Cryogen‐Aided Chromatographic Purification of Millimole Quantities of Methane for Spectroscopic Clumped Isotope Analysis

Rapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Quantum cascade laser absorption spectroscopy (QCLAS) is a fast and reliable method for analyzing the bulk (𝛿13C‐CH4, 𝛿D‐CH4) and clumped isotopic (∆13CH3D and ∆12CH2D2) composition of methane. However, precise measurements of ∆12CH2D2 require 0.5 to 1.8 mmol of purified methane (equivalent to 15 to 40 mL at STP).

A New Approach to the Analysis of Dissolved Gases Using Passive Samplers, With Portable Mass Spectrometry and Gas Chromatography Techniques

Rapid Communications in Mass Spectrometry, Volume 40, Issue 17, 15 September 2026.
ABSTRACT Rationale Portable mass spectrometry systems such as miniRUEDI enable rapid and low‐cost field analysis of dissolved gases with high temporal resolution. However, they remain poorly suited for discrete small‐volume water samples. This study presents an approach based on passive sampling for groundwater and surface waters dissolved gases and ...

Next‐Generation Water Treatment With Molybdenum Disulfide: Dual‐Functionality in Pollutant Adsorption and Photocatalysis

Advanced Materials Technologies, Volume 11, Issue 17, 3 September 2026.
ABSTRACT Molybdenum disulfide (MoS2) has attracted attention as a promising material due to the growing demand for environmentally friendly, cost‐effective, and efficient water treatment techniques. With its physicochemical characteristics, this stratified bidimensional material allows it to be highly effective in adsorption and catalytic performance ...

Assessing the within‐site variability and apparent reproducibility of soil organic carbon fractionation methods in subsoil

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Soil organic carbon (SOC) fractionation methods are widely used to assess different carbon (C) pools, but their reproducibility, particularly with depth, remains unclear. This study evaluated the within‐site variability of chemical and physical fractionation methods for SOC at 0‐ to 30‐cm and 30‐ to 60‐cm depths across four apple (Malus ...
