ZEEnit 700 P atomic absorption spectrometer

ZEEnit series atomic absorption spectrometers with Zeeman background correction

ZEEnit 700 P are atomic absorption spectrometers with flame and electrothermal atomization in graphite furnace and Zeeman background correction. ZEEnit series atomic absorption spectrometers combine abilities to function in dual-field and triple-field baseline correction mode with high sensitivity and wide dynamic range. Sample change parameters are optimized by altering the magnetic field strength accurate to 0.05 T. The maximum magnetic field value reaches 1 T, which enables to obtain high sensitivity in defining the elements with low magnetic sensitivity value.

Main advantages:

analysis of hard-melting elements already at atomization temperature of 2600°C;
a pyrometer for non-contact accurate online measurement of temperature;
monitoring of dosing and atomization processes in the furnace with the aid of a video camera;
quantitative evaporation of sample throughout the tube length;
no condensation on the furnace ends;
uniform temperature distribution along the furnace axis;
transverse heated graphite furnaces and current supply via integral contacts;
carousel 8-position rotating vertical turret;
reduced matrix interferences and memory effects;
automatic dosed introduction of samples into the flame with the smart dilution feature;
continuous batch-wise injection of microsamples into the flame using a segmented flow star (SFS).
