Application Cases:
1. Heavy metals detection in soil
Simply trigger the instrument, and you will
know the trace metal elements in soil.
2. Emergency treatment after heavy
metal pollution
Can quickly on-site trace the pollution
and circle the polluted boundary.
3. Screening of heavy metals polluted
samples in large amounts
The fourth generational handheld
EDX-POCKET-IX can circle the key
pollution areas in very short time, for
key management.
Can rapidly distinguish the polluted areas
and non-polluted areas .It improves the
screening and productive rate integrally,
& greatly reduces the cost of chemical
examination and transportation.
