FROG-5000™
Portable GC PID, Micro Gas Chromatograph with Photoionization Detector
Volatile Organic Compound (VOC) Analysis for Air, Water, and Soil Samples
THE WORLD’S FIRST COMMERCIAL MEMS GC AND MEMS PC
The FROG-5000™ can detect volatile organic compounds (VOCs) in air, water, and soil, delivering lab-quality results in less than 10 minutes. It is the only portable gas chromatograph that weighs less than 5lbs (2.2kgs).
The FROG-5000™ portable GC will detect chemicals as volatile as vinyl chloride in addition to semi-volatile organic compounds such as naphthalene. It can detect VOCs at sub-part-per-billion levels or at high part-per-million levels depending on its configuration.
FROG operators use it to determine trace amounts of suspected chemical contaminants without waiting for results from an offsite lab. Within ten minutes you’ll have an answer in the field and you’ll know how your cleanup is progressing. The FROG can help you correct the job and fix it on the spot!

CONCLUSION
The Defiant Frog 4000 performed as well, if not better, than traditional dedicated laboratory analytical systems in the performance of BTEX+MTBE analyses. This statement is based on the evaluation of the calibration curve, the low concentration of the MDLs, and the low Z-Scores of the extrenally administered laboratory proficiency studies.
Assigned Value: Value attributed to a particular quantity and accepted, sometimes by convention, as having an uncertainity appropriate for a given purpose. See ISO/IEC 17043 for additional information. In general the assigned value is the value used to assess proficiency and may or may not be the made to value (gravimetric value).
Accept. Window: The range of values that constitute acceptable performance for a laboratory participating in this PT study.
Z: A Z-Score tells how a single data point compare to normal data. A Z-Score says not only whether a point was above or below average, but how unusual the measurement is. Generally, a method result with a Z-Score less than |2| is considered to be in control, a Z-Score between |2| and |3| is considered ‘Questionable’, but still within control and a Z greater then |3| is considered not acceptable and the method is out of control. For WS studies, a z-score greater than |2| is unacceptable. Calculated as Z=(Reported Value – Assigned Value)/Proficiency Std. Dev.
