Food Analysis

Introduction to the Rapid Evaporative Ionization Mass Spectrometry (REIMS) Technique: Fundamentals and Applicability to Direct Food Analysis

Rapid Evaporative Ionisation Mass Spectrometry (REIMS) is an emerging technique that allows direct characterization of biological tissues, food and environmental samples without the requirement for sample preparation in near-real time.


In this on-demand presentation you will learn about the origins of the REIMS technology and commercial development, the technology hardware and software fundamentals, the characteristics of the technique and the applicability of REIMS for a wide variety of food and environmental applications.



Sara SteadSara Stead gained her PhD in analytical chemistry from the University of York, UK; the title of her thesis is “Development and validation of rapid screening assays for the detection of veterinary pharmaceuticals in foods of animal origin.” Sara has worked in the area of consumer safety focusing on the detection of chemical residues and environmental contaminants in food destined for human consumption for the past 15 years in both the government and private sectors.

In her position at Waters Corporation, Sara is responsible for strategic collaboration development for the food and environment market sector. Sara has a number of research and application interests including the development of multi-residue HRAM screening methods for chemical residues and natural contaminants. Currently Sara is working on the development of innovative solutions for the detection of food fraud & authenticity using MS based techniques including REIMS with iKnife technology.

Prior to joining Waters, Sara was employed as a senior scientist at the Food and Environment Research Agency (Fera, Defra, UK) and was responsible for the development and validation of numerous methods for analysis of food and environmental samples. Sara has participated in FVO audit inspections acting as the independent laboratory expert and is a member of the EuroResidue conference scientific committee. Sara has also participated in various EU funded collaborative projects including ISOSTER, BioCop and Conffidence.
