Golden Gate™ Single Reflection Diamond ATR Series MkII

Golden Gate™ Single Reflection Diamond ATR Series MkII

The Golden gate diamond ATR is high performance and the world's most versatile ATR. It analyzes all types of samples, from hard solids to corrosive liquids, and it is easy to use, sensitive, and robost.

It is available with various types of top plates for different applications:

  • High temperature top plate (heatable to 300 °C)
  • Low temperature top plate (from -150 °C to 80 °C)
  • Reaction cell (pressure up to 3,000 psi)
  • Supercritical fluid top plate (pressure up to 6,000 psi and temperature up to 300 °C, low volume 28 μl stainless steel sample cell)
  • Micro specular reflectance top plate for flat samples of greater than 3 mm x 6 mm, or powder that can be pressed into a self-supporting wafer

Key Features

  • High sample throughput
  • Rugged type IIIa diamond ATR metal-bonded into a tungsten carbide mount
  • Hard, inert, sapphire self-levelling pressure anvil
  • Pressure bridge with safety interlock
  • Built-in pressure control for reproducible results
