11. Retention time can be used to identify analytes if the method conditions are constant.12. The retention time from Lake Itasca to the Gulf is typically about 90 days. 13. Additional pre-treatment can be used to reduce the necessary retention time to produce biogas. 14. The high-k material was expected to yield longer retention times than the aluminum oxide structure. 15. The retention time measured under particular conditions is an identifying characteristic of a given analyte. 16. The lake's mean hydraulic retention time is 312 days. 17. Low temperatures can increase the data retention time of SRAM to many seconds or even minutes. 18. Experimentally, the electroosmotic mobility can be determined by measuring the retention time of a neutral analyte. 19. Temporary records at WNRC are either retained for a fee or destroyed after retention times has elapsed. 20. It's important to understand that retention time varies between different newsgroups within the text and binary categories.
