Submission and preparation of manuscripts:

Manuscripts must be as original research papers (original article) and contain high-quality results with novelty in the field. Normally these will be based on analytical results and experiments. Preferably the manuscript should not have more than 20 double-line spaced manuscript pages, including tables and illustrations.

Submission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere in the same form, in English or in any other language, including electronically without the written consent of the copyright-holder.

Authors should submit their manuscripts online. Electronic submission substantially reduces the editorial processing and reviewing times and shortens overall publication times.

Manuscripts that are accepted for publication will be checked by our copyeditors for spelling and formal style. This may not be sufficient if English is not your native language and substantial editing would be required. In that case, you may want to have your manuscript edited by a native speaker prior to submission. A clear and concise language will help editors and reviewers concentrate on the scientific content of your paper and thus smooth the peer review process.

Cover Letter:

During submission of the article, a cover letter should be included having authors full address and telephone/fax number. The  corresponding author should state that the   manuscript has not been published elsewhere or considered for publication by any other  journal.
