Phoenix-986AA

The Phoenix-986AAS is an easy-to-use Atomic Absorption Spectrophotometer dedicated to the laboratories that are after practical operation rather than extravagant sophistication which may never be required to the extent of 70% sometimes. What we are offering here is a low-cost alternative where no efforts were spared to provide high precision and ease of use in a simple instrument which can fit in every budget.
Fitted with a motorised flame/furnace switchover at a press of a key, it uses a personal computer to control via a dedicated applications software the instrument and relevant accessories.
The automatic 8-lamp turret provides a multi-sequential AA analysis whereas eight different elements may be selected at one time with their respective measurement parameters and then loaded automatically in the respective order provided by the operator. The settings and adjustments of the instrument's conditions for measurement are completed automatically.
Two Background Correction modes are offered to the user's choice. The self-reversion mode that can be carried out over the entire wavelength range using the same light of a Hollow Cathode Lamp but with a different lamp current and the D2 Lamp Background Correction mode which is ideal for high sensitivity analyses.
An automatic temperature control is secured during graphite furnace measurements. Up to 9 heating steps are allowed with 3 choices of ramp, ladder and full-power heating. All signal and temperature curves may be stored for future re- call by the operator.
A complete data report of single-element or multi-element measurements is offered for display and print-out. The spectra of element lamps, standard curves, signal curves, operating parameters and operator's own-defined texts may be displayed and printed out upon demand.
