Onteko develops and applies laser-based elemental analysis systems for seed-level discrimination, classification, and quantitative assessment. We convert elemental signatures into actionable biological and industrial decisions.
Core Capability
We use micro-laser elemental analysis combined with supervised multivariate modeling to convert seed-level spectral data into actionable classification outputs.
Bulk chemical tests provide averages. Optical inspection evaluates appearance. Neither captures classification at the resolution of the individual seed.
Elemental signatures reveal statistically significant discrimination between classes, within-lot variability, and hidden structure not visible optically — enabling evidence-based go/no-go decisions.
Seed Classification & QC
The Laser Elemental Classifier™ performs rapid elemental analysis of individual seeds using a single micro-laser pulse per seed. Each seed generates a characteristic elemental signature, processed by a supervised classification model to assign the seed to a defined class.
Bulk chemical measurements provide averages. Optical inspection evaluates appearance. Neither method captures classification at the resolution of the individual seed. By operating at seed scale, variability becomes measurable and decision criteria become quantifiable.
Process
From seed intake to classification output — a streamlined, traceable analytical pipeline.
Seeds are logged and tracked under controlled conditions. Each seed is evaluated individually — every classification result corresponds to a specific seed.
A precisely controlled micro-laser pulse interacts with the seed surface, generating a transient plasma emission with multi-element spectral information.
Raw spectral data are processed using ProLIBSpector™, performing signal normalization, feature extraction, supervised model application, and class assignment with confidence scores.
Transforms analytical data into structured decision support.
Technology
The Laser Elemental Classifier™ is based on laser-induced breakdown spectroscopy (LIBS), adapted for seed-scale surface verification. The platform builds upon decades of laser spectroscopy development and classification research.
