Diamond ATR Top-Plate

Outstanding sensitivity is achieved using a high pressure contact against a solid, type IIIa diamond, selected for unparalleled sensitivity and unique physical and chemical stability. The accessory can be used to analyse a range of samples from single particles and fibres to corrosive liquids, while the large working area sample platform is ideal for macro sampling.

Germanium ATR Top-Plate

The high refractive index of germanium, 4 at 1000cm-1, makes this ATR material an ideal choice for these samples containing high concentrations of carbon black. Optimum sensitivity is achieved using a 4x4 mm germanium crystal cemented into a rugged stainless steel disk for maximum strength and support.

The shallow depth of penetration with no band distortion overcomes difficult quantitative analysis of strongly infrared absorbing materials. Similarly, corrosive samples, thin films and surface coatings can also be analyzed.

Heated ATR Top-Plate

Many reactions and processes occur at high temperatures. The Heated Top-plate includes all the normal features of the Golden Gate sampling technique, but it has the added capability of heating samples up to 200 ºC.

High Temperature ATR Top-Plate

Many reactions and processes occur at high temperatures. The High Temperature Diamond Top-plate includes all the normal features of the Golden Gate sampling technique, but it has the added capability of heating samples up to 200 ºC.

Low Temperature ATR Top-Plate

The Golden Gate™ Low Temperature single reflection diamond ATR system is the first ATR accessory to provide high performance ATR measurements down to near liquid nitrogen temperature. The system uses a thermally insulated copper and stainless steel Dewar in conjunction with an integral heater. The high thermal conductivity of the diamond ATR crystal provides rapid temperature stabilisation, accurate temperature measurement and avoids temperature gradients across the sample.

Micro-Specular Reflectance ATR Top-Plate

A 45° angle Micro Specular Reflection Top Plate is for flat samples greater than 2mm x 2mm, or powders that can be pressed into a self-supporting wafer. A scribed reference grid allows accurate repeat positioning of samples.

Reaction Cell ATR Top-Plate

The Reaction Cell allows in-compartment reaction monitoring over a broad range of extreme conditions. The diamond is metal bonded into a tungsten carbide mount and this is contained within a high pressure reaction vessel. The unique strength and durability of the diamond element makes it ideal for withstanding combinations of aggressive chemical contact at high temperatures and pressures.

Supercritical Fluids ATR Top-Plate

The Supercritical Fluids Analyser version of the Golden Gate™ ATR is designed for operation at extreme temperatures and pressures. 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 runaway protection system to prevent thermal runaway.

Anvils
  • Golden Gate Micro-Flow Cell Anvil This Micro-Flow Cell anvil seals under pressure around the diamond. Its volume is 28 microlitres and it can operate at 1000 psi. It may be used as a flow cell or as a micro reaction chamber. GS10568
  • Golden Gate Narrow Gauge Grooved Anvil In the study of coating on wires the grooved anvils hold the wire exactly in the middle of the diamond. This narrow gauge anvil is for the Golden gate Mk II ATR. GS10547
  • Golden Gate Pellet Anvil Polymer pellets are held firmly in position with this concave anvil. With a flat anvil they could move when pressure is applied. GS10532
  • Golden Gate Reactive Sample Anvil Samples which are sensitive to air or moisture can be loaded and pressed in a dry box. The anvil has a seal which compresses as the sample is pressed, thus keeping it in an inert environment while the spectrum is being run. GS10536
  • Golden Gate Sapphire Anvil The Sapphire anvil has the advantage of being very hard, and easy to clean to prevent sample carry-over. It is also self-levelling to accomodate irregular samples. GS10531
  • Golden Gate Stainless Steel Flat Anvil This is used for fibres or fine wires. It is not self-levelling, which is an advantage with this type of sample. GS10549
