AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

Peak compression occurred when a sample solution was injected into a liquid chromatographic column. Another compression phenomenon took place at the interface of the two mobile phases with different solvent strengths under a gradient elution. We examined both effects using a whole-column detection (WCD) system which enabled direct observations of both the spatial and temporal peak profiles during the elution.
　　The sample peak width at the column inlet was highly related to the retention factor k. The peak standard deviation on the spatial coordinate was linearly proportional to 1/(1+k) at the column position ~1 cm. The peak width might stay narrower at the column outlet for a chromatographic run of a large k compared with a run of a small k with the use of a column with good efficiency. However, the peak width of a large k might become wider at the column outlet with the use of a low-efficiency column. The plate number increase of the continuous gradient prevailed over that of the stage-wise gradient. Plate numbers for gradient elutions were calculated in this study based on analyte moving rates. The results gave significant improvements, up to four folds in some experiments, compared with the use of conventional equations.
