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...

Last Month's Most Accessed Feature: LC-MS/MS shines light on sunscreen UV filters

The detection of UV filters, used in sunscreens and other cosmetics, is a topic of interest for analysts working on their possible health effects, for those concerned with consumer protection and also for environmental scientists, since these products can have adverse environmental consequences, such as damaging coral. Scientists in Beijing have developed an improved method for detecting a range of different UV filters using LC-MS/MS.

In the context of the European project μAqua, UPLC/MS/MS and flow cytometry were used to confirm the presence and wide distribution of dihydro derivatives of anatoxin-a toxins in European freshwaters.

Spanish scientists have synthesized a propazine-imprinted polymer on the surface of modified magnetic nanoparticles for use in the solid-phase extraction of triazine pesticides from soil samples prior to analysis by HPLC.

Whether you love it or loathe it, you may well want to know how much of that hot pepper taste is in the food you buy. Scientists from Brussels, Tokyo and Osaka have developed a novel HPLC method using coulometric detection to quantify capsaicinoids, the compounds that give the hot sensation.

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.

Analytical Chemistry to Quantify Municipal Wastewater Treatment Technology Performance and Benefits to Environmental Health

Date: May 24, 2017 - 15:00

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...
