TuoPu FTIR 930 Fourier Transform Infrared Spectrometer

Overview

The TuoPu FTIR 930 is a compact, portable Fourier Transform Infrared (FTIR) spectrometer engineered for reliable mid-infrared spectral acquisition in diverse laboratory, field, and quality control environments. Based on Michelson interferometry, the instrument employs a high-stability optical bench with a permanently aligned interferometer, a broadband KBr-beam splitter, and a deuterated triglycine sulfate (DTGS) detector optimized for ambient-temperature operation. Its design prioritizes mechanical robustness and thermal stability to maintain consistent wavenumber accuracy (< ±0.05 cm⁻¹) and photometric repeatability across extended measurement sessions. The FTIR 930 operates within the standard mid-IR range of 7800–375 cm⁻¹—covering fundamental vibrational modes of organic functional groups (e.g., C=O stretch at ~1700 cm⁻¹, O–H broad band at 3600–3200 cm⁻¹, C–H aliphatic at ~2960 cm⁻¹) and enabling identification, quantification, and structural analysis of polymers, pharmaceuticals, coatings, and contaminants.

Key Features

• Portable form factor with integrated battery option and shock-absorbing housing, suitable for on-site material verification and mobile lab deployment.
• Fixed 1.0 cm⁻¹ nominal resolution, configurable via zero-filling and apodization functions to support both rapid screening and higher-resolution spectral interrogation.
• Optimized optical path with sealed, purged interferometer compartment to minimize atmospheric CO₂ and H₂O vapor interference—critical for reproducible baseline stability in non-purged environments.
• High-sensitivity DTGS detector delivering a measured signal-to-noise ratio of ≥15,000:1 (at 4 cm⁻¹ resolution, 1 min scan, 2100–2000 cm⁻¹ region), ensuring detection of trace components and low-concentration analytes.
• Plug-and-play USB 2.0 interface compatible with Windows-based acquisition software; no external power supply required during field use when operating on internal rechargeable battery.
• Pre-aligned, maintenance-free optics with no moving mirrors or realignment procedures—reducing operator dependency and long-term calibration drift.

Sample Compatibility & Compliance

The FTIR 930 supports standard transmission, attenuated total reflectance (ATR), and diffuse reflectance sampling configurations via interchangeable accessories (sold separately). ATR modules with diamond, ZnSe, or Ge crystals enable direct analysis of solids, pastes, and liquids without sample preparation. Transmission cells (KBr, CaF₂) accommodate solutions and thin films. All measurement protocols comply with ASTM E1421–22 (Standard Guide for Describing and Measuring Performance of FTIR Spectrometers) and ISO 18387:2015 (Molecular spectroscopy — Requirements for FTIR instrumentation). Data acquisition workflows are structured to support GLP and GMP documentation requirements, including user-defined metadata tagging, electronic signature fields, and audit-trail-capable file export (CSV, JCAMP-DX, .SPA).

Software & Data Management

The bundled TuoPu IRSoft™ suite provides full instrument control, real-time interferogram monitoring, spectral processing (baseline correction, normalization, peak integration, derivative calculation), and library search against built-in reference databases (including >10,000 organic compounds per NIST 2020 IR Library). Spectra are stored in vendor-neutral formats compliant with ASTM E131 and IUPAC recommendations. Export options include PDF reports with embedded spectra, annotated peaks, and measurement parameters. For regulated environments, optional 21 CFR Part 11-compliant modules provide role-based access control, electronic signatures, and immutable audit logs—fully traceable from raw interferogram to final report.

Applications

• Raw material identity testing in pharmaceutical manufacturing (USP and EP 2.2.24 compliant).
• Failure analysis of polymer degradation, additive migration, or contamination in packaging and medical devices.
• Forensic analysis of paints, adhesives, fibers, and illicit substances.
• Quality assurance of lubricants, fuels, and industrial solvents via functional group fingerprinting.
• Educational use in undergraduate chemistry and materials science laboratories for spectral interpretation and quantitative calibration exercises.
• Environmental field screening of soil extracts or waterborne organics using portable ATR sampling.

FAQ

Is the FTIR 930 suitable for quantitative analysis?
Yes—when used with validated calibration models and appropriate referencing (e.g., internal standards or multivariate regression), it supports quantitative determination of active pharmaceutical ingredients (APIs), polymer blend ratios, and contaminant concentrations.
Does the instrument require external purge gas?
No. The sealed, desiccated interferometer compartment eliminates the need for continuous dry air or nitrogen purge, though optional purge ports are available for ultra-high-stability applications.
Can the FTIR 930 be integrated into automated production lines?
Yes—via RS-232 or TCP/IP API support, the instrument accepts remote command sequences for unattended batch measurements and triggers external peripherals such as auto-samplers or robotic arms.
What spectral libraries are included by default?
The base package includes the NIST 2020 IR Library, Polymer Additives Database, and USP Reference Standards Library—with license-enabled expansion to commercial libraries (e.g., Sadtler, Bio-Rad KnowItAll).
How often does the instrument require wavelength calibration verification?
Factory-calibrated polystyrene film validation is recommended quarterly; annual recalibration by an ISO/IEC 17025-accredited service provider is advised for GxP-regulated use.
