Golden Gate Single Reflection Diamond ATR

Golden Gate Single Reflection Diamond ATR Accessory

The Golden Gate has proven to be the world’s most robust and versatile Single Reflection Diamond ATR accessory for analytical sampling under extreme conditions. It is the only Diamond ATR accessory that is precision designed and engineered to perform at cryogenic temperatures down to -150°C and at elevated temperatures up to 300°C with added feature of supercritical fluid pressures up to 6000 psi using the appropriate top plates.

The standard unit is provided with a 2 x 2mm 45 degree single reflection Type IIIa Diamond brazed within a Tungsten Carbide sample mount. The optical path directs the energy to an active sample area of 0.60mm in diameter. The accessory includes a novel swing bridge with a mounted Sapphire anvil for controllable and reproducible high pressure contact up to 180 lbs. The anvil has a clear working distance of 6mm for macro samples and is mounted into a non-rotating clamp to avoid sample shear and heating by friction. ZnSe is provided as the standard infrared transmitting focusing element with KRS-5 available for extended spectral performance. Scroll below for order details.

The Diamond ATR Top Plate is ideal for applications with highly absorbing samples, polymer pellets, hard or opaque solids, single fibers and microscopic particles, corrosive liquids and analysis for most samples normally requiring the use of an FTIR microscope or high pressure diamond anvil cell. You can choose from a variety of sample specific anvils such as the popular micro reaction flow cell anvil and view-thru anvil. You may refer to this Product DataSheet to assist with ordering the items below. Recall to specify your spectrometer make and model.

For more demanding applications, options include a Germanium top plate, 200°C or 300°C heated Diamond top plate, 200°C and 3000 psi Diamond Reaction Cell, -150°C to 80°C Diamond Low Temperature top plate, 6000 psi and 300°C Supercritical Fluids top plate, and a Micro Specular Reflectance top plate. All top plates are interchangeable with the Golden Gate’s optical base unit and can be purchased individually. CLICK HERE for a summary brochure.

For less demanding sample analysis, the less expensive Quest Single Reflection Diamond ATR accessory may be suitable. REFLEX Analytical welcomes your contact to discuss your application demands.
