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.
Steven Freshman, global GM for Owlstone, is responsible for FAIMS partnering and installation efforts globally for Owlstone’s Industrial Process Control applications across the brewing, food, pharmaceutical, and oil and gas industries.
