The RAY-30 Infrared Oil Meter is a versatile instrument designed for recording both IR absorption and (with accessories) IR reflection spectra within the range of 4000 cm⁻¹ to 400 cm⁻¹ (wavelengths from 2.5 μm to 25 μm). It allows users to perform either qualitative or quantitative analysis on samples using stored or plotted spectra. This device is widely used in various fields such as petrology, chemical industry, medical research, food safety, paper production, environmental monitoring, semiconductor manufacturing, and more, making it an essential tool for material structure analysis. **Specifications and Performance Index** 1. **Basic Parameters** - Wavenumber Range: 4000 cm⁻¹ to 400 cm⁻¹ - Transmittance Scale: 0% to 100% (expandable to -400% to 400%) - Absorbance Scale: 0 to 1A (expandable to -4A to 4A) - Wavenumber Expansion Option: 4000 cm⁻¹ to 400 cm⁻¹ - Transmittance Expansion Option: -400% to 400% - Single Beam Expansion: -400% to 400% - Scan Time for Full Range: Approximately 2.5 to 25 minutes (in fast response mode) - Slit Program: 5 slit widths – Very Wide, Wide, Normal, Narrow, Very Narrow - Dimensions: 800mm × 610mm × 300mm - Weight: Approximately 100 kg - Power Supply: 230V, 50Hz ±1Hz, 200W 2. **Main Performance Index** - Wavenumber Accuracy: ±4 cm⁻¹ (4000–2000 cm⁻¹); ±2 cm⁻¹ (2000–400 cm⁻¹) - Wavenumber Reproducibility: 2 cm⁻¹ (4000–2000 cm⁻¹); 1 cm⁻¹ (2000–400 cm⁻¹) - Transmittance Accuracy: ±0.2% (excluding noise) - Transmittance Reproducibility: Less than 0.4% (1000–930 cm⁻¹) - Baseline Flatness Before Correction: Less than ±4% - Resolution: For polystyrene, six absorption peaks near 3000 cm⁻¹; sixth peak height above 2%.
