Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

Mass Spectrometry Reviews, Volume 45, Issue 3, Page 548-582, May/June 2026.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Effective Removal of Fe and Ca From Coal Fly Ash for High‐Purity and High‐Surface‐Area Zeolite X Synthesis: A Comparative Study of Acid Refluxing and Acid Roasting Methods

ChemistryOpen, Volume 15, Issue 5, May 2026.
Coal fly ash (CFA) is an abundant industrial waste rich in silica and alumina and represents a viable feedstock for zeolite synthesis; however, high levels of calcium and iron limit zeolite purity and crystallisation. This study evaluates acid refluxing and acid roasting as pre‐treatment strategies for the simultaneous removal of Ca and Fe from high ...

Thermodynamic Insights Into Direct Methane to Methanol Conversion Using O2 and CO2 Oxidants

ChemistryOpen, Volume 15, Issue 5, May 2026.
A thermodynamic analysis compares O2 and CO2 for the direct partial oxidation of methane to methanol. While O2 offers higher theoretical conversions, it poses safety risks and favors total oxidation. CO2 presents a safer, more sustainable alternative despite its thermodynamic limitations.
