 Sampling accessories for spectroscopy

Anadis distributes a vast range of custom made, high quality, sampling accessories for spectroscopy, made bij Harrick Scientific, a leading company in this area. The use of these accessories greatly enhances the performance of spectrometers. The available options have moved far beyond the days of traditional transmission sampling methods like KBr pellets and salt tablets. The four sampling techniques commonly used in combination with UV/Vis, NIR and FTIR are:

• Transmission
• Specular reflectance (specular, grazing angle)
• Diffuse reflectance (with integrating sphere or polarized)
• Attenuated total reflectance (with different crystals)

Gasses can be measured in transmission with a gas cell, however also thin film polymer samples produce excellent quantitative and qualitative results using this mode.

Specular reflection is used to measure thin and thick films as well as for relative reflectivity of mirrors with or without polarization.

Diffuse reflection can  be applied to measure food, feed, powders and polymers.

ATR is a versatile sampling method applicable for powders, liquids and solids. Different sample conditions are possible making it possible  to study product changes in real-time. It requires no sample preparation at all.

Many sampling accessories are available with temperature and pressure control.

Well-known accessories are: SplitPea, Horizon, Praying Mantis, Seagull and Environmental Cell
