Works well for many types of samples, can be hard to clean.
Application Area: Measure cheese for type of protein used to make it.
"Horizontal ATR worked well for samples such as cheese, grease, fat etc. Support was good when phoning for assistance. Only issue using this type of ATR was cleaning out liquids such as oils or honey, it was slow to clean and then dry solvent from all the parts of the crystal assembly. Pearl unit sounds better in this regard."
Specac’s Gateway™ ATR Accessory Kit is an economical multi-reflection horizontal ZnSe ATR accessory. With high-performance transfer optics and anti-reflection coated ZnSe crystals as standard, high optical throughput is achieved to facilitate an excellent standard of FTIR ATR spectral data.
The Gateway™ ATR Accessory Kit consists of: an optical unit; a trough top-plate with a 45° angle ZnSe crystal; a flat top-plate with a 45° angle ZnSe crystal; and, a clamp assembly. The trough top-plate is used for liquids and pastes analysis, and the flat top-plate and clamp assembly are used for solids and powders analysis. This accessory is simple to install and use in a wide range of spectrometer systems.
A wide range of interchangeable crystal ATR top-plates and sampling accessories can be used on the Gateway™ ATR Accessory optical unit to provide unrivalled multi-reflection ATR sampling versatility. These allow the Gateway™ ATR Accessory to be configured for the analysis of all types of samples (for example: solids, films, pastes, liquids) under a range of conditions (for example: static or flow conditions, and heating applications up to 200°C). All of the accessories are factory aligned.
All top-plates are fitted as standard with a 6 reflection ZnSe ATR crystal with a 45° angle of incidence, but other crystal materials and incident angles are available on request.
The Gateway™ ATR Accessory is a Benchmark™ baseplate compatible accessory.
Features and Benefits:
• High optical throughput
