It’s Time to Enhance Your Food Testing

Dec 6, 2016 | Blogs, Food / Beverage | 0 comments

Are you looking for ways to up the ante on your LC-MS/MS when it comes to food testing? Researchers here have developed a method for the analysis of approximately 400 pesticides in food samples, and their work is available for viewing in this year’s compendium. This application note is just one of 16 you will find under Pesticides >

Using your QTRAP® LC-MS/MS System at its Full Potential Overview
Using MRM mode, the QTRAP® 6500 LC-MS/MS was used to quantify hundreds of pesticides in food samples with high selectivity and sensitivity. Identification was further confirmed using MRM ratio identification. An alternative approach for compound identification went beyond the detection of multiple fragments.

Details of Experiment
Twenty pesticides were spiked into different food samples, and diluted extracts were analyzed using two methods.

Results and Conclusions
Improved data processing using a dual injection approach with automatic quantitation, identification, and confirmation using MasterView™ and MultiQuant™ Software. Results highlight the complementary nature of MRM ratios and MS/MS full scan offering a possibility of confirmatory analysis. 

Telling the PFAS story with pine needles

As an ever-expanding group of chemicals, per- and polyfluoroalkyl substances (PFAS) require novel techniques to monitor their current and historical presence in the environment. Concerns over exposure to PFAS chemicals continue to grow, with some having known toxic characteristics and the potential effects of others remaining unknown.1 In addition, while PFAS are one of the most persistent synthetic chemicals to date, most of them hardly degrade in the environment.2 So, how long do traces of PFAS last in our environment? Two tools used to help answer this question are active samplers and passive samplers.

Back to the new basics: Part 3 | LC vs. LC-MS and what it means for your lab

In this final installment of our “Back to the new basics” series, we take one more look at analytical techniques and best practices in the lab, and opportunities to improve efficiency. Here, we explore the basic principles of high-performance liquid chromatography (LC) and liquid chromatography mass spectrometry (LC-MS), and how these techniques can affect a lab’s efficiency and productivity.

Meat vs plant based. What is the best option?

As we become more conscious about the planet, healthier lifestyles and our duty to protect the environment, attitudes and behaviours are shifting when it comes to food consumption.
