“…A layer of MWCNTs was coated on the paper surface, which acted as an electrode to induce a stable electric field, which was expected to play a key role in the ionization of target analytes. The effect of atmospheric pressure chemical ionization is similar to carbon fiber PSI 53 and carbon fiber ionization 54 described earlier. Experimental results revealed that the fabrication of paper substrates by MWCNTs could lead to enhancement in signal intensities by 20–50 times and 2–4 times for PAHs and PFCs, respectively, compared to unmodified paper substrates (Figures S3–S5 [supporting information]).…”

“…The effect of atmospheric pressure chemical ionization is similar to carbon fiber PSI 53 and carbon fiber ionization 54 The recovery was evaluated by spiking blank samples with appropriate amounts of the analytes at three levels corresponding to LOQs, 10-fold LOQs, and 20-fold LOQs. The average recovery rates varied from 93.1% to 105.8%, with relative standard deviations (RSDs) of 3.5%-10.3% for six repeated measurements.…”

RationaleRapid on‐site detection of persistent organic pollutants (POP) is highly desirable for environmental protection.MethodsHerein, a rapid on‐site analytical workflow was developed for the investigation of polycyclic aromatic hydrocarbons and perfluorinated compounds using multiwalled carbon nanotube–modified paper spray ionization (PSI) coupled with a miniature ion trap mass spectrometer. Critical parameters regarding PSI and miniature mass spectrometry analysis were optimized.ResultsThe analytical performance of the developed method was evaluated under optimized conditions, obtaining a short analysis duration of less than 1 min, sufficient linearity with correlation coefficients greater than 0.99, acceptable recovery rates of 93.1%–105.8% with relative standard deviations of between 3.5% and 10.3%, and reasonable sensitivity with limits of detection and quantitation of 2–200 and 5–500 μg/L, respectively.ConclusionsConsidering these aspects, it was concluded that the present approach demonstrated a promising solution for rapid on‐site detection of emerging POPs.

The development of ambient ionization mass spectrometry (AIMS) has transformed analytical science, providing the means of performing rapid analysis of samples in their native state, both in and out of the laboratory. The capacity to eliminate sample preparation and pre‐MS separation techniques, leading to true real‐time analysis, has led to AIMS naturally gaining a broad interest across the scientific community. Since the introduction of the first AIMS techniques in the mid‐2000s, the field has exploded with dozens of novel ion sources, an array of intriguing applications, and an evident growing interest across diverse areas of study. As the field continues to surge forward each year, ambient ionization techniques are increasingly becoming commonplace in laboratories around the world. This annual review provides an overview of AIMS techniques and applications throughout 2022, with a specific focus on some of the major fields of research, including forensic science, disease diagnostics, pharmaceuticals and food sciences. New techniques and methods are introduced, demonstrating the unwavering drive of the analytical community to further advance this exciting field and push the boundaries of what analytical chemistry can achieve.

A novel inorganic nonmetallic material boron carbide (B4C) was applied in paper spray ionization to analyze organic molecules in both negative and positive modes. The utilization of B4C has led to a notable enhancement in signal responses for various molecules, including bisphenols and drugs, by approximately two to four times. The limit of detection (LOD) of bisphenol AF and nilotinib standard solutions can reach 1 and 0.5 μg/mL, respectively. Moreover, linear relationships for bisphenol AF was established within the concentration range of 1–100 μg/mL, exhibiting strong correlation coefficients. Recovery experiments for BPAF in water samples from the inlet and outlet of a sewage treatment plant, conducted without any pretreatment, achieved a maximum recovery rate of 98.8% and an RSD below 9.78%.
