Performance of selected scintillation cocktails at various measurement times.

[CPM3]	1  min	2  min	10  min	60  min
ROTISZINT	13.49 ± 3.56 (±3.67)	12.49 ± 2.63 (± 2.50)	12.62 ± 1.14 (±1.12)	12.52 ± 0.49 (±0.45)
AquaLight+	12.92 ± 3.76 (±3.59)	11.82 ± 2.42 (±2.43)	12.97 ± 1.17 (±1.14)	13.32 ± 0.55 (±0.47)
Ultima Gold XR	10.31 ± 36.25 (±3.21)	8.03 ± 1.97 (±2.00)	7.80 ± 0.91 (±0.88)	7.90 ± 0.42 (±0.36)

Performance is presented by CPM3 (events counted by all three PMTs) of the counter background values and respective standard deviation. Values in parentheses are calculated values based on the Poisson distrubution. Except for the 1-min measurement of Ultima Gold XR, the calculated and measured values are in good agreement.
