Arson Investigation

MiniCan and Bottle-Vac samplers are ideal for investigating the presence of accelerants at a burn site. Vapor phase samples can be collected directly using Restricted Samplers (see page 64), or Solvent Enhancement Enclosures (SEE) The self-contained vacuum pulls the sample into the container without a power source requirement.

Using MiniCans and Bottle-Vacs can also speed up collection and analytical processes, as well as improve upon the sensitivity of accelerant determination. Currently, site investigations are often performed by placing a carbon strip into a paint can containing debris and then waiting up to 24 hours before removal of the carbon strip to perform a solvent extraction.

Entech oers an improved “paint can” collection solution which offers the benets of MicroValve sampling technology. Debris to be tested is collected into a paint can as usual, and a new can cover with a female Micro-QT valve is used to create a leak-tight seal onto the top of the paint can. Then,some of the can’s headspace is extracted into an evacuated MiniCan or Bottle-Vac. Analysis of just 100cc of this headspace eectively increases the detection limit of this technique by 50–100x while eliminating the any need for extraction solvents,making this approach more GCMS friendly. Analysis can be done quickly,with a same day sample turn around if required, and Arson Investigators may continue to use tried and true sampling methodologies they are comfortable with.

Emergency Response Sampling(ERS)

Monitoring for chemicals in response to accidental releases requires the sampling device to be mobile and easy to use. It should also be small, light and inexpensive. The MiniCan fits this description better than any other sampling device available. Featuring a Silonite coated interior, the MiniCan becomes an essential, portable and cost eective extension of the GC analytical process. MiniCans and Bottle-Vacs collect the entire sample, rather than trying to perform dicult separations right at the point of release (tube sampling). These vacuum samplers allow recovery of a wider range of ammable compounds than any other sampler, including chemical warfare agents and toxic industrial compounds from C2 to C25, and polar compounds as light as methanal. Even compounds like formaldehyde that were once thought to require derivitization can be sampled and analyzed directly by GCMS.
