Fourier Transform Infrared Spectrophotometer IRXross

Importance of the Topic

Fourier transform infrared (FTIR) spectroscopy remains a cornerstone in analytical chemistry, offering non-destructive molecular fingerprinting across diverse fields from environmental monitoring to industrial quality control. The evolution of FTIR instrumentation towards higher sensitivity, automation, and regulatory compliance is critical to meet increasing demands for trace analysis, rapid reaction monitoring, and contaminant identification.

Objectives and Study Overview

This document introduces the IRXross™ FTIR spectrophotometer platform, designed to combine high-end sensitivity with built-in analytical intelligence and full compliance with industry regulations. Key objectives include demonstrating ultra-low noise performance, ultra-high sensitivity, high-resolution and high-speed measurement capabilities, and seamless data management workflows.

Methodology and Instrumentation

The study leverages advanced FTIR methodologies:

• Mid-level IRXross interferometer achieving 55,000:1 signal-to-noise ratio (1-minute integration).
• Single-reflection ATR attachments (QATR™10, MIRacle™10) with various prism materials (diamond, ZnSe, Ge) for liquids, polymers, and surface films.
• High-resolution (0.25 cm⁻¹) and high-speed (up to 20 spectra/s) measurements using DL ATGS and optional T2SL detectors.
• Gas analysis with configurable gas cells (path lengths from 5 cm to ≥10 m) and N₂O greenhouse gas detection at 500 ppm.
• Automated workflows using IR Pilot™, contaminant and identification programs, and EDXIR-Analysis™ for integrated EDX-FTIR contaminant screening.
• Data management with LabSolutions IR, DB IR and CS IR software suites for ER/ES compliance, audit trails, and project management.

Main Results and Discussion

Key performance highlights:

• Noise level within ±0.005 %T across 2100–2200 cm⁻¹ demonstrates exceptionally stable baseline.
• Detection of absorbance signals as low as 0.00023 AU in ATR oil stain analysis.
• High resolution separations at 0.25 cm⁻¹ resolve N₂O peaks near 2230 cm⁻¹, outperforming 1.0 cm⁻¹ settings.
