IndiGo NIR Transmission: Near-Infrared spectrometer for Liquids and Fluids

IndiGo NIR Transmission: Near-Infrared Spectrometry for Liquids and Fluids

The IndiGo NIR Transmission is a compact and high-performance spectral analysis system specifically engineered for the non-destructive characterization of translucent liquids and homogeneous fluids. By combining the portable IndiGo NIR core spectrometer with an optimized cuvette-holder transmission module, this setup delivers laboratory-grade accuracy for absorption and transmission spectra. It offers an ideal, cost-effective solution for rapid quality control in the field, on the factory floor, or inside the lab.

Key Applications: Real-Time Quantitative and Qualitative Fluid Analysis

By measuring light transmission directly through a standard optical cuvette, the IndiGo NIR Transmission allows you to instantly identify chemical components and quantify concentrations inside fluids without complex sample preparation:

### 🐟 Agrifood & Oil Analysis (Lipids)

• Fatty Acid Profiling: Rapid analysis of vegetable and animal oils (for instance, characterizing fish oil quality and accurately measuring omega-3 and omega-6 concentrations).
• Edible Oil Quality Control: Monitoring aging processes, rancidity, or detecting adulteration (fraud) in high-value oils such as extra virgin olive oil.
• Beverages & Syrups Testing: Real-time sugar content measurement (Brix checking) and characterization of clear aqueous solutions.

### 💧 Water Quality & Environmental Monitoring

• Industrial Wastewater Screening: Fast screening of organic pollutants, hydrocarbon traces, or specific chemical contaminants in process water and translucent industrial effluents before discharge.
• Nutrient Testing: Real-time concentration monitoring of liquid nutrient solutions in hydroponics and precision agriculture.

### 🛢️ Petrochemicals, Biofuels & Fine Chemicals

• Fuel Characterization: Rapid compliance testing of gasoline, diesel, and tracking purity or blending ratios in biofuels (bioethanol, biodiesel).
• Chemical Reaction Monitoring: Real-time tracking of polymerization processes or liquid formulations by measuring the evolution of specific absorption bands (C-H and O-H overtones).

Comprehensive Software Ecosystem: From Spectral Capture to Chemometrics

The IndiGo NIR Transmission is driven by an intuitive and highly functional software suite, tailored to handle advanced data processing:

• SpectroLab (Windows): Comprehensive software included as standard to capture transmission spectra, apply essential mathematical processing (blank/reference subtraction, smoothing), and export raw data.
• Android Application: Available on the PlayStore, giving operators full mobility to control cuvette measurements directly from a smartphone or tablet in the field.
• « SpectroLink » Python Library: Seamlessly interface your IndiGo NIR unit with your own custom **chemometrics** scripts (such as PLS or PCR regression models). It is the perfect tool to transform raw absorbance curves into precise, actionable concentration values (e.g., omega-3 content in g/100g).

Turn Raw Curves into Predictions with the Expert / Capture Suite

Harness the true power of chemometrics to transform your transmission spectra into immediate quantitative insights:

• Expert: Use your known reference standards to build, calibrate, and validate mathematical prediction models (calibration curves).
• Capture: Deploy those pre-built models onto field units. Any operator can then scan an unknown liquid sample and get instant concentration results or conformity diagnostics displayed right on screen.

📦 Delivery & Accessories: Every IndiGo NIR Transmission is shipped pre-calibrated in wavelength (nanometric scale) alongside its dedicated cuvette-holder module. Intensity (radiometric) calibration is available as an option.
