Forensics depend on detection of even the smallest compounds to deliver results you can rely on. You need fast analysis methods that provide highly accurate data across a multitude of compounds and biomarkers, which enable you to uphold result integrity and get the truth from your samples.
Mass spectrometry has become fundamental to the evolution of forensic science. As instruments have become more sophisticated, law enforcement can now get results from the smallest samples of lingering traces of crime, in a manner that will stand up in court. However, the ever-increasing sensitivity and throughput requirements of forensic assays can pose method development challenges, even for the most powerful LC-MS/MS technology.
Getting the Right Answer is Crucial to Your Forensic InvestigationAs with many applications of quantitative analysis, forensic analytes can be difficult to accurately detect because of complex matrices or the presence of chemical interferences. Furthermore, compounds may be isobaric and consequentially challenging to separate with conventional separation technology.
Where LC-MS/MS sensitivity alone is not enough for complex assays that demand exceptionally selective quantitative and qualitative performance, Differential Ion Mobility Technology has proven to be a valuable addition.
SelexION® DMS Technology Will Breakthrough Sensitivity BarriersSelexION DMS Technology, coupled with QTRAP or TripleTOF LC-MS systems, can separate analytes of identical mass, reduce chemical noise, and improve quantitative accuracy, to rapidly deliver the forensic data you need. You can benefit from high throughput methods with little or no sample preparation and minimal chromatographic retention.
DMS separates ions based on the difference between their ion mobility’s in a high and low electric field in gases at or near atmospheric pressure. SelexION is placed in front of the inlet of the mass spectrometer, and the ionized molecules travel into the orthogonal geometry shaped DMS cell. Ions are separated on mobility scale due to differences in molecular size and shape, thereby providing highly selective analysis with minimal background interferences.
Advantages of the planar DMS geometry include:
SelexION offers a unique approach to separation that is unmatched by any other available method. Download the e-book to find out how we achieved LOD of 0.05 ng/mL and LOQ of 0.5 ng/mL using SelexION technology in the analysis of methyldienolone in urine, which were otherwise 2 and 5 ng/mL respectively without.

For more than 20 years, the CDCO has supported academic, commercial, and not‑for‑profit drug discovery programs with deep expertise in pharmaceutical lead optimization. Within the bioanalytical group, their role is to enable rapid and reliable decision‑making through quantitative analysis of candidate drugs in biological matrices.
PFAS are increasingly at the center of regulatory change, scientific research, and industry discussion worldwide. As analytical capabilities improve and expectations around environmental responsibility continue to evolve, understanding the role PFAS play, and how they are being addressed, has never been more important. This blog provides an overview of what PFAS are, why they matter, and how responses from regulators and industry are changing.
Pesticides are widely used in agriculture to protect crops and maintain yield, but their presence in food must be carefully monitored. To safeguard consumers, regulatory authorities worldwide set maximum residue limits (MRLs), often at very low concentrations and across a wide range of compound classes.
