Imagine being blindfolded, sent into a large (dark) room filled with obstacles and challenged to find an item, but you don’t know what that item is, and you have never seen it before. Then you must do the same again the next day, but you are looking for a different item, and it will be in a different place. The phrase fumbling around in the dark comes to mind!
Well, this is what it often feels like for forensic toxicologists trying to keep up with the unpredictable minefield of designer drugs — novel psychoactive substances (NPS).
NPS are synthetic chemicals, whether legal or illegal, closely related to known psychoactive compounds but with slightly altered composition. Not only does this make them difficult to recognize in routine screening, the fact that they are continually evolving – to evade regulation and defy law enforcement efforts — leaves drug screening labs in the dark on what compounds to target.
As if things aren’t tough enough, labs often receive wide varieties of sample types, ranging from blood and urine to hair and oral fluids, with complex biological components and challenging matrices. But it doesn’t stop there, some of these drugs are so potent that users only take a tiny amount, so the drug concentration is very low.
Fumbling around in the dark? Definitely! So, let’s remove the blindfold and shed some light on the matter.
Traditionally drug tests employ a range of targeted methods, and LC-MS/MS is recognized as one of the most efficient and reliable techniques available. The challenge is that these methods can only analyze known substances, limiting drug detection to compounds found on lists of pre-characterized analytes. In other words, if it’s not on the list, it won’t be seen.
How can toxicologists tackle the challenge of never-before-seen drugs? They need a screening tool that can detect trace amounts of unusual components in complex biological samples, even without any prior knowledge of their structural identities. This is the equivalent to removing the blindfold, turning the lights on, putting the obstacles aside and placing the item on a pedestal.
When our researchers here at SCIEX set out to do something, they don’t stop until they get there. As the opioid epidemic becomes the center of the drug overdose crisis, our team sought to develop a non-targeted screening workflow to screen novel fentanyl and its analogs in forensic biological samples.

The Echo® MS+ system is a novel platform for Acoustic Ejection Mass Spectrometry (AEMS) and combines the speed of acoustic sampling with the selectivity of mass spectrometry. This platform has been designed for high throughput analysis of small and large molecules. The technology combines Acoustic Droplet Ejection (ADE), an Open Port Interface (OPI) and could be coupled with the SCIEX Triple Quad 6500+ system or the ZenoTOF 7600 system.
The Echo® MS+ system comprises of an open-port interface (OPI) and acoustic droplet ejection (ADE) module which could be coupled with a mass spectrometer. The mass spectrometer could either be a SCIEX Triple Quad 6500+ system or the ZenoTOF 7600 system. This non-liquid chromatography based; high-throughput screening platform enables rapid analysis of compounds at speeds of up to 1 sample/second.
The ability to consistently achieve reproducible results on many complex samples across multiple days is critical to a routine clinical laboratory. Laboratories relying on analytical instrumentation require stability and robustness to perform a variety of screening and confirmatory assays with confidence. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) has become the preferred analytical method in the clinical laboratory to reliably perform clinical testing as it provides best-in-class performance and reliability for the most challenging assays. LC-MS/MS offers the required levels of sensitivity and specificity for the detection and quantitation of molecules from complex biological samples, helping laboratories deliver highly accurate data for a variety of clinically relevant analytes across a wide range of assays.
