Thermo Scientific Nicolet iS10 Fourier Transform Infrared (FT-IR) Spectrometer

Overview

The Thermo Scientific Nicolet iS10 Fourier Transform Infrared (FT-IR) Spectrometer is an engineered analytical platform designed for robust, reproducible molecular identification and quantitative analysis in regulated and non-regulated laboratory environments. Based on Michelson interferometry with dynamic alignment correction, the instrument delivers high-fidelity mid-infrared spectra (typically 4000–400 cm⁻¹) with consistent wavenumber accuracy and photometric linearity. Its sealed, desiccated optical bench—housing a permanently aligned, diamond-turned interferometer and broadband beam splitter—minimizes drift from humidity or solvent vapor exposure, ensuring long-term spectral fidelity without routine optical realignment. The system integrates hardware-based performance verification with software-driven validation protocols, enabling laboratories to meet stringent quality assurance requirements across pharmaceutical, polymer, chemical, and forensic applications.

Key Features

• Self-compensating, dynamically aligned interferometer with real-time optimization of optical throughput and scan speed (up to 16 scans/sec)
• Sealed, dry optics enclosure with integrated humidity sensor and user-replaceable desiccant cartridge
• Two detector options: room-temperature deuterated triglycine sulfate (DTGS) for general-purpose analysis; liquid nitrogen-cooled mercury cadmium telluride (MCT) for high-sensitivity, rapid-scan applications
• Dual-source configuration: Ever-Glo™ mid-IR source (user-accessible from sample compartment) and tungsten-halogen visible/NIR source
• KBr/Ge and extended-range XT-KBr/Ge beam splitters optimized for mid-IR spectral coverage and signal-to-noise performance
• Smart Accessory™ recognition technology enabling automatic parameter loading and calibration transfer when attaching Thermo Scientific Smart iTR™ ATR, transmission cells, or gas cells
• Five-year warranty on diamond crystal in Smart iTR™ ATR accessory—specifically engineered for optimal coupling with the iS10 optical design

Sample Compatibility & Compliance

The Nicolet iS10 supports diverse sampling modalities including transmission, attenuated total reflectance (ATR), diffuse reflectance (DRIFTS), and specular reflection. It is fully compatible with automated accessories such as powder and liquid autosamplers, microtiter plate readers, and external modules including the Nicolet iZ10 FT-IR interface for TGA-IR coupling or NIR extension (InGaAs detector). Regulatory compliance is embedded at the system level: SPV (System Performance Verification) software implements ASTM E1421 using NIST-traceable polystyrene film (NG-11 standard) housed in a motorized wheel. ValPro™ qualification packages provide documented Design Qualification (DQ), Installation Qualification (IQ), and Operational Qualification (OQ) evidence aligned with ISO/IEC 17025, GMP, and GLP frameworks. Electronic signatures, audit trails, and role-based access control are enabled via the OMNIC Security Suite compliant with FDA 21 CFR Part 11.

Software & Data Management

Controlled by OMNIC Specta™ software, the iS10 offers a unified interface for acquisition, processing, library searching, and reporting. The OMNIC Spectral Library contains over 9,000 reference spectra with hierarchical search algorithms—including single-component identification, multi-component deconvolution, and mixture ranking—enabling confident characterization of unknowns and complex formulations. TQ Analyst Professional adds multivariate calibration tools (PLS, PCR, discriminant analysis) for quantitative prediction of composition or purity. OMNIC Series modules support time-resolved kinetics, TGA-IR synchronization, and high-speed scanning. Automated array analysis supports microplate and well-based workflows. All data files include embedded metadata (instrument parameters, operator ID, timestamp, calibration history), and raw interferograms are retained for reprocessing—ensuring full traceability and method revalidation capability.

Applications

The Nicolet iS10 serves as a primary tool for material identity testing in pharmaceutical QC (per USP and EP 2.2.24), polymer grade verification, contaminant identification in electronics manufacturing, forensic fiber analysis, and raw material release testing. Its rapid ATR-based screening capability enables direct analysis of solids, gels, and viscous liquids without KBr pellet preparation. Coupled with the iZ10 module, it extends functionality to hyphenated techniques such as TGA-FTIR for thermal degradation profiling or NIR-FTIR for bulk blend uniformity assessment. In R&D settings, its SOP-driven operation supports method transfer between sites, while its spectral reproducibility underpins stability-indicating assay development.

FAQ

What regulatory standards does the Nicolet iS10 support for GxP environments?
It supports ASTM E1421 for instrument performance verification, NIST-traceable calibration, and full 21 CFR Part 11 compliance via OMNIC Security Suite—including electronic signatures, audit trails, and user access controls.
Can the iS10 be integrated with thermal analysis instruments?
Yes—via the optional Nicolet iZ10 FT-IR module, which provides dedicated optical coupling for TGA-IR interfaces and supports both DTGS and MCT detection for synchronized thermal-spectral analysis.
Is hardware maintenance required for optical alignment?
No—the interferometer features dynamic self-alignment and diamond-turned optics; no manual collimation or periodic realignment is necessary during normal operation.
How is moisture protection implemented in the optical system?
The optical bench is hermetically sealed and continuously monitored by an internal humidity sensor; desiccant is user-replaceable without disassembly, and the entire assembly is chemically resistant to common lab solvents.
Does the system support automated high-throughput workflows?
Yes—through compatibility with liquid/powder autosamplers, microtiter plate adapters, and OMNIC’s AutoArray module for batch spectral acquisition and comparative analysis.
