Traditional Omni-Cells vs the Pearl Accessory

29 Jun 2016

Traditionally, a vertically mounted liquid cell, such as the Omni-cell, was used to record IR spectral measurements. This application note shows how the Pearl™ Liquid Transmission Accessory has been designed to easily and quickly record highly repeatable IR spectral measurements for a wide variety of samples with high spectral resolution.
