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...Read More
Bone remains are one of the least characterized and most challenging matrices for forensic toxicological analysis. Before the forensic utility of the matrix may be fully realized, controlled experiments must be carried out. This presentation will highlight the value that UPLC-based approaches have brought to the drug analysis of bone samples. In addition, we will discuss the most recent findings in analytical developments using UPLC-QTof mass spectrometry, including: dramatic enhancements in sensitivity,...Read More

Dipsacus apser, or Japanese teasel, is commonly used in Chinese herbal medicine, often after rinsing with wine and then boiling with water. Researchers from Nanjing University of Chinese Medicine compared the differences between the composition of the raw herb and wine-processed material, using UHPLC-MS/MS and the chemometric methods PCA, HCA and PLS-DA.View All Ezines

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.View All Education Articles

Continuous improvements in GC/MS and LC/MS have revealed a stunning array of pharmaceuticals and personal care products (PPCPs) in municipal wastewaters. What is known from global studies is that exposure to biologically active compounds, even at ng/L concentrations, can impact endocrine systems in nature and manifest as negative impacts like altered gene regulation, the presence of mixed reproductive tissues (intersex) and skewed sex ratios. Advancing Canadian Wastewater Assets (ACWA) is a research...
