Arrow - a revolutionary new consumable ATR Solution - Zero Cleaning, Zero Risk, Zero Hassle

Arrow™ is a revolutionary new consumable ATR solution with applications ranging from testing of chemically aggressive samples through to large scale batch testing of liquid samples and solids dried from solution. Arrow consists of a thin Si ATR element fixed into a plastic slide for mounting on the Quest™ ATR unit. It also enables the slides to be conveniently handled and stored without coming into contact with the sample area. The slide is made from 100% recycled polypropylene.

Arrow guarantees there will be no cross contamination between samples. When samples have been analysed the Arrow slide can be disposed of in accordance with local regulations or retained for future reference.

The list of applications is endless including extended duration tests, forensics, life Science, pharmaceutical, clinical. Petrochemical, paint/coatings and glues

Here we demonstrate the suitability of Arrow for batch testing of samples in the food and drink industry.

Accurate quantification of the composition of food and drink is essential for compliance with local regulations on labelling of goods for general sale and for correct application of customs duties when imported. Food and drink labelling should provide correct information about calorific and nutritional content to help people stay within recommended limits.

Solutions of water/ethanol in 26 different concentrations were prepared. A batch of Arrow™ slides were filled with aliquots from each solution and then covered with the Arrow™ sample cap to prevent evaporation. One slide was retained for use as a background. The prepared batch was then transported to the spectrometer for analysis.

Spectra were recorded on a commercially available spectrometer. The background spectrum was recorded first, followed by each of the 26 Arrow™ sample slides in turn. The complete procedure takes less than 10 minutes because there is no wipe down and cleaning of the sampling point is required between each spectral acquisition.

Quest – still the best selling ATR in the Universe !! Have you got yours ?

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 of the Quest™ ATR are the Monolithic diamond ATR crystals that are both chemically resilient and scratch resistant, as well as extremely tough.

We now have 7 Interchangeable crystal pucks and we will be introducing the heated puck this year. Our ever-growing range of options currently includes ZnSe for soft materials, Ge for highly absorbing samples, and options for liquid containment and specular reflectance.
