In an investigation of the Bundesanstalt für Materialforschung und prüfung (BAM) in Berlin, Germany, Spetec has tested two different peristaltic pumps and the “Easy Click” pump (a peristaltic pump with "Easy Click" connector) operated on a simultaneously measuring ICP-OES instrument. The goal was to see whether or not any difference of the analytical figures of merit can be observed. This investigation had demonstrated that all analytical figures of merit including limits of detection (LOD) and signal stability of in total ten elements (Al, Bi, Co, Cr, Cu, Fe, Mg, Mn, Ni, Se) from a standard solution do not differ significantly for all tested pumps. The resulting LODs measured are in the lower µg/L range and standard deviations of less than 1 % for eight and less than 2 % for the remaining two elements have been achieved.
As a result, Spetec can say that the “Easy Click” pump can compete with the two reference pumps concerning the analytical figures of merit but excels with easy and fast changing of tubing without any further adjustment. The “Easy Click” principle refers to the fact that the pressure of the plate is already adjusted by a spring, so that no manual optimization is needed any more, and the analysis sequence can be started immediately.
