Real industrial applications of spectroscopy intelligence — from field trials to live operational deployments.

Methanol Detection & Alcohol Composition Quantification

Methanol Detection and Alcohol Analysis
Operational Chemical & Public Safety Device: IDIR LA20

Detecting methanol adulteration in hand sanitizers and alcoholic products is a critical public health challenge. Lab-based FTIR systems are accurate but expensive, slow, and laboratory-bound. IDIR deployed the LA20 portable liquid analyser for on-site screening with immediate results.

Challenge

  • Methanol contamination in consumer alcohol products poses serious health risk
  • Lab-based methods are slow and cannot screen at-market or at-point-of-import
  • High percentage of sub-standard products found in Malaysian market

Spectroscopy Approach

  • NIR spectroscopy via IDIR LA20 portable liquid analyser
  • 5-component quantification model: Methanol, Ethanol, Isopropanol, n-Propanol, Water
  • Field-tested with real-world Malaysian market samples
  • On-site testing with immediate results — no sample prep required

Validation

  • Model correlated against reference laboratory FTIR measurements
  • Tested across a wide range of product types and adulteration levels
  • Cost-effective alternative to laboratory-grade FTIR systems

Outcome

  • Immediate on-site alcohol composition results
  • Significantly lower cost per test vs lab method
  • Enables enforcement agencies and manufacturers to screen at scale
  • Applicable to customs checks, market surveillance and production QC
