Near-Infrared Spectrometer S450 | AELAB

Overview

Product Overview

The AELAB S450 is a Near-Infrared Spectrometer covering a wavelength range of 900~2500nm, corresponding to the catalog-specified 11000-4000 cm^-1 range. It is designed for NIR measurement without sample preparation, and the catalog states that the sample is not damaged during measurement.

The S450 uses an integral-sphere diffuse reflection sampling system that collects diffuse reflected light from multiple angles. This configuration is intended to improve measurement reproducibility when measuring uneven samples.

Multiple sample cups and accessories are available for particle, powder, liquid and film testing. The specified analysis time is about 1 minute, with wavelength accuracy of ≤0.2nm and wavelength repeatability of ≤0.05nm.

Key Features

• No Sample Preparation: The catalog states that no sample preparation is required and the sample is not damaged.

• Integral-Sphere Sampling: Uses an integral-sphere diffuse reflection sampling system with multi-angle diffuse reflected light collection.
• Traceable Wavelength Calibration: Each instrument uses multiple traceable standards, with calibration points distributed across the complete wavelength range.
• Wavelength Accuracy: ≤0.2nm.
• Wavelength Repeatability: ≤0.05nm.
• Optical Components: The catalog lists tungsten lamps, filters, gold-plated gratings and refrigerated indium gallium arsenide detectors among the instrument’s core components.
• Multiple Sample Formats: Sample cups and accessories are available for particle, powder, liquid and film testing.
• Environmental Monitoring: Ambient temperature and humidity are monitored in real time and stored in the spectrum file.
• Software Compatibility: Data files are compatible with Unscrambler.

Applications

• Particle Samples: Near-infrared measurement using suitable catalog-listed sample cups and accessories.
• Powder Samples: NIR measurement of powder-format samples.
• Liquid Samples: NIR measurement using suitable liquid-sample accessories.
• Film Samples: Near-infrared measurement of film-format samples using suitable accessories.

Integral-Sphere Diffuse Reflection Sampling

The S450 uses an integral-sphere diffuse reflection sampling system. Diffuse reflected light is collected from multiple angles, which the catalog states is more conducive to improving measurement reproducibility for uneven samples.

Wavelength Calibration and Measurement Performance

Each S450 uses a variety of traceable standards for wavelength calibration. The calibration points are evenly distributed across the full wavelength range to support consistent wavelength accuracy between instruments.

• Bandwidth: 12nm
• Wavelength Range: 900~2500nm
• Wavelength Accuracy: ≤0.2nm
• Wavelength Repeatability: ≤0.05nm
• Stray Light: ≤0.1%
• Noise: ≤0.0005Abs
• Analysis Time: About 1 minute

Temperature and Humidity Monitoring

The S450 monitors ambient temperature and humidity in real time. The environmental information is stored in the spectrum file so users can review the measurement conditions associated with spectral data and use that information when checking or optimizing measurement conditions.

Software and Data Compatibility

The catalog states that the S450 software is simple to operate and that its data files are compatible with Unscrambler.

Important: The standard package does not include Unscrambler software. The catalog also states that the instrument and software do not include a database for principal component analysis.
