The Diffusive Gradients in Thin Films (DGT) technique has become the most widely used passive sampling method for inorganic compounds. This widespread adoption can be partly attributed to the development of new binding phases that facilitate the sampling of numerous analytes. In contrast, to date, the DGT sampler for inorganic compounds has not seen any significant design improvements. In this manuscript, a new design for the DGT sampler is proposed. The new design, referred to as the Double-Faced DGT (df-DGT) sampler, features dual sampling windows, enabling a twofold increase in analyte mass uptake compared to the conventional DGT sampler.

薄膜采样器中的双面扩散梯度 (df-DGT):为水部署提出了一种改进的 DGT 采样器设计



薄膜扩散梯度 (DGT) 技术已成为无机化合物使用最广泛的被动采样方法。这种广泛采用部分归因于新结合相的发展,这些固定相有助于对多种分析物进行采样。相比之下,迄今为止,用于无机化合物的 DGT 采样器尚未看到任何显著的设计改进。在本手稿中,提出了 DGT 采样器的新设计。这种新设计被称为双面 DGT (df-DGT) 进样器,具有双采样窗口,与传统的 DGT 进样器相比,分析物质量吸收增加了两倍。
