Journal Highlight: Modeling of droplet traffic in interconnected microfluidic ladder devices

Date: Mar 19, 2012

Author:

Chinese scientists have developed an analytical model based on the electronic-hydraulic analogy to describe the hydrodynamic behavior of droplets in interconnected microfluidic ladder devices.

Caffeinated caffeine: Spotting the synthetic

Date: Mar 15, 2012

Author: David Bradley

Analysis of spectroscopic information has allowed researchers in Germany to determine whether a beverage contains natural or synthetic caffeine. The technique could let regulators check how well manufacturers of added-caffeine products are adhering to the rules regarding labelling products as "natural" with respect to the drink's caffeine content.

Testing times for TB: Statistics distinguish

Date: Feb 15, 2012

Author: David Bradley

Multivariate statistical data processing has been used to create a model from gas chromatography-mass spectrometry (GC-MS) data of metabolite profiles of the various types of Mycobacterium species tuberculosis (TB).

Journal Highlight: Chemometric analysis for optimizing derivatization in gas chromatography-based procedures

Date: Jan 23, 2012

Author:

Polish scientists have used principal component analysis to help optimize the derivatization of oestrogenic steroids such as estrone and estradiol prior to separation by gas chromatography.

Vendor Column: Designing a Standardized Laboratory Informatics Environment for Quality Operations

Date: Jan 16, 2012

Author: Chris Stumpf

Welcome to the second in a series of features from Chris Stumpf, a marketing manager at Waters Corporation who focuses on Lab Informatics. Every two months, Chris publishes a new informatics-related article which we hope will build into a worthwhile compendium of informatics material. This month, Chris describes the important concepts to consider when designing a standardized laboratory informatics environment operating in GxP.

Forensic fingerprinting: The smoking gun

Date: Jan 15, 2012

Author: David Bradley

UK scientists have used capillary-scale ion chromatography and suppressed conductivity detection to analyse gunshot residues, sweat and latent fingerprints. The statistical techniques used to extract the data can reveal whether fingerprints were left by someone who fired a gun and even whether or not they smoke.

Polycyclic aromatic hydrocarbons: heavy testing

Date: Dec 13, 2011

Author: David Bradley

Complex heavy fuel oil mixtures can be analysed for their polycyclic aromatic hydrocarbon content using multivariate curve resolution and alternating least squares on their chromatographic and mass spectrometric data, according to research published in Analytical Chemistry.

Journal Highlight: Chemometric analysis of gas chromatographic data - investigation of enological parameters of a bag-in-box white wine as affected by storage time and temperature

Date: Dec 12, 2011

Author:

Score plots from the principal component analysis of gas chromatography data for wine extracts showed grouping trends that were influenced by storage time and temperature. PCA loading plots revealed that changes in chemical profiles were different for wines held at different storage temperatures. Storage time could be predicted accurately by partial least squares regression of the GC data, and, in general, the enological parameters could be predicted accurately from GC fingerprints.

Journal Highlight: Characterization of a comprehensive flavor database

Date: Nov 17, 2011

Author:

The highly complex and multidimensional nature of flavor perception challenges our ability to both predict and design new flavor entities. Toward this endeavor, classifications of odor descriptors have previously been proposed. In this work, the authors developed a fingerprint-based representation of a large data set collected from many sources over the course of more than 40 years.
