Excellent sensitivity
The new optical system and the improved graphite furnace power supply circuit ensure high sensitivities. Using an ordinary hollow cathode lamp, the Z-5000 Series spectrophotometer is capable of analyzing As, Se and Sb in tap water and environmental water, which previously have only been measurable using an EDL high-intensity lamp in a conventional graphite furnace analyses.
Versatile multi-tasking functions available through friendly user interface.
Powerful accuracy control functions are incorporated.
Windows(R)-compatible software is installed. Two atomic absorption applications can be run simultaneously, during measurement, an other analytical data processing can be carried out. In addition, a random-access autosampler function and other convenient functions can easily be used.
Calibration curve, sample check, standard check and other QC functions are provided to further significantly enhance data reliability.
Reduced space for installation, yet retaining the tandem.
The required installation space is reduced to approx. 70% of that for the conventional model, owing to the 3D arrangement of the optical system, compact design of the gas control unit and integration of the graphite power supply.
Model Z-5700 can be expanded to tandem type by installing an additional unit. The required space remains the same even after this additional installation.
