NIR Spectroscopy Course Curriculum — 32 Lessons, 8 Weeks

The complete curriculum for the NIR Spectroscopy Fundamentals course. Vendor-neutral training designed for food scientists, grain elevator operators, feed mill quality teams, dairy processing professionals, and analytical lab technicians.

Week 1–2: How Near-Infrared Spectroscopy Works

Light-matter interaction, molecular vibrations, the Beer-Lambert relationship, and why organic molecules absorb at specific wavelengths in the near-infrared range. Instrument components — light sources, wavelength selectors, detectors. Why spectroscopy needs chemometrics. By the end of these two weeks you can explain, without a textbook in front of you, why a moisture reading changes when a sample warms up.

Week 3–4: Applications in Food, Grain, Dairy, and Feed

Moisture, protein, fat, starch, and fiber measurement across grain receiving, dairy intake, feed milling, and food manufacturing. When the technology replaces wet chemistry and when it cannot. Industry-specific case studies from real operations. Each application module works through a real specification range — grain protein targets, dairy fat standards — so the numbers aren't abstract.

Week 5–6: Calibration Development and Chemometrics

PLS regression from first principles. Building calibration sets, handling outliers, understanding RMSECV, RMSEP, R², and RPD. Avoiding overfitting. Validation against reference laboratory methods. This is the module students say changes how they read an instrument's software output — the statistics stop being a black box.

Week 7–8: Sample Preparation, Troubleshooting, and Career Applications

Sample presentation and particle size effects. Diagnosing calibration drift, baseline shifts, and model failures. Professional decision-making with near-infrared data. Instrument standardization across multiple analyzers. The final week closes with a decision framework for when to trust an NIR result versus when to send a sample to the reference lab.

Industry-Specific Applications Covered

• Grain Elevators and Oilseed Processing — protein, moisture, starch at intake
• Dairy Processing — fat, protein, lactose from raw milk to powder
• Feed Mills and Pet Food — ingredient verification and finished product QC
• Food Manufacturing — moisture, fat, protein for label compliance
• Flour Milling — wheat protein, ash, and moisture control
• Calibration and Chemometrics — PLS, model validation, drift detection
• Laboratory Guide — FT-NIR vs dispersive vs filter instruments
