Getting a Clean Match in Forensic Toxicology using LC-MS/MS

Feb 6, 2017 | Blogs, Forensic | 0 comments

As a forensic scientist, what holds you back in the lab? It’s a question we often ask ourselves here at SCIEX, as product development depends on customer wants, needs, satisfaction, and ease of workflow. Ensuring evidence can withstand forensic scrutiny, for example, correlates with the integrity of testing procedures. Knowing this, how do you convince your staff to be confident in results, or convey technical data to a non-technical courtroom audience? If you have been left wondering how to get to the bottom of topics like these, check out the following toxicology toolkit. It’s a bundle of resources at your fingertips that includes a webinar led by Tania A. Saski Ph.D., Northwest Physician Laboratories, Bellevue, Using QTRAP® Technology to Provide Accurate Identification and Confirmation Beyond a Reasonable Doubt, and so much more.  Download Info Kit >

Tune in at your convenience to hear about her insights on four forensic cases with questionable results which were rectified using QTRAP® technology. When sample ratios are on the bubble and retention times vary, discover how LC-MS/MS can be a logical solution for difficult confirmations like opiate analysis. Gain higher confidence in your results and make it clear to everyone involved that you have a sample match.

In addition to the webinar, gain access to bundled application notes, a white paper, and in case you missed it, an e-seminar too. Want to get more insight into forensic applications? Visit, Border Security with Accuracy, Reliability, and Reproducibility.

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.
