Description

Description générale

With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" as well as "isocratic grade". This enables to minimize the gradient effect of the solvent involved.

Application

• Cross-Polarization Solid-State NMR Quantification of Species within Pores of Metal-Organic Frameworks: Though not directly linked to 1,4-dioxane, this study employs methodologies that could be applicable for the analysis of dioxane and other similar molecules within complex structures, relevant for chemists and material scientists engaged in molecular characterization (Wu & Xu, 2024).


• Photosensitized covalent organic framework as a light-induced oxidase mimic for colorimetric detection of uric acid: This innovative approach using a framework that could potentially be adapted for 1,4-dioxane detection underscores the intersection of material science and analytical chemistry, which could intrigue researchers developing new analytical methods (Wang et al., 2024).
