Automatic data collection. The least squares principle automatically fits the working curve.
Automatic two-point or single point standardization of analysis curves
Automatic sample control calibration, one analysis curve, can choose multi-point sample control calibration.
Output methods available: intensity, intensity ratio, concentration, correction concentration
At the same point, it is possible to repeat one or more excitations, and delete the results of one or more excitations
Automatically calculate the average value,SD and RSD
Correction of interference between elements and background correction
Common standard substance library
The test results can be printed out and saved in a disk. The printing format can be arranged by oneself. It can also be generatedWord documents, etc. Save it.
The test results can be transmitted over long distances through networks and computer standard ports.
The software comes with fault diagnosis and self-test programs. The automatically generated data file can be used to remotely diagnose instrument malfunctions.
