GDA-Fumigation
The GDA-F allows a quick and safe chemical inspection of import containers. The GDA-F is a portable detector which is operated directly at the container and is able to respond within seconds if dangerous concentrations of hazardous chemical substances are detected there. The GDA-F comprises a Hybrid Sensor Array, meaning that the detection will occur simultaneously through several sensors. By using the different sensors it is possible to obtain the necessary broad range for measuring the necessary chemicals. For example, it is possible to detect very light and hazardous chemicals like chlorine gas, phosphine or hydrogen cyanide, among others, as well as more complex organic gases like chloropicrin or benzene. This is something that no other type of detector can do on its own.
Through intensive studies with users from customs and logistics, optimized procedures on how to set up and operate the instrument have been developed. Important features of the instrument are easy handling and output, the speed of measurement and the ability for continuous supervision during unloading procedures. The high level of safety achieved by GDA-F is fundamental to win the confidence of the users.
Many studies have been carried out around the world showing that the air in containers coming from abroad may contain hazardous concentrations of various gas compounds. Beside recognizing the designated fumigation gases used in cargo-containers the GDA is able to detect non-conforming chemicals or other gases due to evaporation from goods, all of which may cause a health risk. The inspection of Import-Containers for a possible variety of gas compounds is made easily by the GDA detection system. The level of chemicals and the risk potential of the air inside a container can be detected in seconds. The best way of handling and treating the gases can be determined instantly.
The GDA Fumigation:
• detects the relevant fumigation gases and other toxics
• Provides safety beyond defined target gases by alarming on hazardous concentrations
This unique set allows:
• coverage of a broad range of chemicals
• detect and alarm at relevant concentration levels
• running of an analysis in seconds (typically 15 sec)
• receipt of an easy result in a fail safe procedure
• supervision of the working environment during unpacking with continuous measuring
The internal cleaning procedure provides short measurement cycles and prevents system overloads.
• Broad coverage of chemicals
• Easy handling, short training, self supervision, high availability
• Handheld operation
• Data logger
• Off-line data evaluation
• Provides safety beyond defined target gases by alarming on hazardous concentrations
Some important characteristics of the GDA:
• Security by detecting a very wide range of chemical substances: the hazardous substances will be definitively detected. Besides the defined fumigants the GDA is able to detect other toxic substances.
• Easy to use, 2 button operation
• Results are given within seconds (about 15 sec)
• 20-30 containers may be measured within an hour
• Wide dynamic detection range (ppb up to upper ppm)
• Security of alarms: no false negative
• Short training and instruction time
• Continuous operation
• Time win when comparing this with other measurement procedures (GC/MS or colorimetric tubes...); no sample degradation
Features:
• Operating temperature is 0°C to 45°C
• The instrument is portable (about 4.5 kg)
• Battery operating time 4hrs
