APPLICATION STORY
Linking Enzyme Detection with
Mobile GC/MS Analysis
FLIR Agentase C2 Chemical Agent Detection
FLIR offers a total solution for the detection and identification of chemical threats from
early warning and incident response to decontamination missions.
Protecting people and property from the use of Weapons of Mass Destruction (WMD) requires a
tiered approach to secure the homeland. The primary mission varies from the needs of the front-line
operator to the central command station. From detection and identification to decontamination, each
event across the timeline requires a specific set of capabilities to result in an actionable outcome. A
tiered approach is needed that takes into account both the type of threat and the capability needed
based on the time allotted for an operator to complete their mission.

FEATURES & BENEFITS
Agentase C-Series Products:
Griffin GC/MS Products:
The FLIR Agentase C-Series products combined
with the Griffin™ mobile Gas Chromatograph/Mass
Spectrometer (GC/MS) provides a total solution
for chemical threats. During incident response,
C-Series presumptive screening tools provide front
line operators with rapid threat alarms at levels no
other technology can detect, safeguarding lives.
They do not destroy the sample and can even
be used to collect a sample. During the recovery
phase, additional FLIR sampling tools like the
Griffin X-Sorber are used to collect samples in the
hot-zone. With little to no sample preparation, the
chemical identity is confirmed within minutes via the
mobile Griffin GC/MS. The Griffin GC/MS system
ensures that the user is armed with confidence – no
matter where the action takes them.

DETECTION WITH ENZYME-BASED SENSORS
The Agentase C-Series sensors utilize enzyme based technology to produce colorimetric detection results
(Figure 1). They enable the user to detect chemical warfare agent (CWA) and/or Toxic Industrial Chemical
(TIC) contamination on surfaces or in air directly in the hot-zone. The enzyme based sensing technology
offers an extremely low false positive rate and offers single microgram-level sensitivity on surfaces.
FORENSIC ANALYSIS VIA MOBILE GC/MS
GC/MS is the laboratory gold standard for chemical analysis. It is a highly selective and specific technology
that can differentiate between similar chemical structures in a single, complex sample mixture. This aids
in quick and accurate chemical identification. Chemical emergencies can happen anywhere. Griffin GC/MS
systems deliver lab quality forensic analysis in a field-ready package that anyone can use.
INCIDENT RESPONSE
It is difficult to detect CWAs prior to use. Early warning is mission-critical. Security personnel need to be
alerted within the first few minutes of something happening. The ability to detect trace levels of hazards
quickly can protect people from low-level, long-term exposure and save lives. It is imperative that the first
indicators do not result in false alarms and cause unnecessary panic. These initial presumptive results
typically drive a confirmatory measurement that focuses on making sure that a real event has occurred prior
to taking high regret actions.
Figure 1 – Chemical Agent Located on Surfaces
First on-scene operators employ the Agentase™ C1 chemical agent sensor to rapidly detect class-specific
agent contamination on a variety of surfaces after a suspected attack. Operators conduct surface, solid and
liquid interrogation for the presence of nerve (G&V series), blood (AC) and blister (HD) agents, acids, bases,
aldehydes and oxidizers (Figure 2). The sensors do not destroy the sample and can be saved for eventual
forensic analysis via GC/MS. Detection occurs within five minutes and the results are easy to read. This
presumptive screening tool offers the speed and accuracy required for incident response missions.
During the recovery phase, forensic analysis is often needed to positively identify the threat used in the
attack. The Griffin GC/MS system is most often deployed in the cold-zone in a temporary tent structure,
deployable lab or other vehicle (Figure 3). The system is provided with the Griffin X-Sorber, a handheld vapor
sampler for use in the hot-zone (Figure 4). Front line operators collect a sample after positive detection
from the Agentase C1. The X-Sorber moves through the decon line and, without any sample preparation,
the operator plugs it into to the Griffin GC/MS for automated desorption and analysis. Within minutes, the
operator receives a red or green alarm with confirmatory identification of the chemical agent used in an
attack. This on-scene actionable intelligence arms the operator and their command center with confidence.

CLEAN UP
After an attack has been confirmed, the mission focuses on effective response measures. Operations such as contamination mapping (both people and property),
treatment of casualties and expeditious decontamination are swiftly undertaken to reduce potential loss of life. Providing for an understanding of where the threat
actually went is a difficult operation, but is absolutely imperative in providing for an effective response.
Decontamination efforts can be costly when the specific areas of contamination are hard to locate on a surface. Out of an abundance of caution, users must
apply decontaminant where it is not needed. The Agentase C2 is sprayed directly onto a surface to reveal specific CWA contamination, specifically nerve agents
(G- & V-series) and sulfur mustard (HD). Within five minutes, the product application alerts the operator when an area is found that has been exposed to chemical
contamination or is in need of further decontamination (Figure 5). Agentase C2 enables users to focus their application and reduce the amount of decontaminant and
water used, decreasing costs by three to five-fold.
The sample preparation after a positive detection by Agentase C-Series products is very simple (Figure 6). After the threat agent has been located, the operator uses
a swab to touch the contaminated area. This swab is diluted in an organic solvent. A standard liquid syringe is used to extract a small amount from the diluted sample
and is injected directly into the Griffin GC/MS for analysis and rapid confirmation.
SUMMARY
Across the timeline, security personnel, first responders, emergency managers and military officers need the right tools for the job. Lab-quality, field-proven
capabilities are needed from detection to decon and everything in between. With use of the Agentase C-Series products and the mobile Griffin GC/MS, operators
go from detection to confirmation in less than 30 minutes. The Agentase C-Series arms front-line operators with fast, presumptive detection before human harm
or loss of life can occur. Confirmatory identification offered by the Griffin GC/MS helps facilitate appropriate decontamination response. The ability to perform
on-site chemical analysis eliminates the expense of shipping unwanted samples and instead allows you to ship only the evidence needed for chain of custody. The
implementation of a systems-based approach will instill confidence no matter where the mission is.
