Sherwood Scientific's Model 420 and Model 425 flame photometers can perform sample analyses outside the linear response range thanks to the inclusion of 420 Bluenotes software.
Now supplied free with all new Model 420 and 425 instruments, the 420 Bluenotes package increases the utility of these dual-channel flame photometers and facilitates measurement of all elements simultaneously.
The linear response range of the standalone instrument is extended to multipoint calibration with 420 Bluenotes, 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 will be able to measure all elements simultaneously via the host computer's on-screen, real-time display.
Jon Copsey, Sherwood Scientific's marketing manager, said: 'We have also updated the firmware of both the 420 and 425 for enhanced performance, adding a Clinical 102 Mode, which measures Na, K and Li but is designed for the expected higher concentrations of potassium in urine.
'The 420 Bluenotes disk includes a demonstration of how the software works with the instrument, helping users gain maximum benefit from the new functionalities,' he added.
The 420 Bluenotes package allows the operator to choose K or Li as an internal standard reference element.
The 'Spot Check' facility updates a previous multi-point calibration, thus adjusting for any drift (when the internal standard facility is not in use) and allowing previously generated calibrations to be re-used.
The software requires a PC running Windows XP or later and is fully compatible with combinations of newly supplied dual-channel flame photometer, diluter and auto sampler.
However, the new software is not backward compatible with units already installed.
