Although sample sizes for Bobolinks (n = 15) and Chimney Swifts (n = 12) were limited, there was relatively little variation in the retention times within each species, as all the Chimney Swifts retained transmitters long enough for adequate short-term study yet none of the Bobolinks did.
Retention time and storage period had higher effects on performance of WSB-based MDF, especially on static bending (MOR and MOE) and SH, than on performance of DSB-based MDF.
Retention time and percentage of variant haemoglobin can provide important clues in differentiating variant haemoglobins eluting in the same window.
In summary, the relationship between the retention time value for a given compound and its Log D property provides a means for measuring both the analytical range and the resolution capability of a given chromatographic method, in which analyte separation is primarily dependent upon the hydrophilic/hydrophobic interaction between the mobile and stationary phases of the HPLC column.
In the chromatogram we found a peak with retention time 12.
Access frequency--The frequency of access to records typically diminishes through time, and identifying periods of high access versus those periods when records are rarely referred to will help in determining active (onsite) and inactive (offsite) retention time periods.
The mill is also installing a new headbox on PM 62 and is rebuilding the continuous digester to get better plug flow and increased retention time.
The retention time (time required for manure staying in the TCC processor to allow oil conversion) was reduced to about 20 minutes.
72 based on a retention time of dibutyl phthalate and peaks detected at a relative retention ratio in the range of 1.
