Bruker Invenio Fourier Transform Infrared Spectrometer (FTIR) and Bruker Hyperion II FT-IR Microscope

M26-016

The 76 MXSG is requesting Bruker Invenio Fourier Transform Infrared Spectrometer (FTIR) and Bruker Hyperion II FT-IR Microscope. This requirement must have the following specifications:

Bruker Invenio Fourier Transform Infrared Spectrometer (FTIR) – Quantity: 1

• Benchtop FT-IR system with 20-meter fixed path-length gas cell optimized for quantitative gaseous analysis.

• Integrated laser system for precise gas cell alignment and path length verification (±0.1 m accuracy).

• High-sensitivity Deuterated Triglycine Sulfate (DTGS) detector.

• Spectral resolution of 0.4 cm⁻¹ or better; specify signal-to-noise ratio per ASTM E1421.

• Mid-infrared KBr beamsplitter covering 8,000–300 cm⁻¹ standard range; optional extended range

11,000–350 cm⁻¹ available at additional cost.

• Permanently aligned interferometer with documented alignment stability and lifespan.

• Electronically stabilized infrared source with specified stability and lifetime.

• Wavenumber accuracy of 0.01 cm⁻¹ or better at 2000 cm⁻¹, verified by standard method (e.g., polystyrene film).

Fixed Path-Length Gas Cell:

• Aluminum body coated with corrosion-resistant material; chemical resistance details required.

• Operates up to 3 ATM with calibrated pressure gauge and overpressure relief valve.

• Easily accessible mirrors with specified reflectivity and included realignment tools.

• Heated with precise temperature control, capable of reaching ≥100°C.

User Manual:

• Comprehensive electronic (PDF) and printed manuals including safety notices, operating instructions, maintenance schedules, software operation, calibration procedures, troubleshooting, and technical support contacts.

Analytical Software:

• Latest manufacturer’s version with full instrument control.

• Automatic compensation for water vapor and CO₂ interference without separate reference spectrum; specify algorithm.

• Supports robust quantitative gas analysis methods compatible with existing spectral libraries;

detail algorithms (e.g., CLS, PLS).

• Displays sample metadata alongside spectra (8000–300 cm⁻¹).

• Allows simultaneous data acquisition and post-processing.

• Includes standard spectral processing functions (normalization, subtraction, overlay, baseline correction, quantitative analysis).

• Compatible with Microsoft Windows 11 and includes Microsoft Office Small Business Edition or equivalent.

• Peak find capability for easy spectral peak identification.

Computer Hardware:

• Dedicated computer and monitor meeting or exceeding manufacturer’s recommended specifications; specify minimum requirements (processor, RAM, storage, graphics, display resolution).

Supplies and Special Tools:

• All unique supplies for operation plus 60-day consumables supply (e.g., desiccant, cleaning materials).

• Special tools for routine maintenance and gas cell alignment are included with detailed list.

On-Site Installation, Verification, and Training:

• One (1) day set-up and One (1) day training minimum 8 hours on-site installation and performance verification by qualified service engineer, including testing of resolution, wavenumber accuracy, and signal-to-noise ratio.

• Additional 8 hours training for Air Force chemists covering basic operation, custom quantitative method development, and programming.

• Documentation of installation and verification procedures provided.

Bruker Hyperion II FT-IR Microscope – Quantity: 1
