Special Issue Information

Dear Colleagues,

Mass spectroscopy is an analysis technology that enables the detection of high sensitivity to mass via the ionization, acceleration, separation, and detection of samples. Mass spectroscopy technologies such as LC-MS, GC-MS, MALDI-TOF MS, and tandem mass spectroscopy have been developed for various fields, including molecular structural analysis, quality control for industrial products, environmental monitoring, drug analysis, and biological analysis. Mass spectroscopy, which can provide rapid analysis, small-volume analysis, and sensitive analysis, has already been accepted as an advanced tool in analytical chemistry and exhibits the potential to grow as a novel diagnostic paradigm in the biomedical field.

This Special Issue aims to provide an overview of recent advances in mass spectroscopy in analytical and bioanalytical chemistry. We therefore welcome the submission of articles whose scope includes, but is not limited to, sample pretreatment methods, novel chromatography approaches, and novel mass spectrometric techniques. In addition to the subject areas outlined in the keywords below, we welcome all studies that perform analytical and bioanalytical analysis using mass spectroscopy. Both review articles and original research papers will be considered for publication.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Chemosensors is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The simultaneous determination of arsenic and mercury species in human urine is critical for clinical diagnostics and therapeutic monitoring because it reduces the costs, time, and consumption of samples. This study proposes a method of utilizing high-performance liquid chromatography-inductively coupled plasma mass spectrometry (HPLC-ICP-MS) for the concurrent analysis of arsenic and mercury species in urine samples. The separation was performed using a Hepu AR 5 μm C18 (250 × 4.6 mm) column, employing a mobile phase composed of 0.1% L-cysteine, 5 mM NH4H2PO4, and 4 mM tetrabutylammonium hydroxide (TBAH). The samples were diluted with water, and matrix interference was reduced through the application of a kinetic energy discrimination (KED) mode. Calibration curves for four arsenic species and three mercury species exhibited strong linearity within the range of 1–20 μg L−1, with correlation coefficients (r) above 0.999. The limits of detection (LOD) ranged from 0.030 to 0.086 μg L−1, while the limits of quantitation (LOQ) were observed to range from 0.10 to 0.29 μg L−1. The spiking recoveries for all species varied from 87.0% to 110.3%, and the intra-day and inter-day relative standard deviations (RSD) were determined to be 1.1–6.0%, and 0.8–9.2%, respectively. These results indicate that the developed method achieves high precision, accuracy, and suitability for clinical applications, offering valuable insights for the diagnosis and treatment of heavy metal exposure.
