Fire Investigation Kit

The ION Science Fire Investigation Kit with Tiger or TigerLT photoionisation detector (PID) has been specifically designed to provide you with all the tools for a convenient, easy-to-use solution for the detection of volatile organic compounds (VOCs) within Fire and Arson Investigation applications.

Fire investigation teams are responsible for the examination and assessment of suspected arson-related sites, and further analysis of suspicious samples.

In suspected arson cases, it is part of the investigation to prove that there is no other cause of the fire. The ION Science Fire Investigation Kit can be used to detect hydrocarbon compounds such as those found in petrol, alkanes, and cycloalkanes. Fire investigators including the police, consultants and private investigators acting on behalf of insurance companies, will search for every type of fire accelerant such as grill lighters, lighter fuel, liquid glue and cleaning agents.

In the aftermath of a fire, significant values can already be 1-20 parts per million (ppm). Depending on the period of time between the occurrence of the fire and the examination, potential VOC gases might have partially disappeared. As a result, values always vary and sometimes the measured values can reach 100 ppm or more.

The extinguishing foam used by fire teams contains proteins and other hydrocarbon compounds which can produce falsified results and make usable measurements difficult.

Investigators require a solution for the fast discovery of potential arson incident accelerants, and initial crime scene VOC assessment.

Both the Tiger and TigerLT PIDs are perfect for arson investigation. The instruments have a rugged design, are ready to use within seconds, easy to operate with gloves.

Both models incorporate Ion Science’s market-leading PID technology with patented fence electrode system. The advanced three-electrode format ensures increased resistance to humidity and contamination for ultimate reliability and accuracy in the field, as well as reduced drift issues and extended run time.
