Case Study: LC-MS/MS Online Sample Preparation for Water Analysis

Learn how one of Canada's major Universities improved LODs by 100x and reduced sample preparation to about 15 minutes.

Introduction

The Environmental Analytical Chemistry Laboratory at the University of Montreal comprises approximately 20 researchers focused on finding the best analytical methods for environmental studies. The laboratory is currently collaborating with the City of Montreal, the Drinking Water Research Chair at the Ecole Polytechnique de Montreal, and Environment Canada in order to identify and quantify pharmaceutical residues in the city's waste and drinking water. To conduct this research, the University has developed a new online sample preparation method using a customized Thermo Scientific EQuan system for solid phase extraction coupled to liquid chromatography and tandem mass spectrometry (SPE-LC-MS/MS) analysis.

Case Study: LC-MS/MS Analysis of Antibiotics in Honey

Learn how scientists at the Korea Beekeeping Association (KBA) screen for 50 antibiotics and pesticide residues in honey with Thermo Scientific TurboFlow technology.

Introduction

Increasing concern over the presence of antibiotics and pesticide residues in foodstuffs and the related potential health threats to humans have required food quality control laboratories to develop fast and efficient methods of detecting these contaminants. Some of the challenges facing these organizations include their need for multi-component quantitation, preference for simple sample preparation, and desire for an automated, online method to make quality control screening cost-effective.

Case Study: LC-MS/MS Detection of Melamine

Read about why the National Center for Food Safety and Technology used the TSQ Quantum Ultra to develop a new method for the detection of melamine in food.

Introduction

When the presence of melamine was discovered in animal food sources in early 2007, the National Center for Food Safety and Technology (NCFST) needed to quickly learn more about the effects of food processing on the chemical to learn how to accurately detect the presence of melamine in food. The NCFST in Chicago, Illinois, is a research consortium involving the U.S. Food and Drug Administration's (FDA) Center for Food Safety and Applied Nutrition (CFSAN), the Illinois Institute of Technology (IIT) and the food industry.
