ABSTRACT: Owlstone’s portable instrument quantifies concentrations of in-process chemicals of interest (such as diacetyl), raw material contaminants, CIP residues, flavor mal odors, VOCs, and much more in real time (within seconds) at ppb/ppm levels. The instrument platform is Owlstone’s FAIMS-based system (“field asymmetric ion mobility spectrometry”). FAIMS is a detection technology that separates and identifies chemical ions based on their mobility under a varying electric field at atmospheric pressure. Utilizing its proprietary FAIMS-based platform, Owlstone Inc. has created Lonestar, a portable rapid detection instrument. The heart of the Owlstone FAIMS detection technology and the Lonestar instrument is a dime-sized, silicon chip spectrometer. Multiple analytes can be identified and quantified within seconds at low trace concentrations. The instrument is portable and is designed to be operated by non-technical personnel. At the push of a button, non-technical production staff is able to identify and quantify chemicals of interest right at the point of need in the brewery. Some of the applications discussed include the real-time detection of diacetyl, amyl acetate, acetaldehyde, raw material contaminants, flavor mal odors, and water residues.
