Abnormal salivary proteins in autism
Date: Jan 15, 2009
Author: David Bradley
A saliva test for autism spectrum disorder (ASD) is being developed by researchers in Italy. Their test involves a sophisticated mass spectrometric analysis and associated statistical analysis of the data. It could provide researchers with a useful biomarker approach for a subgroup of ASD patients.

Cutting useless variables in heroin analysis
Date: Dec 15, 2008
Author: David Bradley
Researchers in Spain have developed a way to eliminate uninformative variables from the multivariate calibration of near-infrared spectra and so allow a more productive determination of heroin in illicit street drugs to be carried out.

In-line monitoring of reactive crystallization process based on ATR-FTIR and Raman spectroscopy
Date: Sep 17, 2008
Author:
Glutamic acid is an industrially important amino acid which is mainly used as a food additive and in pharmaceuticals. This paper studies the utilization of attenuated total reflectance-Fourier transformed infrared (ATR-FTIR) and Raman spectroscopy to investigate isothermal semi-batch precipitation of a model compound, L-glutamic acid.
