Technology & quality control
PURPL PRO
by PURPL SCIENTIFIC
Near-infrared spectral analysis
We use PURPL PRO as a portable analytical tool for internal quality control. Near-infrared spectroscopy turns the interaction between light and a prepared sample into analytical information.
01 / NIR
From light to data
- 01
Prepare
Prepare the sample consistently.

04 / QUALITY CONTROL
Consistency through data
Comparable measurements start with consistent preparation and a repeatable procedure. Digital records make it possible to follow changes over time and identify results that deserve a closer look.
Calibration & validation
Prediction models are developed against laboratory reference measurements. Performance depends on the applicable model, sample preparation and measurement conditions.
Measurement scope & limitations
Portable NIR provides model-based estimates for supported parameters. It does not establish the absence of pesticides, heavy metals or microbiological contamination. Required accredited laboratory testing remains a separate step.
