PerkinElmer Spectrum Two FTIR Spectrometer

Overview

The PerkinElmer Spectrum Two FTIR Spectrometer is a compact, robust benchtop Fourier Transform Infrared (FTIR) spectrometer engineered for routine qualitative and quantitative analysis across academic, industrial, and regulatory laboratory environments. Built upon Michelson interferometer architecture with a permanently aligned optical path and dynamically aligned moving mirror mechanism, the system delivers high spectral fidelity through precise phase correction and rapid data acquisition. Its core measurement principle relies on interferometric modulation of broadband IR radiation—generated by a silicon carbide globar source—followed by Fourier transformation of the resulting interferogram to yield absorbance or transmittance spectra in wavenumber space (cm⁻¹). Designed for operational simplicity without compromising analytical rigor, the Spectrum Two integrates a thermoelectrically cooled deuterated triglycine sulfate (DTGS) detector as standard, ensuring stable baseline performance and low drift over extended acquisition periods.

Key Features

• Fully integrated universal sampling platform supporting ATR (Attenuated Total Reflectance), transmission, reflectance, and gas cell configurations—no tool changes or realignment required between techniques.
• Compact footprint (34 × 30 × 20 cm) with shock-absorbing chassis and sealed optics enclosure, enabling deployment in shared labs, QA/QC cleanrooms, or mobile analytical units.
• Onboard touchscreen interface with pre-optimized method templates for polymers, pharmaceuticals, contaminants, and forensic samples—reducing operator training time and method development overhead.
• Automated purge management system compatible with dry air or nitrogen supply, minimizing atmospheric water vapor and CO₂ interference during high-sensitivity measurements.
• Ruggedized design compliant with IEC 61010-1 safety standards and CE/UKCA marking for electromagnetic compatibility and electrical safety.

Sample Compatibility & Compliance

The Spectrum Two accommodates solid, liquid, paste, and gaseous samples via interchangeable accessories—including diamond-crystal ATR accessories (single-bounce and multi-bounce), KBr pellet press kits, and 10-cm pathlength gas cells with CaF₂ windows. It supports compliance workflows aligned with ASTM E1421 (Standard Practice for Describing and Measuring Performance of FTIR Spectrometers), ISO 18387 (Vibrational spectroscopy — Vocabulary), and USP (Infrared Absorption Spectrophotometry). Data integrity features include user-level access control, electronic signatures, and audit-trail-enabled instrument logs—facilitating alignment with FDA 21 CFR Part 11 requirements when used with optional Spectrum Touch™ software and networked LIMS integration.

Software & Data Management

Controlled by Spectrum Touch™ software (Windows-based), the system provides intuitive workflow navigation, real-time spectral preview, automated peak identification using reference libraries (e.g., Sadtler, Polymer, Forensic), and customizable report generation with embedded metadata (operator ID, date/time stamp, instrument serial number, acquisition parameters). All spectral data are stored in standardized JCAMP-DX format, ensuring long-term archival compatibility and third-party software interoperability (e.g., OMNIC, GRAMS/AI, MATLAB). Optional Spectrum Quant™ module enables calibration curve construction, multivariate regression (PLS), and statistical process control (SPC) charting for release testing and stability studies under GLP/GMP conditions.

Applications

• Pharmaceutical raw material identification and excipient verification per ICH Q5C and USP monographs.
• Failure analysis of polymer components—including oxidation state assessment, additive migration, and degradation product detection.
• Contaminant identification in electronics manufacturing (e.g., flux residues, silicone oils, fingerprint organics).
• Quality assurance of coatings, adhesives, and composite laminates in aerospace and automotive supply chains.
• Educational instruction in molecular spectroscopy, vibrational mode assignment, and chemometric modeling at undergraduate and graduate levels.

FAQ

What sample preparation methods are supported without accessory changes?
ATR, transmission, and diffuse reflectance measurements can be performed interchangeably using the integrated universal sampling stage—no optical realignment or hardware swapping is required.
Is the Spectrum Two compliant with 21 CFR Part 11 for regulated environments?
Yes—when deployed with Spectrum Touch™ software configured for role-based authentication, electronic signatures, and full audit trail logging, it meets foundational requirements for electronic records and signatures in FDA-regulated laboratories.
Can the instrument be operated remotely or integrated into a lab automation system?
It supports Ethernet and USB connectivity; remote operation is enabled via PerkinElmer’s Spectrum Connect™ API for integration with LIMS, MES, or robotic sample handlers.
What maintenance is required to sustain spectral accuracy over time?
Annual verification using NIST-traceable polystyrene film standards is recommended; optical alignment remains stable due to the permanently aligned interferometer design—no user-serviceable mirrors or alignment screws are present.
Does the system support hyphenated techniques such as FTIR-GC or FTIR-TGA?
While not natively coupled, the Spectrum Two accepts analog voltage inputs from external thermal analyzers or gas chromatographs for synchronized spectral acquisition—enabling post-acquisition correlation of IR features with mass or thermal events.
