What are the components of productivity in an automated ion analyzer and what productivity innovations will the FS 3100 provide to my laboratory?
Productivity is defined as the number of reportable analytical results generated within a given period of time. Over the years there has been much argument over the relative productivities of FIA and SFA. While FIA can process a higher number of samples per hour than SFA with excellent inter-sample washout, the trade-off is a more limited dynamic range, a higher detection limit, and increased reagent consumption for higher throughput chemistries. Thus, an FIA chemistry must be slowed if operating greater than 2 orders of magnitude in analyte concentration within a run if baseline resolution (complete inter-sample washout) is to be maintained. FIA sample throughput also must be decreased to provide longer reaction times for lower detection limit work. In contrast, SFA combined with OI’s unique Expanded Range™ Detectors enables up to 4 orders of magnitude of dynamic range to be achieved within a single run. The limited dispersion of SFA allows a relatively narrow peak width or baseline-t
