Quest, the universally best selling single reflection ATR

The Quest™ ATR is a single-reflection ATR accessory from Specac designed for routine use in academic and industrial laboratories. With features designed to inspire confidence in the quality of results and reliability in use, this product sets the benchmark in performance and value in FTIR-ATR Spectroscopy. 

The key features are the monolithic diamond ATR crystals that are both chemically resilient and scratch-resistant, as well as extremely tough, being able to sustain the high point loads encountered when sampling hard, irregular solids. Interchangeable crystal pucks. Specac’s ever-growing range of options currently includes ZnSe for soft materials, Ge for highly absorbing samples, and options for liquid containment and specular reflectance. 

Repeatable and reproducible sample loads are enabled by the pressure tower. This has an audible 'click' to indicate the preset pressure limit and features a swing anvil arm to allow easy access to the ATR crystal puck. Both plane and pellet anvils are provided with the accessory to allow analysis of samples of various shapes. These anvils are easily interchangeable and stored on the top plate when not in use.

The Quest was successful in helping Staffordshire Police analyse twelve drug samples taken from a UK music festival. The samples were analysed by Staffordshire University in collaboration with Staffordshire Police to determine which narcotics they contained. Approximately 1 mg of each sample was placed onto the Quest ATR, without any sample preparation. The Quest ATR was mounted in a commercially available spectrometer and spectra of the drugs were recorded.

The Quest is also used by border protection and security services who stop and search criminals and rely on these tests to determine what certain substances are. Drugs, blood and semen are often found at crime scenes and several forensic analyses exist to test them.
