Identifying chemical threats, detected
with an AP4C + S4PF/S4PE, can be done
easily and quickly with Arx handheld Raman
using the Serstech Arx and SERS
(Surface Enhanced Raman Spectroscopy).
Identifying chemical threats, detected
with an AP4C + S4PF/S4PE, can be done
easily and quickly with Arx handheld
Raman using the Serstech Arx and SERS
(Surface Enhanced Raman Spectroscopy).
To combat chemical threats in the fi eld,
suffi cient equipment for detection and
identifi cation of such threats is required.
These tools must comply with the
demands set by the tough conditions
where they are needed e.g., small size, light
weight, durable, easy to use, and accurate.
The AP4C by Proengin fulfi ll these
requirements and can detect potentially
hazardous gases. Whenever a liquid or
solid is suspected to contaminate a
surface, the S4PF/S4PE can be used to
determine whether the material is organic
and/or containing sulfur (S), nitrogen (N),
phosphorous (P), or Arsenic (As).
For accurate more identifi cation, Raman
spectroscopy is commonly utilized. If
suffi cient material is available, a direct
measurement with a handheld Raman
device can be carried out in seconds.
If only a small amount of the sample is
available, it can still pose a signifi cant
threat. The SERS4PF is then used to
safely and effi ciently transfer the sample
collected with the S4PF/S4PE to the SERS
substrate via solution. SERS allows for
identifi cation of trace amounts (ca 0,1 mg)
of sample even after being heated with
S4PF/S4PE.
