Stop Losing Money on NIR: The Calibration Mistakes Costing Feed Mills Thousands NIR calibration mistakes cost food and feed labs time and trust. Learn sample minimums, validation benchmarks, and monitoring protocols that keep models… <p>Calibration failure shuts down NIR programs — not instrument failure. In most cases, the instrument is fine. The model built on it is not.</p> <p>The instrument is just hardware. The calibration model is where the real work happens — and it's where most labs underinvest.</p> <p>I've seen this play out at plants where a perfectly functional instrument sat unused in a corner. Someone built a calibration five years ago on 40 samples. It started drifting. Nobody knew why. Eventually, people stopped trusting it entirely. That's a calibration failure — not an instrument failure. The distinction matters, and it matters before you call the service technician.</p> <h2>The Part Most Operations Managers Get Wrong: NIR Calibration</h2> <h2>How Many Samples Does a Production Calibration Actually Need?</h2> ← Back to NIR Spectroscopy Blog
