With innovative optical design and durable monolithic diamond ATR crystal option, this sets the benchmark in performance and value for ATR spectroscopy.
High-throughput single reflection ATR.
Interchangeable crystal pucks.
Pressure tower for repeatable load application.
All-reflective optics for wide spectral range.
Interchangeable ATR-FTIR crystal pucks
Various interchangeable ATR crystal pucks are available for the Quest.
- High throughput diamond
- Extended wavelength diamond
- ZnSe
- Ge
- Silicon
- Specular Reflectance
- Arrow
| Material | Range (cm-1) | Refractive index | Depth of penetration* (µm) |

| Ge | 5500-480 | 4.00 | 0.7 |
| Si | 8000-1350; 500-33 | 3.41 | 0.9 |
| Arrow™ silicon wafer | 8000-33 | 3.41 | 0.9 |
Heated puck
The Heated Puck enables high temperature measurements up to 110 °C, perfect for analysis of phase changes in soaps, food stuffs, and other multi-phase systems. A highly sensitive 4-wire RTD sensor is used for temperature measurement, while control is provided by a compact USB interface and a free PC-based software app.
The heated puck is available with either a high throughput diamond ATR crystal or a ZnSe crystal.
Pucks for easy liquid sampling
Liquid pucks have a raised surface around the crystal, forming a bowl to confine samples on the crystal. This is useful for samples with low viscosity or prone to evaporation. The bowl has a volume of approximately 100 µL.
The pressure tower
The Quest™ has a pressure tower which allows a clamping load of up to 40 lbs to be applied to solid samples to ensure full contact with the crystal. The tower gives an audible click when its pre-set load has been reached.
Flow anvil
The flow anvil enables samples to be flowed over the crystal at low flow rates and low pressures using a syringe. It has an internal volume of 28 µL and is held in place with the pressure tower.
Compatible with measurement standards

Quest ATR accessory reviews
"We have been testing liquids, powders (deposits) and plastics with absolutely no problems for the last 3 years" – Marco Nunes of Cariri
"Of particular note is the use of all-reflective optics and the availability of an extended-range diamond option" – Philip Ash of University of Oxford
"These diamond ATR units are practically indestructible and extremely easy to clean and can be swapped out for liquid or gas cells very easily" – Susan Gannon of University of Glasgow
"Perfect for organic chemistry practicals" – Peter Brien of Trinity College Dublin
