Gateway | Multi-reflection HATR accessory

The Gateway ATR is a 6-bounce multiple reflection ATR accessory designed for improved signal-to-noise resolution on low intensity peaks in your spectrum compared to single bounce accessories. Interchangeable Top Plate Options 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 sampling versatility. Analyse liquids, pastes and solids under static, flow conditions from ambient to 200 °C.

• Flat Top Plate (supplied as standard)

For pastes, viscous fluids and solids (with supplied clamp) under static conditions and ambient temperature.

• Trough Top Plate (supplied as standard)

For Liquids and pastes nder static conditions and ambient temperature.

• Electrically Heated Trough Top Plate

For studying samples under static conditions from ambient to 200 °C.

• Water Heated Trough Top-Plate

For studying samples under static conditions from sub-ambient to 90 °C. Requires thermocirculating bath. (LINK?)

• 550 μL Flow Through Top Plate
