Abstract
Dissolved organic matter (DOM) reference materials are critical to ensuring reliable comparability of measurements across experiments and between labs. TRM-0522, isolated in 2022 from 45 m deep seawater off of Sweden’s west coast, fills the niche of a previously unavailable coastal marine DOM reference material. After its isolation, we detailed a limited number of metrics for TRM-0522, initially disclosing Orbitrap high-resolution mass spectrometry, nuclear magnetic resonance, carbon proportion, absorbance, and fluorescence data. With TRM-0522 becoming more widely used, a variety of labs have generated different metrics that help to characterize and define the chemical properties of this coastal reference material. Here, we disclose TRM-0522 data from elemental analysis, isotopic analysis (δ13C and Δ14C signatures), condensed aromatic “black” carbon characterization, ultra-HRMS (10-21 Tesla FT-ICR-MS and Orbitrap Fusion Lumos), CD3 labelling, and contribution of carbonyls in absorbance and fluorescence after NaBH4 reduction, pH titration, and nitroxide quenching. This greatly expanded dataset reinforces TRM-0522’s suitability as a coastal reference material, and provides metrics for future use between labs and for inevitable additional large-scale collections of material from this site.
