SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

The Microchemical Journal is a peer reviewed journal devoted to all aspects and phases of analytical chemistry and chemical 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, new developments, innovative and novel methods and applications including environmental and clinical field.
Traditional classical analytical methods such as spectrophotometry and titrimetry as well as established instrumentation methods such as flame and graphite furnace atomic absorption spectrometry, gas chromatography, and modified glassy or carbon electrode electrochemical methods will be considered, provided they show significant improvements and novelty compared to the established methods.
The journal does not consider routine analytical method development in such areas as pharmaceutical samples, chromatography, minor incremental changes such as sample preparation and pre-concentration for electrochemical, chromatography and spectrochemical methods. Methods considered will not be waters or situations where the methods cannot determine the molecules or metals of interest in real samples and depends on spikes, or simply using standard chemometric methods. Fragmentation of work is strongly discouraged.
The journal was established in the late 1950's as a journal devoted to the rapidly developing field of microchemistry. As the area of microchemistry has evolved into analyses in microgram masses and microvolumes (and lower), lower detection limits, and more sophisticated and compact instrumentation, the Microchemical Journal has continued to evolve and change with this growing and expanding area, covering now analytical chemical research in its broadest sense. The journal has published numerous special issues devoted to topics and well as selected conferences. The journal also considers original reviews.
