IndiGo NIR Reflection: Near-Infrared spectrometer for Dark Liquids and Powders

IndiGo NIR Reflection with Cuvette Holder: Near-Infrared Analysis for Powders and Dark Liquids

The IndiGo NIR Reflection with a dedicated cuvette holder is a high-performance analytical configuration engineered to overcome the challenges of complex and opaque matrices. By combining the portable IndiGo NIR core spectrometer, a reflection illumination module (4 broadband NIR LEDs, 700 nm – 1100 nm), and a tailored cuvette support, this system measures diffuse reflectance and backscattering. It stands out as the ideal non-destructive solution for analyzing heterogeneous powders, pastes, suspensions, and dark or highly opaque liquids, right in the field or inside the laboratory.

Key Applications: Mastering Complex and Opaque Sample Analysis

Where traditional transmission setups are blocked by sample opacity, reflectance measurement through a cuvette captures the chemical signature of the material via surface interaction or backscattering:

### 🌾 Agrifood, Grains & Organic Powders

• Flour and Powder Characterization: Instant determination of essential physicochemical parameters (moisture, protein, fat, ash, or starch content) in flours, milk powders, or ground spices.
• Dark Liquids and Roasted Products: Real-time composition and profile monitoring for complex matrices like coffee (whole beans, ground, or opaque liquid extracts) and cocoa.
• Dairy Products and Emulsions: Quantitative testing on thick or opaque samples such as creams, yogurts, and industrial sauces.

### 🛢️ Petrochemicals, Heavy Oils & Industrial Fluids

• Dark Liquids & Used Oil Analysis: Monitoring degradation, water contamination, or soot loading in heavy engine oils, industrial lubricants, and crude oil samples.
• Chemical Formulations & Pastes: Quality and homogeneity control of dark liquid polymers, resins, liquid coatings, paints, or industrial sludges.

### 🧪 Pharmaceuticals & Fine Chemicals

• Raw Material Identification: Rapid non-destructive testing and purity verification of Active Pharmaceutical Ingredients (APIs) or excipients in powder or granulate form before manufacturing.

Comprehensive Software Ecosystem: From Spectral Capture to Chemometrics

The IndiGo NIR Reflection in cuvette mode is powered by our software suite, essential for handling the inherently complex signals of diffuse reflectance:

• SpectroLab (Windows): Comprehensive software included as standard to capture spectra and apply the mathematical scatter corrections crucial for reflectance data (Standard Normal Variate – SNV, Multiplicative Scatter Correction – MSC, or second derivatives to eliminate particle size effects).
• Android Application: Control your spectrometer directly via smartphone or tablet for rapid on-site diagnostics next to storage silos, warehouses, or processing areas.
• « SpectroLink » Python Library: Seamlessly pipe raw reflectance curves into your own **chemometrics** scripts (classification models or PLS regressions) to extract precise quantitative data regardless of light scattering.

Turn Curves into Decisions with the Expert / Capture Suite

Transform your reflectance measurements into an instantaneous field-ready diagnostic tool:

• Expert: Build and refine your calibration models by pairing your captured reflectance spectra with your laboratory reference values (e.g., protein percentage in a specific powder matrix).
• Capture: Deploy those models onto field units. Any operator can then insert a cuvette containing a powder or dark fluid and receive an immediate conformity check or composition readout in seconds.

📦 Delivery & Accessories: Every IndiGo NIR Reflection with cuvette holder is shipped pre-calibrated in wavelength (nanometric scale) and includes its reference reflectance standard. Intensity (radiometric) calibration is available as an option.
