Acetyl fentanyl overdose deaths have recently been confirmed in Pennsylvania. If states observe clusters or increases in illicit opioid-related overdoses above expected levels, acetyl fentanyl could be involved. CDC encourages laboratories to use an ELISA test to screen specimens from suspected illicit, nonpharmaceutical opioid overdose deaths. If an ELISA test is positive for fentanyl, CDC recommends confirmatory testing by GCMS.

A multitude of performance factors including dense gas CO2, small particle columns and mass spectrometry with UV detection are speeding up chiral separation methods development. Chirality plays a critical role in drug efficacy because enantiomers may have vastly different biological, pharmacological and toxicological properties.
Concurrent solvent recondensation–large volume splitless injection meets the EPA’s low detection limits for water analysis, while also reducing sample preparation time by more than one hour. This injection method produces a pressure surge from the vaporizing solvent, forcing the analytes onto the pre-column.
Agilent Technologies’ 2013 Essential Chromatography and Spectroscopy Catalog is divided into five sections to help the reader easily navigate the company’s growing portfolio, which includes general chromatography, sample preparation, GC and GCMS, LC and LCMS and spectroscopy.

The latest advancements in time-of-flight mass spectrometry have allowed the technology to easily tackle day-to-day analysis of complex samples by GC. On the face of it, time-of-flight mass spectrometry (TOF-MS) ought to be more popular than it is.
The need for good gas hygiene is important to avoid risking the integrity of instruments, as well as to produce better, more productive chromatography. Ensuring gas hygiene is one of the most important steps researchers can take to optimize the performance of GC or ICP systems. Impure gases can cause installation delays, premature instrument failure and flawed results.
NASA's Curiosity rover has a compact GC system for analyzing rocks, while new GC systems on earth work with increased sensitivity and accuracy.
