PerkinElmer Spectrum 400 FTIR/NIR Spectrometer (Refurbished)

Overview

The PerkinElmer Spectrum 400 FTIR/NIR Spectrometer is a dual-range, research-grade Fourier Transform spectrometer engineered for high-fidelity molecular characterization across both mid-infrared (MIR) and near-infrared (NIR) spectral domains. Operating on the principle of interferometric signal acquisition via a patented Dynascan™ modified Michelson interferometer, the instrument eliminates mechanical misalignment artifacts—such as mirror tilt and shear—that commonly degrade spectral fidelity in conventional scanning interferometers. Its permanently aligned, hermetically sealed optical bench ensures long-term stability under variable laboratory conditions, resisting humidity ingress and thermal drift without requiring routine optical realignment. The system delivers continuous spectral coverage from 15,000 cm⁻¹ (667 nm) to 350 cm⁻¹ (28.6 µm), enabling simultaneous analysis of overtone and combination bands (NIR) alongside fundamental vibrational modes (MIR) within a single platform. Designed for traceable quantitative analysis, it incorporates PerkinElmer’s Absolute Validation Instrument (AVI) framework—a hardware-embedded reference standard that enables instrument-to-instrument spectral comparability without reliance on external calibration samples.

Key Features

• Dual-band spectral operation: Software-selectable, fully automated switching between MIR and NIR measurement modes—no manual optical component replacement or recalibration required.
• Dynascan™ interferometer architecture: Eliminates dynamic alignment errors through passive optical path stabilization; no active feedback loops or motorized mirror repositioning needed during acquisition.
• Sealed, inert-gas purged optical enclosure: Protects beam splitter, detector, and interferometer optics from ambient moisture and particulate contamination, extending service intervals and ensuring baseline stability over extended duty cycles.
• Automated Vapor Compensation (AVC): Real-time subtraction of atmospheric water vapor and carbon dioxide absorption features using continuously acquired background references—critical for reproducible transmission/absorbance quantitation in non-purged environments.
• AVI-compliant validation suite: Includes factory-installed reference standards and embedded diagnostics for performance verification per ISO 17025-relevant criteria, supporting audit-ready documentation for GLP and GMP workflows.
• Modular detector compatibility: Supports DTGS (MIR) and InGaAs (NIR) detectors with auto-recognized configuration; optional liquid-nitrogen-cooled MCT available for enhanced SNR in demanding applications.

Sample Compatibility & Compliance

The Spectrum 400 accommodates solid, liquid, and gaseous samples via interchangeable accessories including KBr pellet holders, ATR diamond/ZnSe crystals (single-bounce and multi-bounce), gas cells (path lengths 0.1–10 m), and fiber-optic probes for remote or in-line measurements. It complies with ASTM E1421 (Standard Practice for Describing and Measuring Performance of Fourier Transform Mid-Infrared (FT-MIR) Spectrometers) and supports data export formats compatible with ASTM E131 and ISO 11359-2 for polymer characterization. All firmware and control software meet FDA 21 CFR Part 11 requirements for electronic records and signatures when operated with PerkinElmer’s Spectrum Touch™ or Spectrum 10™ software suites (v10.5.1 or later). The refurbished unit undergoes full functional verification against PerkinElmer’s original factory acceptance test (FAT) protocols prior to shipment.

Software & Data Management

Controlled via PerkinElmer Spectrum Touch™ (touch-optimized GUI) or Spectrum 10™ (advanced scripting and macro support), the system provides native support for spectral preprocessing (zero-filling, apodization, phase correction), multivariate analysis (PCA, PLS regression), and library searching (Sadtler, KnowItAll®). Audit trails log all user actions—including parameter changes, background acquisitions, and data exports—with time-stamped, immutable entries. Raw interferograms and processed spectra are stored in vendor-neutral .spa/.spc format, ensuring long-term archival integrity and third-party software interoperability (e.g., MATLAB, Python SciPy, Unscrambler X). Data security is enforced via role-based access controls, encrypted local storage, and optional integration with enterprise LIMS platforms via ODBC or RESTful API.

Applications

• Pharmaceutical QA/QC: Polymorph identification, excipient compatibility screening, and content uniformity testing per USP and ICH Q5A guidelines.
• Materials science: Crosslink density assessment in elastomers, oxidation state mapping in battery cathode materials, and surface functionalization verification on nanomaterials.
• Food & agriculture: Moisture, protein, and fat quantification in grains and dairy products using NIR chemometrics; adulterant detection (e.g., melamine in milk powder) via MIR fingerprint region analysis.
• Environmental monitoring: Speciation of microplastics in aqueous matrices; VOC emission profiling from industrial stacks using gas-phase FTIR with multicomponent spectral fitting.
• Academic research: Time-resolved reaction monitoring (stopped-flow FTIR), catalyst surface intermediate characterization (in situ DRIFTS), and low-temperature matrix isolation spectroscopy.

FAQ

Is this a factory-refurbished unit or third-party refurbished?
This Spectrum 400 has been professionally refurbished by SpectraLab Scientific to OEM-equivalent specifications, including interferometer realignment, detector responsivity calibration, and full spectral validation against NIST-traceable standards.
Does the 6-month warranty cover parts, labor, and on-site service?
Yes—the warranty includes all components, labor, and remote technical support; on-site service is available in North America and Western Europe for an additional fee.
Can the instrument be upgraded to include an integrated ATR accessory or purge gas manifold?
All major accessories—including Pike Technologies GladiATR, Harrick MVP Pro, and PerkinElmer’s Purge Gas Kit—are fully compatible and can be installed post-purchase with minimal downtime.
Are original manuals, software licenses, and certificate of calibration included?
Yes—each unit ships with digital copies of the full manual set, a perpetual license for Spectrum Touch™ software, and a NIST-traceable Certificate of Calibration valid at time of dispatch.
What is the typical lead time for delivery and installation?
Units are drawn from active inventory; standard delivery is 5–7 business days after order confirmation, with optional pre-installation remote setup assistance provided at no cost.
