular vibration

The wavelength range of near-infrared light is 780–2500 nm, corresponding to the overtone and combination vibration energy of chemical bonds in molecules.

Main action bonds: C-H, O-H, N-H and other hydrogen-containing chemical bonds (because their vibration frequency matches near-infrared light).

Absorption characteristics: The vibration of different chemical bonds will absorb light of specific wavelengths, forming a unique "fingerprint spectrum".

Example:

The absorption peaks of O-H bonds in water are at 1450 nm and 1940 nm.

The absorption peaks of C-H bonds in fat are at 1200 nm and 1730 nm.

3. Typical Application Scenarios

Scenario 1: Grain Procurement Sites

Issue: Traditional lab testing takes 4 hours, delaying transaction decisions.

NIRS Solution:

Measure soybean moisture (8–18% range, accuracy ±0.15%) within 30 seconds.

Grade pricing based on protein content (32–39%), avoiding overpayment for low-quality crops.

Scenario 2: Feed Formula Optimization

Issue: Nutritional fluctuations in raw materials cause formula errors, impacting livestock growth.

NIRS Solution:

Real-time analysis of corn starch (60–75%) and wheat gluten (24–34%) content.

Dynamically adjust formulas, reducing nutrient waste by 10–15%.
