LC Method Scaling, Part II: Gradient Separations
John W. Dolan
If scaling isocratic separations is so simple, why is gradient scaling so confusing? |

Sensitive, Ultrafast GC/MS/MS
The only GC/MS/MS capable of running all triple quad operational modes, without sacrificing sensitivity or accuracy, Shimadzu’s GCMS-TQ8030 elevates this method to a new level of performance. It features a true scan speed of 20,000 u/second and 600 MRM transitions/second. In addition, high-sensitivity ion optics eliminate neutral noise and maximize signal intensity for ultimate S/N ratio.

Waters introduces the ACQUITY QDa Detector
The future is now separated from the past. Imagine a lab where all analytical scientists
can acquire high-quality mass spectral data. On their own. Within their existing workflows. Across every sample. Without training. Waters imagined just that and introduces the ACQUITY QDa Detector.

Analysis of Amphetamines and Synthetic Cathinones in Hair Samples Using LC–Tandem Mass Spectrometry and Solid-Phase Extraction
Albert A. Elian, Jeffery Hackett, and Kerrie T. Donovan
An efficient method for forensic analysis of amphetamines and synthetic cathinones — the illicit drugs often called "bathsalts" — in hair samples |
Application of Pyrolysis–Gas Chromatography–Mass Spectrometry for the Identification of Polymeric Materials
Peter Kusch, Gerd Knupp, Wolfgang Fink, Dorothee Schroeder-Obst, Volker Obst, and Johannes Steinhaus
This pyrolysis–GC–MS method enables direct analysis of solid or liquid polymers without sample pretreatment, as illustrated here for various materials, including a dental filling material and a car wrapping foil. |
