Monitoring haemodialysis using electronic nose and chemometrics.

Development of Electronic Nose and Near Infrared Spectroscopy Analysis Techniques to Monitor the Critical Time in SSF Process of Feed Protein

In order to assure the consistency of the final product quality, a fast and effective process monitoring is a growing need in solid state fermentation (SSF) industry. This work investigated the potential of non-invasive techniques combined with the chemometrics method, to monitor time-related changes that occur during SSF process of feed protein. Four fermentation trials conducted were monitore...

Correlation of Sensory Analysis with Electronic Nose Data for Swine Odor Remediation Assesment

This article presents an evaluation of the electronic nose technology as an alternative to sensory analysis for assessing the effectiveness of biofilters. An AromaScan A32S electronic nose and a human panel at Duke University’s Taste and Smell Research Lab were used to measure typical volatile compounds from swine confinement buildings. Chemometrics techniques were employed to predict the olfac...

Electronic Nose Integrated with Chemometrics for Rapid Identification of Foodborne Pathogen

Discrimination of American ginseng and Asian ginseng using electronic nose and gas chromatography–mass spectrometry coupled with chemometrics

BACKGROUND American ginseng (Panax quinquefolius L.) and Asian ginseng (Panax ginseng Meyer) products, such as slices, have a similar appearance, but they have significantly different prices, leading to widespread adulteration in the commercial market. Their aroma characteristics are attracting increasing attention and are supposed to be effective and nondestructive markers to determine adulter...

Does chemometrics enhance the performance of electroanalysis?

This review explores the question whether chemometrics methods enhance the performance of electroanalytical methods. Electroanalysis has long benefited from the well-established techniques such as potentiometric titrations, polarography and voltammetry, and the more novel ones such as electronic tongues and noses, which have enlarged the scope of applications. The electroanalytical methods have...
