Ocean Optics Flame-NIR+ Portable Near-Infrared Spectrometer

Overview

The Ocean Optics Flame-NIR+ is a compact, USB-powered portable near-infrared spectrometer engineered for field-deployable and benchtop quantitative and qualitative analysis in regulated and non-regulated environments. Based on a fixed-grating optical design with an uncooled InGaAs linear detector array, it operates across the critical 970–1700 nm spectral window—covering the first overtone region of C–H, O–H, and N–H bonds essential for organic compound identification and quantification. Its grating-scanning architecture enables stable, repeatable spectral acquisition without moving parts beyond the internal scanning mechanism, ensuring mechanical robustness suitable for mobile QC labs, production line monitoring, and agricultural or pharmaceutical field applications. The device delivers high photometric fidelity with a full-signal SNR of 6000:1 and dynamic range exceeding 6000:1 per single acquisition—enabling reliable detection of low-concentration analytes in complex matrices such as powders, tablets, slurries, and biological tissues.

Key Features

• Compact & Rugged Form Factor: Measuring only 89.1 × 63.3 × 31.9 mm and weighing 265 g, the Flame-NIR+ is optimized for handheld operation and integration into automated sampling stations or portable analytical kits.
• Thermally Stable Optical Design: Engineered with low thermal drift (0.08 nm/°C), the spectrometer maintains wavelength calibration integrity across ambient temperature fluctuations typical in non-climate-controlled environments—reducing need for frequent recalibration.
• High-Speed Acquisition: Capable of up to ~400 spectra per second, supporting real-time process monitoring and rapid sample screening protocols compliant with ASTM E1655 and ISO 12099 standards for NIR method validation.
• Flexible Integration: Equipped with a standard Micro-USB interface for direct connection to Windows, Linux, or macOS hosts; compatible with Ocean Insight’s OceanView software suite and third-party platforms via SDK (C/C++, Python, LabVIEW).
• Modular Sampling Compatibility: Designed for seamless coupling with fiber-optic probes, integrating spheres, transmission cells, and contact reflectance accessories—supporting ASTM E2739-compliant reflectance, transmittance, and diffuse reflectance measurements.
• Low-Power Operation: Draws <500 mW from USB bus power, enabling extended battery-powered use when paired with portable power banks or industrial-grade USB hubs.

Sample Compatibility & Compliance

The Flame-NIR+ supports solid, semi-solid, and liquid samples across diverse industrial sectors—including pharmaceutical tablet assay and blend uniformity testing (per USP <1119>), grain moisture and protein analysis (AOAC 988.12), dairy fat/protein quantification (ISO 15104), and botanical extract fingerprinting. Its optical path accommodates standard 400–600 µm core fibers and integrates with GLP/GMP-aligned accessories featuring serialized traceability. While the instrument itself does not include built-in CFR Part 11 compliance features, its data output format (ASCII .csv, .jdx) and API-driven control support audit-trail-enabled software architectures required for regulated QC workflows.

Software & Data Management

Ocean Insight provides the OceanView spectroscopy platform (v2.x), offering real-time spectral visualization, baseline correction, Savitzky-Golay smoothing, and peak integration tools. For chemometric modeling, raw spectra export seamlessly to industry-standard packages including MATLAB, Unscrambler X, and Pirouette. The included SDK enables custom application development for automated pass/fail decision logic, multivariate calibration deployment (PLS, PCA), and integration with LIMS or MES systems. All spectral metadata—including integration time, scan average count, and detector temperature—is embedded in exported files to satisfy ALCOA+ data integrity principles.

Applications

• Pharmaceutical: Raw material ID (Raman/NIR hybrid workflows), tablet coating thickness estimation, excipient compatibility screening
• Food & Agriculture: Moisture, starch, and oil content in cereals and nuts; authenticity verification of olive oil and honey
• Chemicals: Polymer composition analysis (e.g., polyethylene branching ratio), solvent concentration in reaction mixtures
• Environmental: Soil organic carbon and nitrogen mapping; microplastic spectral library matching
• Biotechnology: Cell culture density estimation, protein concentration in clarified lysates

FAQ

Is the Flame-NIR+ suitable for GMP-regulated environments?

Yes—when deployed with validated chemometric models and controlled software configurations (e.g., locked OceanView settings, version-controlled calibration files), it meets foundational requirements for Stage 1–2 process analytical technology (PAT) implementation per FDA Guidance for Industry.
Can I perform quantitative calibrations directly on the device?

No—the Flame-NIR+ is a data acquisition engine only. Quantitative models must be developed externally using reference methods and deployed via host software or embedded inference engines.
What is the recommended calibration frequency?

Wavelength calibration is factory-set and stable; intensity calibration using a NIST-traceable tungsten-halogen or ceramic source is advised before each analytical session or after ambient temperature shifts >5°C.
Does it support fiber-optic probe interchangeability?

Yes—compatible with SMA 905 connectors and all Ocean Insight’s NIR-optimized probes, including bifurcated reflection probes and immersion transmission cells.
Is firmware upgrade supported in the field?

Yes—via OceanView or command-line utilities; all firmware revisions are digitally signed and documented in Ocean Insight’s public release notes archive.
