Experience has shown that once more than three simultaneous chemistries are attempted the time involved in verifying and maintaining reagents, flow rates, pump tubes, etc. outweighs the time gained by analyzing all the analytes at once. Since the FS3100 was specifically designed with rapid changeover in mind it is actually faster to run one or two chemistries. While these chemistries are running, reagents and samples for the next tests can be prepared. The multitasking software allows sample tables for the next runs to be created while data is being collected further speeding the process. Also, keep in mind that all that is required to change from one method to the next is changing a cartridge and an interference filter.
