PIKE 16xx-xxxx Infrared Spectroscopy Accessories Kit

Overview

The PIKE 16xx-xxxx Infrared Spectroscopy Accessories Kit is a modular, application-optimized suite of sampling interfaces engineered for integration with Fourier Transform Infrared (FTIR) spectrometers. Designed and manufactured in the United States, this kit enables precise, reproducible spectral acquisition across all major IR sampling modalities—including transmission, Attenuated Total Reflectance (ATR), specular reflection, and diffuse reflectance—under rigorously controlled thermal and environmental conditions. Its architecture supports fundamental spectroscopic measurements compliant with ASTM E1421, ISO 18387, and USP , facilitating quantitative and qualitative analysis of molecular functional groups in research, quality control, and regulatory environments.

Key Features

• Multi-modal sampling capability: Seamless transition between transmission, ATR, specular reflection, and diffuse reflectance configurations without realignment or recalibration.
• Thermally robust design: Compatible with temperature-controlled stages spanning –80 °C to +500 °C, enabling kinetic studies, phase transition analysis, and high-temperature decomposition profiling.
• Gas-phase optimization: Includes long-path gas cells (up to 16 m optical path length) with heated/coolable housings, pressure-rated windows (CaF₂, BaF₂, or KBr), and purge-compatible manifolds for trace gas detection and reaction monitoring.
• ATR versatility: Fixed-angle (45° and 60°) and variable-angle ATR accessories featuring single-bounce diamond, ZnSe, or Ge crystals; validated for powders, viscous liquids, thin films (<100 nm), and macro-sized solids (up to 100 mm diameter).
• Liquid transmission flexibility: Supports both fixed-path (10–100 µm) and continuously adjustable pathlength cells (0.1–10 mm), with chemically resistant flow cells for aqueous and non-aqueous solvents—including D₂O, DMF, and ionic liquids.
• Mechanical interoperability: All accessories conform to standard FTIR beam geometry (e.g., 25 mm collimated beam, 15° incidence angle tolerance) and mount via PIKE’s universal kinematic interface for repeatable positioning within ±2 µrad angular error.

Sample Compatibility & Compliance

The 16xx-xxxx kit accommodates organic, inorganic, polymeric, and biological samples in solid, liquid, and gaseous states. Solid samples include pressed pellets (KBr, CsI), mulls, thin films on reflective substrates, and bulk materials (metals, ceramics, composites). Liquid compatibility extends to corrosive media (e.g., concentrated acids, halogenated solvents) when using appropriate cell materials and gasketing. Gas-phase analysis meets requirements for EPA Method TO-14A and ISO 14687-2. All accessories are constructed from vacuum-compatible, low-outgassing materials (316 stainless steel, anodized aluminum, fused silica) and support GLP/GMP-compliant workflows through traceable calibration documentation and mechanical serial-number registration.

Software & Data Management

Each accessory is fully supported by PIKE’s SpectraManager™ v3.x software suite, which provides automated configuration recognition, thermal ramp scripting, real-time spectral subtraction (e.g., background correction during in-situ heating), and ATR correction algorithms per ASTM E2756. Data export conforms to JCAMP-DX v6.00 and HDF5 standards. Audit trails, user access controls, and electronic signatures comply with FDA 21 CFR Part 11 requirements when deployed with validated LIMS or ELN integrations.

Applications

• In-situ catalysis studies under reactive gas atmospheres (CO, NH₃, H₂O vapor) at elevated temperatures.
• Hydration/dehydration kinetics of pharmaceutical hydrates monitored via variable-temperature ATR-FTIR.
• Surface oxidation behavior of battery electrode materials using grazing-angle reflection FTIR.
• Quantitative analysis of residual solvents in polymer films via high-sensitivity transmission measurement.
• Microplastic identification in environmental water samples using focal-plane array (FPA) mapping coupled with transmission microcells.
• Structural characterization of metal–organic frameworks (MOFs) under controlled humidity and CO₂ exposure.

FAQ

Is the 16xx-xxxx kit compatible with non-PIKE FTIR systems?
Yes—mechanical and optical specifications align with industry-standard FTIR beam geometry (e.g., Thermo Nicolet iS50, Bruker Vertex 80v, PerkinElmer Frontier). Adapter plates and alignment tools are included.
Can the ATR accessories be used for quantitative analysis?
Yes—when paired with certified reference standards and calibrated using NIST-traceable polystyrene film, the system achieves ≤±2% relative standard deviation in peak area reproducibility across 50 consecutive measurements.
Does the kit include thermal calibration certificates?
Each temperature-controlled accessory ships with a NIST-traceable calibration certificate covering the full operational range (–80 °C to +500 °C), including uncertainty budgets per ISO/IEC 17025.
Are custom pathlengths or window materials available?
Yes—PIKE offers engineering customization including CaF₂ windows for UV-Vis-IR extension, sapphire windows for high-pressure gas cells (>200 bar), and microfluidic transmission cells with integrated Peltier control.
What maintenance protocols are recommended?
Routine cleaning follows ASTM E1421 Annex A3 guidelines; crystal surfaces require ethanol/isopropanol wipe-down with lint-free wipes; optical alignment verification is recommended every 200 hours of operation or after mechanical shock events.
