Assess the performance of the Echo® MS system
To obtain the best, most reproducible results using the Echo MS system, it is important to select the best solvent for your analyte and matrix and to ensure the flow rate is optimized for your solvent. Please review this flow rate optimization community post to calibrate your system to methanol for the system suitability test. […]

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.

Testing for pesticides in cannabis and hemp
As we all know pesticide and mycotoxin testing regulations differ in each state. The applicable pesticides used can differ by crop (hemp vs. cannabis) and pesticide effectiveness on cannabis and hemp in the first place is currently in doubt. Inside the laboratory, different extraction methods can lead to different recoveries and different instrumentation will have different detection limits.

The hidden ingredient in anti-fog sprays: PFAS
A recent study led by researchers from Duke University, conducted with colleagues from Wayne State University and the University of North Carolina at Charlotte, found that four of the top-rated anti-fog sprays contained up to 20.7 milligrams of per- and polyfluoroalkyl substances (PFAS) per milliliter of solution. This study has received a lot of exposure in popular media, and it should not be overlooked. The researchers used several creative approaches to obtain a comprehensive characterization of the anti-fog sprays, including using total organic fluorine measurements, GC-MS methods and both nominal mass and accurate mass instruments. A unique finding of the study was the detection of fluorotelomer ethoxylates (FTEOs), which are relatively unknown PFAS compounds.

Cannabis, sports and the World Anti-Doping Agency
We’ve all heard about the doping scandal that shocked the cycling world at the 1998 Tour de France, right? Well, because of that scandal, the International Olympic Committee (IOC) arranged a World Conference on Doping that brought together all parties involved in the fight against doping. The Lausanne Declaration on Doping in Sport1 was adopted by the conference in February 1999 and included a call for an international anti-doping agency to be operational for the 2000 Olympics in Sydney. The World Anti-Doping Agency (WADA) was established in November 1999 to answer that call.

Back to the new basics: Part 2 | Do I need a single quadrupole or a triple quadrupole system?
In this second installment of our 3-part “Back to the new basics” series, we continue to look at ways to improve lab productivity by using efficient techniques. The number of instrument options out there can be mind-boggling. Finding the right instrument—one that offers varying degrees of sensitivity, selectivity and specificity to meet your analytical needs—can be an intimidating challenge.
