Last Month's Most Accessed Feature: Fabric sweat testing: Armpit excretions distinguish material and gender

The sweat volatiles that escape from armpits onto clothing that were analysed by 2D-GC/MS can be used to distinguish between the types of fabric and examine the effects of washing, while also revealing the gender of the subjects.

Analysis of Environmental Contaminants in Water Using an Agilent 6470 LC/TQ Instrument

The analytical demands for detecting organic contaminants in water at low ng/L level have pushed the development of new methodologies using LC/TQ instrumentation. In this regard, and in the last few years, advances in sensitivity and selectivity have made this challenge possible. This webinar will focus on the use of the new 6470 LC-MS-MS from Agilent Technologies for the sub ng/L level detection of several pharmaceuticals and pesticides in surface waters. Examples of optimization of several source...

Mosquito species can be differentiated using their proteins which are identified by MALDI TOF mass spectrometry, providing a rapid and reliable way to identify disease vectors and form the basis of an international database.

The use of mass spectrometry for measuring compositional differences among manufactured allergen extracts has been described using house dust mite allergen extracts as a prototypical complex extract that may be standardized.

Multiple mycotoxins can be measured in blood spots and serum spots by LC/MS say European scientists, providing a more accurate way to estimate individual dietary exposure from contaminated food.

Selected key technologies of the analytical science industry are discussed by Steve Down with reference to burgeoning application areas and the scope for future improvements.

Ion source pressure plays a significant role in the process of ionization and the subsequent ion transmission inside a mass spectrometer. Pressurizing the ion source to a gas pressure greater than atmospheric pressure is a relatively new approach that aims to further improve the performance of atmospheric pressure ionization sources. A brief review on the development of super-atmospheric pressure ion sources, including high-pressure electrospray, field desorption and superheated ESI, and the strategies to...

In the current context of international conflicts and localized terrorist actions, there is unfortunately a permanent threat of attacks with unconventional warfare agents. Among these, biological agents such as toxins, microorganisms, and viruses deserve particular attention owing to their ease of production and dissemination. Mass spectrometry-based techniques for the detection and quantification of biological agents have a decisive role to play for countermeasures in a scenario of biological attacks.
