Identification of plasticizers using thermal desorption dielectric barrier discharge ionization mass spectrometry
Lu, Qiao; Guan, Xiaokang; You, Xue; et al. (2025)

Plasticizers, which are extensively utilized in the manufacturing of plastic products, have garnered significant attention due to their potential toxicity and the consequent health and environmental risks they pose. Traditional methods for detecting plasticizers, such as gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS), are often time-consuming and require complex sample preparation. In response to these challenges, this study introduces an innovative approach for the rapid and sensitive identification of seven common plasticizers using thermal desorption dielectric barrier discharge ionization mass spectrometry (TD-DBDI-MS). The proposed technique significantly reduces background interference by employing nitrogen as the discharge gas, thereby enabling the detection of characteristic quasi-molecular ions ([M + H]$^+$) and their fragments, which are crucial for structural elucidation. The method exhibits remarkable sensitivity, with a limit of detection as low as 0.1 ppm for diethyl phthalate and a linear dynamic range of orders of magnitude. Furthermore, it allows for expedited screening of various plastic products, including cling wrap, packaging bags, and centrifuge tubes, with each sample analyzed in less than 30 seconds. This study underscores the efficacy of TD-DBDI-MS as a rapid, sensitive, and user-friendly methodology for the preliminary screening of plasticizers in a wide range of materials.

Quantifying cyanide in water and foodstuﬀ using corrin-based CyanoKit technologies and a smartphone
Cherbuin, Mathias; Zelder, Felix; Karlen, Walter Christian (2019)
The Analyst
This paper describes the detection of endogenous cyanide using corrin-based CyanoKit technologies in combination with a smart-phone readout device. When applied to the detection of cyanide in water, this method demonstrates high repeatability and discrimina-tive power with a limit of blank of 0.074 ppm and an instrument limit of detection of 0.13 ppm. Quantiﬁcation of endogenous cyanide in cassava and bitter almond extracts with the smartphone readout is in excellent agreement with independent analyses using traditional spectrophotometric detection. The prototype system objectively detects levels of cyanide with a high granularity at the point-of-need and does not depend on large, heavy and expensive instrumentation. The methodology has the potential to be easily adopted in resource limited situations and low-income countries.
