Abstract：A concise, factual, and detailed abstract of 200–300 words is required for all manuscripts. This should state the research purpose, main methods, principal results, and major conclusions. Avoid the use of abbreviations in abstracts.
Key words：List five to eight key words that best describe the nature of the research, avoiding abbreviations, and molecular formula. The first letter of each key word is not capitalized. Separate the key words by semicolons. These key words will be used for indexing purposes.

The introduction (untitled) states the background of the study, its relation to previous work in the field, the questions to be answered, and the methods adopted, to allow readers to understand and evaluate the results of the present work. Relevant previous work by the same authors should be referenced.
Provide sufficient detail to enable others to repeat the experiments. Methods already published should be indicated by a reference, but new and modified experimental procedures should be described in detail.
1.1 Apparatus and chemicals
1.2 Chromatographic procedure
2 Results and discussion
The results should be given clearly and concisely, and the discussion should explore the significance of the results of the work. Give results in a logical sequence in the text, tables, and illustrations. Do not repeat in the text all the data in the tables or illustrations.
2.1 Figures and tables
All figures and tables must be referenced in the text and placed in the text near the point of the first mention. Number them consecutively with Arabic numerals. The captions should be understandable without reference to the text. The same data should not be presented in more than one figure or in both a figure and a table. Tables should be created using the table format feature of the MS Word software, and authors should ensure that each data entry is in its own table cell. In the initial manuscript submission, the figures and tables must be of sufficient quality for peer review. If the manuscript is accepted, all figures and tables, and their titles and legends will be re-created or edited according to the Journal style prior to publication. Authors will be asked to provide proper figures (including experimental data) by the production staff. For printing, the minimum resolution for a black and white line art, grayscale art, and color art is 1200, 600, and 300 dpi, respectively.
2.2 Units of measurements, symbols and abbreviations
All measurements should be expressed in the international system of units (SI). Other quantities should be converted into SI units. Italicize symbols of physical quantities, but not their units. Leave a single space between the number and the unit of a value. Each abbreviation must be defined the first time it is used in the abstract and again in the body of the manuscript.
For Articles and Reviews, a conclusion that briefly summarizes the principal conclusions of the work is necessary. The conclusion is an extension of the results and discussion, but not a simple repetition. It is also different from the abstract. No more than one paragraph is recommended.
When a large number of field-specific terms are used in the manuscript, list their definitions in this section.
Technical assistance, material support, and other help or advice may be acknowledged briefly in this section (excluding financial support, which should appear in the footnote on the title page).
Number references in the order they appear in the text. Ensure that each reference cited in the text is present in the reference list (and vice versa). Numerals for the references in the text are given in square brackets [ ]. Each reference should be separately numerically numbered, without the use of alphabetical suffixes. Personal communications, unpublished materials, and works that have not yet been accepted for publication are not recommended as references. In the reference list, periodicals, books and patents should be cited in accordance with the following examples:
