|Chromatography is a separation method to identify and separate different components in a sample mixture using different techniques. Researchers focus on the advances in separation science to make the purification of different substances easy and efficient. Scholarly peer review is the process of subjecting an author's scholarly work, research, or ideas to the scrutiny of others who are experts in the same field, before a paper describing this work is published in a journal. The work may be accepted, considered acceptable with revisions, or rejected. Peer review requires a community of experts in a given (narrowly defined) field, who are qualified and able to perform reasonably impartial review.
