The Spectrum Two is a versatile Fourier Transform Infrared (FTIR) spectrometer designed for a wide range of materials analysis. It offers several sampling accessories to accommodate various sample types, thicknesses and techniques:
Universal Attenuated Total Reflectance (UATR):
This method facilitates rapid analysis of thin films (down to microns), opaque solids, liquids, and powders. It covers a wavenumber range of 450-4000 cm⁻¹ (22 µm to 2.5 µm).
Transmission:
Analyse thin films (less than 100 microns) deposited on transparent mid-infrared substrates or analyse powdered samples mixed with KBr. The transmission mode operates within the 400-4000 cm⁻¹ (25 µm to 2.5 µm) range.
Fixed-Angle Specular Reflectance:
This technique is suitable for measuring any flat film, metallic surfaces, or reflecting surfaces. Measurements are conducted at a fixed 16° angle of incidence across the 450-4000 cm⁻¹ (22 µm to 2.5 µm) range. The accessory includes a flat reference mirror and aperture masks (2mm, 5mm, and 10mm) for versatility.
Diffuse Reflectance:
This method is ideal for analysing highly scattering solids and powders. It operates within the 450-4000 cm⁻¹ (22 µm to 2.5 µm) range and comes with two sampling cups with micro (~20mg) and macro (~80mg) capacities.
The Spectrum Two caters to a broad spectrum of samples, including:
- Organic powders, liquids, and films
- Biological sections
- Minerals
- Polymers
