Column Watch
This is our annual review of new liquid chromatography (LC) columns and accessories introduced at Pittcon and throughout the previous year.
Peer-Reviewed Articles
In this study, we describe a simple and rapid liquid chromatography–mass spectrometry (LC–MS) method for the evaluation of caffeine, taurine, and aspartame in teas, soft drinks, and energy drinks using high performance liquid chromatography (HPLC) coupled with electrospray ionization (ESI)-MS detection and multiple injections in a single experimental run (MISER) analysis.
The modern analytical laboratory generates enormous amounts of data. These data are typically stored in vendor-specific, proprietary file formats.

The Periodic Table of Ion Analysis app is designed as a reference of optimal methods for separating and detecting the most commonly determined ions on the periodic table
Perspectives in Modern HPLC
This installment highlights noteworthy high performance liquid chromatography (HPLC) and related products introduced at Pittcon 2015 in New Orleans, Louisiana, as well as in the year prior.
LC Troubleshooting
When converting methods from liquid chromatography (LC) to ultrahigh-pressure liquid chromatography (UHPLC), don't get confused by flow-rate settings.
The Essentials
Many of us use electron ionization (EI) in gas chromatography–mass spectrometry (GC–MS) without a good understanding of the technique and how we might manipulate the process to give more appropriate results or a better understanding of the analytes under investigation.
