31. Inclined angle of plates allows for increased loading rate / throughput and decreased retention time relative to conventional clarifiers. 32. The retention time of these simple devices are on the order of days after write-read-erase cycles have been demonstrated. 33. Further, the tolerance for this reaction to short retention times make this process ideal for carrying out industrial roasting. 34. Substituting in kT / F in place of l illustrates the retention time with respect to the cross force applied. 35. This should allow the retention time of any such species under the analytical parameters of the assay to be determined. 36. An increase in counter ion ( with respect to the functional groups in resins ) concentration reduces the retention time . 37. The internal standard selected should be again similar to the analyte and have a similar retention time and similar derivitization. 38. This causes each compound to elute at a different time, known as the " retention time " of the compound. 39. The retention index of a certain chemical compound is its retention time normalised to the retention times of adjacently eluting n-alkanes. 40. The retention index of a certain chemical compound is its retention time normalised to the retention times of adjacently eluting n-alkanes.
