Golden Gate | Low Temperature ATR

A low-temperature, high performance, FTIR accessory developed for the study of liquid and solid samples at low temperature. Based on the Golden Gate single-reflection diamond ATR accessory platform.

High performance ATR measurement for low temperatures: The low temperature range is from -150°C to 80°C. The system uses a thermally insulated copper and stainless steel dewar in conjunction with an integral heater.

Robust construction: The diamond ATR element is high temperature metal bonded into a tungsten carbide disk, avoiding the use of adhesives or resins that may be dissolved or attacked by the chemical aggressiveness.

Meer informatie over Golden Gate | Low Temperature ATR

The high thermal conductivity of the diamond element is ideal for fast temperature equilibrium and accurate temperature measurement, reducing analysis time and increasing sample throughput. The analyser is equipped with a thermal protection system to prevent thermal runaway.

Specifications

ATR crystal	Monolithic diamond
Crystal sealing	The diamond is sealed with a metal braze into a tungsten puck.
Angle of incidence	45^o
Spectral range	ZnSe lenses 5000-700 cm^-1KRS-5 lenses 6500-400 cm^-1
