FROG-5000™ Portable Gas Chromatograph GC
Detecting Volatile Organic Compounds VOCs in Water
When equipped with its glass sparge bottle, the FROG portable gas chromatograph can detect volatile organic compounds (VOCs) in water down to sub-part-per-billion concentrations.
Water samples can be run onsite to reduce shipping and laboratory costs. This is particularly valuable for monitoring multiple monitor wells.

FROG Water Analysis – Water Sampling Study
There was suspected dumping of dry cleaning solutions.
Douglas Adkins, Co-founder and Senior Engineer, and Patrick Bingaman, Application Chemist, from Defiant Technologies went to work with the state of Kansas to survey the site. A total of 8 locations were sampled, with the samples being run onsite. The FROG portable gas chromatograph was attached to a computer, allowing the data to be studied in real-time with the Ellvin™ software.
It was concluded that most of the contamination was fuel-type products setting on top of the water table.

FROG Water Analysis – Extraction Well Study
Defiant’s FROG-4000™ portable GC was used to identify and determine the concentration of chlorinated alkenes in several extraction wells located in Tacoma, Washington.
These wells are in a superfund site where a former paint and lacquer thinner manufacturer and an oil recovery facility existed. Split samples were taken at each well and sent to an offsite lab for analysis. Co-Founder and Senior Scientist Patrick Lewis, Co-Founder and Senior Engineer Douglas Adkins, and Application Chemist Amanda Trujillo were on-site analyzing comparative samples with the FROG.
This field exercise highlighted the high degree of agreement between the offsite lab and the FROG-4000.
