Grain analyzer IAS-7500

forageanimal feedoil

Overview
The IAS-7500 is a laboratory near-infrared (NIR) analyzer designed for rapid quantitative and qualitative analysis of granular, powdered and liquid samples. Its compact footprint and large-area scanning mode improve sampling representativeness and spectrum quality, enabling reliable real-time monitoring of sample variability for laboratory benchmark measurements.

Key features

• Fast analysis: multi-indicator results within 1 minute; batch processing suitable for high sample throughput and limited staff.
• Multi-form sample capability: single analyzer supports granular, powder and liquid matrices.
• Large-area scanning mode: enhances representativeness of sampling and improves spectral quality.
• High precision and repeatability for laboratory-standard measurements.

Applications
Feed industry: detection of moisture, protein, fat, fiber (ADF, NDF), protein solubility, starch, acid value and freshness (VBN) in raw materials and finished feed, including pet food and forage.
Grain & oil industry: analysis of protein, fat, moisture, fiber, ash, acid value and peroxide value in cereals, oilseeds, edible oils and by-products.
Flour industry: measurement of moisture, ash, protein, gluten and water absorption in flour.
Chemical industry: organic composition analysis, catalyst development and reaction monitoring, non‑destructive polymer characterization (molecular weight distribution, branching degree, end-group concentration), oil and fuel analysis.
