WA***1 Atomic Absorption
Spectrometer
.Introduction
WA***1has high precision,
humanized designation to fully meet the different requirements of
users. Users can choose graphite furnace control, automatic
injector, hydride generator and so on.
.Features
1. There are four-lamps position and
six-lamps position for option, and the preheat lamp number can be
customized, which can short the waiting time of operating
process.
2. The lamps have the functions
of self-optimized, and three-dimensional self-adjustment to
maximize the energy.Â
3. The elements have the
functions of negative high-voltage self-memory, wavelength
scanning, lamps self-optimization and energy optimization with one
key step.Â
4. It is convenient for the
testing results to be exported by various formats and operated by
office software.Â
5. This system can be remote
controlled so that its problems can be solved in time with remote
control technique.
6. Hydride generator can be
used.
7. Automatic ignition system can be
used.
