Near-Infrared Organic Composition Analyzers

A near-infrared light source shines onto the sample surface. The light energy at specific wavelengths excites organic molecular bonds — O-H, C-H, and N-H — causing them to vibrate and stretch. This vibration absorbs energy from the light. The more molecules present in the sample, the more light is absorbed. The analyzer measures the absorbed energy and calculates composition values instantly. Each calibration is built against your primary reference method, so NIR results are directly traceable to the lab values your team already trusts.

Online and inline process analyzers measure continuously — like a flashlight pointed at a moving target. There is no button to press. The sensor reports real-time composition values as product moves across a conveyor, through a dryer, or inside an extruder.

Desktop analyzers offer two modes. In continuous mode, the sensor streams real-time values just like a process unit. In sample mode, the operator places the sample on the turntable and presses Measure. The turntable rotates while the sensor scans the sample, calculates the average value, and stops automatically — displaying final results in seconds.
