求助，翻译一段英文
When pesticides are well resolved from one another and from nonpesticide artifacts co-extracted from the sample substrate，there will be the greatest chance for the analyte and the co-injected standard to separate if they are not the same compound。If the HPLC system has recycling capability，the co-injected mixture can be recycled several times to try to separate the analyte from the added standard.
