Sherwood Scientific’s Model 420 and Model 425 dual-channel
flame photometers now are supplied with free 420 BlueNotes software. This product
launch enables the instruments to perform sample analyses outside the linear response
range and facilitates measurement of all elements simultaneously. The software package
increases the utility of these dual-channel flame photometers. The linear response
range of the stand-alone instruments is extended to multipoint calibration, enabling
analysis of a much wider range of sample concentrations. Another major change is
that all elements – Na, K, Li for Model 420 and Na, K, Li, Ca for Model 425
– can be measured at the same time, rather than only two at once. If required,
the operator can measure all elements simultaneously via the host computer’s
on-screen, real-time display.
