Length of time sewage effluent is retained in the septic tank.
Period of time from the injection of the sample into the gas chromatography system until the point of maximum detector response for each substance.
Describing the time between sample injection and the appearance of a given solute's eluted peak maximum, retention time is adjusted to account for a column's void volume.
The time it takes water to fall from distribution pan to the basin or sump; the time evaporation takes place. In Sewage Treatment - the time retained in a system in which degradation, settling, digestion Or other actions can take place.
The time between injection and the appearance of the peak maximum. The adjusted retention time tR’ adjusts for the column void volume.
(turnover rate or flushing rate) The average length of time water resides in a lake, ranging from several days in small impoundments to many years in large seepage lakes. Retention time is important in determining the impact of nutrient inputs. Long retention times result in recycling and greater nutrient retention in most lakes. Calculate retention time by dividing the volume of water passing through the lake per year by the lake volume.
The time between sample injection (time zero) and the appearance of the band maximum; when all conditions are held constant, the retention time for a given band (or compound) remains constant.
