(Quest ATR) ATR: A Tool for Botanical and Ecological Analysis

Plant samples are easily analyzed using ATR-FTIR spectroscopy on the Quest™ ATR Accessory.

The different chemical makeup of leaves, petals and even pollen may be detected using infrared spectroscopy. Traditionally, wet bio-samples like leaves had to be dried and ground with KBr to make pellets.

These would then be pressed and placed in a spectrometer. This is a very slow and outdated method of analysis and requires a lot of sample preparation. Conversely, attenuated total reflectance (ATR) requires no sample preparation and is a fast way of analyzing multiple samples. Moreover, modern ATR accessories like the Quest™ can handle wet samples like plants easily. This note describes the simple analysis of Winter Rose buds of different ages.
