KEY FEATURES

Configurable magnetic field from 0.6 to 1.1 Tesla. This allows better sensitivity by adjusting the magnetic field to suit the element. Field strength can range from 0.6 to 1.1 Tesla.

Automated 8 lamp turret for simplified multi-element analysis.

Self aligning furnace tubes for easy change-out.

Electronic Sample Viewing (ESV) camera allows easy visual observation of sample injection. The ESV also allows viewing of the critical heat ramp up to 120 Deg C to ensure even slow heat-up without steam bubbles forming.

Electronic positioning of probe for correct deposition of sample drop.

Selectable standards presentation with:

1. Insertion of external made up standards

2. Autosampler preparation of required stanadard concentrations from stock stanadard solution.

Gold plated furnace contacts for reproducable furnace firing conditions.

Transversely heated pyrolytically coated graphite tubes.

MEASURES

Various metals at PPB/PPT levels or alternatively as characteristic mass.

Ideal for low level metals in difficult matrices such as blood,urine,brine,soil etc.
