Figure 2
Cumulative assessment of all injection protocols showed clearly lower variations of the true injection time with regularly fitted PS-injectors (left section, separated by vertical blue dotted line) compared to RP-injectors (middle section, between vertical blue and red dotted lines). Experimental attachment of a high volume line to a PS- and a low volume one to a RP-injector (right section, separated by vertical red dotted line) led to deterioration of the performance of both injector types (both not significant; horizontal brackets indicate injector ties).
