Overview
The JASCO FI/IR NRS Series represents an integrated platform of Fourier Transform Infrared (FTIR) and Raman spectroscopy systems engineered for high-fidelity vibrational spectral analysis. Built upon core principles of interferometry (for FTIR) and inelastic light scattering (for Raman), the NRS series delivers simultaneous or complementary molecular fingerprinting across organic, inorganic, polymeric, and pharmaceutical samples. The FI/IR-4000R and FI/IR-6000R models incorporate a maintenance-free optical design with a permanently aligned Michelson-type interferometer featuring a cube-corner retroreflector—ensuring long-term alignment stability and minimizing drift-induced artifacts. The NRS-5000/7000 Raman modules integrate confocal laser excitation (typically 532 nm or 785 nm), high-throughput spectrographs, and thermoelectrically cooled CCD detectors to support micro-sampling down to ~1 µm spatial resolution. All systems operate under vacuum or purged environments to suppress atmospheric CO₂ and H₂O absorption bands, enabling baseline integrity in the mid-IR (4000–400 cm⁻¹) and Raman shift ranges (50–4000 cm⁻¹).
Key Features
- High-stability interferometer with 24-bit low-noise analog-to-digital conversion and digital signal processing (DSP)-controlled mirror drive for sub-nanometer positional accuracy
- FI/IR-6000R achieves spectral resolution ≤ 0.07 cm⁻¹ with signal-to-noise ratio ≥ 55,000:1 (at 4 cm⁻¹ resolution, 1 min scan, 4000 cm⁻¹)
- NRS-5000/7000 supports automated laser power optimization, real-time focus tracking, and hardware-synchronized step-scan acquisition
- Integrated software-controlled auto-alignment and intensity calibration routines reduce operator dependency and improve inter-laboratory reproducibility
- Large-volume sample compartment accommodates accessories including ATR, transmission cells, gas cells, and cryogenic stages
- Modular architecture enables seamless coupling with microscopy (IR/Raman mapping), thermal analyzers (TGA-FTIR), and chromatographic interfaces (GC-FTIR)
Sample Compatibility & Compliance
The FI/IR NRS platform accepts solid, liquid, gel, and thin-film specimens without mandatory derivatization. Micro-sampling is supported via motorized XYZ stages and objective-based focusing (20× to 100× magnification), enabling analysis of heterogeneous surfaces, cross-sections, and inclusion particles. All instruments comply with ISO 17025 requirements for analytical laboratory competence and support audit-ready data integrity features—including electronic signatures, user access control, and immutable audit trails—as required by FDA 21 CFR Part 11 and EU Annex 11. Routine performance qualification (PQ) protocols align with ASTM E1421 (Standard Practice for Describing and Measuring Performance of FTIR Spectrometers) and USP (Infrared Absorption Spectrophotometry).
Software & Data Management
Spectra Manager™ C software provides unified control for both FTIR and Raman modules, supporting method-driven workflows, spectral library search (including commercial and custom databases), and multivariate analysis (PCA, PLS). Raw interferograms and spectra are stored in vendor-neutral JCAMP-DX format. The system includes automatic wavenumber and intensity correction algorithms—compensating for laser line shifts, detector nonlinearity, and grating efficiency variations across the spectral range. Batch processing, report generation (PDF/HTML), and LIMS integration via ASTM E1714-compliant APIs ensure compatibility with enterprise-scale quality management systems. Audit trail logs record all parameter changes, spectrum acquisitions, and post-processing steps with timestamp, user ID, and IP address metadata.

FAQ
Does the FI/IR NRS series support GLP/GMP-compliant operation?
Yes—the system includes configurable user roles, electronic signatures, full audit trail logging, and 21 CFR Part 11–compliant data archiving options.
Can the same sample stage be used for both FTIR and Raman measurements?
Yes—NRS-5000/7000 models feature shared XYZ positioning and autofocus logic, enabling correlative IR/Raman microspectroscopy on identical coordinates.
What is the minimum detectable sample area for micro-Raman analysis?
With a 100× objective and diffraction-limited excitation, lateral resolution is approximately 0.5 µm; effective sampling area depends on laser spot size and integration time.
Is vacuum purging mandatory for high-resolution FTIR measurements?
Vacuum or dry-air purging is strongly recommended for resolutions ≤ 0.25 cm⁻¹ to eliminate rotational-vibrational water and CO₂ interference in the 2400–2200 cm⁻¹ and 1900–1300 cm⁻¹ regions.
How does the system handle spectral calibration drift during extended acquisition?
Real-time HeNe laser referencing and periodic internal standard checks (e.g., polystyrene film) enable automatic wavenumber recalibration at user-defined intervals.
