Scope
Aims, scope and focus
Microchemical Journal is published by Elsevier Inc. and is in Zone 2 of Chemistry in the CAS Journal Ranking (2025 upgraded edition). By OpenAlex counts of its recent articles, its largest topics are Analytical chemistry methods development, Electrochemical sensors and biosensors and Advanced biosensing and bioanalysis techniques, together about 32% of its articles. (generated from OpenAlex topic counts and CAS ranking data)
Microchemical Journal is a rigorous, yet supportive peer-reviewed journal covering all aspects and phases of Analytical Chemistry, including sampling, sample pre-treatment, measurement and data analysis. The Microchemical Journal publishes articles which are at the forefront of modern analytical chemistry and cover innovations in the techniques to the finest possible limits. This includes Fundamental Aspects, Instrumentation, Mass Spectrometry, Chromatography and Electrophoresis Separations, Microscale and Nanoscale Systems, Omics (Proteomics and Metabolomics), Sensors and Sensing (Single-molecule sensors, Microfluidic systems, Biosensors), Chemometrics, Machine Learning, Artificial Intelligence and Imaging, and original applications concerning clinical, environmental, industrial, food, forensic, and heritage fields.Electroanalytical and optical sensors, separation methods, spectroscopy, electroanalytical methods and all new procedures for inorganic, organic, biochemical molecules and micro-organisms detection and quantification are welcome. However, manuscripts must provide significant improvements and novelty compared to the established methods.The journal does not consider routine analytical method applications in such areas as classical and new materials characterization, pharmaceutical, model environmental pollutant (e.g. dye and antibiotic detection and degradation), and industrial quality control. Routine, incremental studies without innovative analytical chemical methodologies (e.g. different reagents but no new analytical approaches or detection problems), superficial analytical chemistry discussions and analyses, and fragmentation of work are strongly discouraged. In any case, applications to real sample analysis instead of the use of spiked ones are preferred. The journal was established in the late 1950s as a medium devoted to the developing field of microchemistry. As the area of microchemistry has moved into analyses in microgram masses and micro volumes (and lower), low detection limits, and sophisticated and compact instrumentation, the Microchemical Journal has continued to evolve and change with this growing and expanding area, covering nowadays analytical chemical research in its broadest sense, including micro-organisms identification and quantification, miniaturization, automation, the use of nanomaterials and smart materials-based methodologies for sample preparation and analyte determination, and application of AI-based, deep/machine learning chemometrics in its broadest sense, considering also those regarding -omics studies, big data, artificial intelligence and hyperspectral imaging.The journal will publish special issues devoted to hot topics, inviting the most productive and active researchers. Besides full research articles, Critical Review papers, Short Communications, Tutorials and Technical Notes are also considered.
