Mass spectrometric techniques are typically divided into two distinct fields: atomic and molecular. Liquid sampling – atmospheric pressure glow discharge (LS-APGD) has been developed as a versatile ionization source capable of combined atomic and molecular (CAM) analysis. To date, the LS-APGD has demonstrated impressive results in U isotope ratio analysis as well as molecular analysis across a wide range of instrument platforms.1-3 While molecular sampling has been demonstrated on this source, these samples fall into the realm of ESI-type samples, larger, polar compounds, most commonly LC-relevant drug targets. Presented here will be the demonstration of the wider versatility of the LS-APGD as a CAM ionization source using the Advion expression Compact Mass Spectrometer (CMS).

Comprehensive Reaction Monitoring & Flow Chemistry Resources

Did I make my compound?”

 

It’s a common phrase that may follow you around the lab daily. With time-sensitive reactions coupled with the time-sensitive need to confirm data, fast reaction monitoring is essential for bench chemists looking for the most streamlined daily workflow.

The expression Compact Mass Spectrometer (CMS) addresses the need of organic and synthetic chemists to understand the optimal time to quench a reaction mixture. They can obtain answers within minutes rather than hours or days. Additionally, multiple inlet techniques like the atmospheric samples analysis probe (ASAP), Plate Express TLC plate reader, direct injection and more provides the ultimate in flexibility for sample analysis without the need for complex sample preparation. In addition, the use of the expression CMS in flow chemistry applications is an ideal reaction monitoring tool.
