truffa opzioni binarie The FMA-80 detects mercury contents in solutions by atomic fluorescence (AFS).
This technique differs from the more conventional AAS technique in that it is more sensitive, more selective, and is linear over a wide range of concentrations.
However, any molecular species present in the carrier gas will quench the fluorescence signal and for this reason, the AFS technique is most commonly used with an inert carrier gas such as argon.
AFS has better linearity and more stable baseline than AAS.
AAS instead works better for more complex matrices, as it suffers less from interferences.
The FMA-80 is a very flexible working platform as it can be chosen in different configurations: AFS only or combination of AFS and AAS, depending on your application.
The terminal runs Milestone’s unique EasyCONTROL software, providing simple and intuitive, but extremely flexible and powerful control over the analytical process.
All sample parameters, including furnace temperatures, method profiles, absorbance signals, results, and calibrations are saved.
They can be viewed, easily transferred using a USB memory stick or integrated to LIMS.
EasyCONTROL software includes the unique AutoBLANK feature. If, following the analysis of a sample with very high mercury contents, the pre-set blank level is exceeded; EasyCONTROL will automatically run blank cycles until the pre-set blank level is achieved.
EasyCONTROL allows the operator to designate certain samples as reference, or QC samples.
Once a sample is designated as a reference, a known concentration value is entered.
If the analysis of that sample yields a concentration outside the acceptable range specified by the operator, EasyCONTROL can be pre-set to either continue, stop, or pause the analysis of the remaining samples.
