Shape. Their peak Grazoprevir medchemexpress concentration is around 70 ppb, reached after 19 min. This represents a difference of about 205 when it comes to peak concentration using the NBQX disodium medchemexpress preceding group of fluorometers. The curve shape shows a slower concentration increase on both fluorometers 14 and 15, and also a greater tailing effect on quantity 15. Fluorometers 14 and 15 show a strongly oscillating concentration on their tail. The tracer mass recovery rate, calculated by integrating concentration values over time and multiplying by the measured flowrateTheir peak concentration is about 9000 ppb, reached just after 16 min. Fluorometers 14 and 15 show various values for peak time and concentration plus a distinct curve shape. Their peak concentration is around 70 ppb, reached soon after 19 min. This represents a difference of around 205 when it comes to peak concentration with the earlier group of fluorometers. The curve shape shows a slower concentration improve on both fluorometers 14 Hydrology 2021, eight, 168 7 of 15 and 15, as well as a greater tailing effect on quantity 15. Fluorometers 14 and 15 show a strongly oscillating concentration on their tail. The tracer mass recovery price, calculated by integrating concentration values over time and multiplying by the measured flowrate (0.289 m3/s in the course of the injection), shows values around shows values about 79 , except for fluorometer 14, (0.289 m3 /s through the injection), 79 , except for fluorometer 14, which shows a value of 66 .shows a value of 66 . whichFigure four.
