◆ Knowledge
Introduction |
| |
|
Laser induced breakdown
spectroscopy technology
with its advantage of
rapid and uncomplicated
operation is widely used
in many fields about
element identification.
The students can
understand the procedure
of laser induced plasma
generation by observing
the mechanism of action
between laser and
substance, searching
laser induced breakdown
spectroscopy and
obtaining corresponding
elements wavelength of
sample under test
through the calibration
pf spectral graph. |
