Can I use the FROG to analyze for a certain compound?2022-04-04T15:41:29+00:00
The FROG is capable of detecting many different volatile organic compounds (VOCs). The majority of the FROG applications are for BTEX (Benzene, Toluene, Ethylbenzene and Xylenes), Chlorinated Alkenes (cis-1,2-Dichloroethene, trans-1,2-Dichloroethene, Trichloroethene, and Tetrachloroethene), and Naphthalene. However, the FROG can be used for other applications. Please reference our Application Notes page to see other applications or the product brief and feel free to contact us regarding your application.
Can I download the software for the FROG™ from your website?2022-04-04T15:43:21+00:00
Currently software is not available on our website. Please email info@defiant-tech.com, or call 505-999-5880 to obtain software.
Is calibration for the FROG required?2022-04-04T15:38:29+00:00
Yes, calibration is necessary for proper use of the FROG.
When do I need to change the scrubber material on the FROG?2020-02-21T19:01:52+00:00
The FROG uses air as the carrier gas and uses scrubber material (activated carbon and molecular sieve) to clean the air. The frequency at which these need to be replaced varies with how often the Frog is used and the cleanliness of the environment it is used in. For daily FROG use we recommend replacing the scrubber material every month, for weekly (or infrequent) FROG use, we recommend replacing the scrubber material every 3 months. Watch a video about how to replace the scrubber material.
What is the difference between the FROG and the VOCAM™?2022-04-05T16:32:51+00:00
The main difference is that the FROG™ may be used for soil, water or air sampling. The VOCAM™ may only be used for air sampling, and is primarily for distributed, fixed, or perimeter monitoring. The VOCAM™ has a heated PID to keep the PID lamp cleaner for longer periods of time. In addition, VOCAM™ has a regenerable hydrocarbon scrubber. System integrators will find the VOCAM™ to be a very compact robust solution for distributed sensing applications.
What concentration unit does the software report the results in?2020-02-06T18:55:44+00:00
The software reports the concentration in the same units that the instrument was calibrated in. If Defiant calibrated the instrument, then the concentration unit is parts per billion (ppb) for water and parts per billion by volume (ppbv) for air.
Can I calibrate the FROG myself?2022-04-04T15:37:01+00:00
Yes, we offer calibration kits for FROG water calibrations. For FROG Defiant Technologies offers calibration services and training courses that cover how to calibrate these instruments as well as the BASS-100™ Calibration Gas Diluter.
How do I adjust retention times? Why do I need to do this?2020-02-06T18:51:23+00:00
When the FROG is calibrated at a different location than the one it is being used at adjusting retention times is necessary, due to differences in barometric pressure and/or altitude. You can adjust retention times by running the retention time check sample and following the instruction sheet provided with your calibrated Frog. It is important that the retention times are adjusted properly prior to sampling.
What is the difference between the Inline Diluter and the BASS-100 Gas Diluter?2022-04-04T16:04:28+00:00
The Inline Diluter is used for diluting high concentration samples for the FROG™. An internal scrubber provides dilution air for the Inline Diluter. The BASS-100™ Gas Diluter has a seamless interface with the Ellvin™ software, so it can automatically generate data for a calibration. The BASS-100™ requires a dilution gas and sample gas supply. It can provide a dilution range of 500:1.
How long does a calibration last?2020-02-06T18:45:47+00:00
A calibration for the FROG lasts 3 weeks. After 3 weeks the percent recoveries may be less than 90% or greater than 110%.
What sort of maintenance do the FROG-4000™ and FROG-5000™ require?2020-02-06T18:50:36+00:00
Routine Maintenance on the FROGs include exchanging the scrubber material. Calibration is also required every 3 weeks for proper analysis with the FROG. Defiant also offers an annual service contract available for purchase.

My flashlight/timer/security light/power strip isn’t working, can you help me fix it?2020-02-06T18:57:19+00:00
There is a different company by the name of Defiant. We produce gas chromatography instruments and accessories, not flashlights. Please contact the company you purchased your flashlight/timer/security light/power strip from.
I was loading a sample to the FROG-4000™ and 2 white rings fell off. What are these?2020-02-06T19:41:28+00:00
These rings are Teflon ferrules that allow the sparge bottle or air sampler to seal onto the front of the FROG-4000™. It is important that they are installed correctly. Watch a video showing how to re-install them.
How long can I run the FROG-5000™ using battery power?2020-02-06T18:48:34+00:00
The FROG-5000™ has a Lithium Ion battery which lasts for 9 hours when fully charged.
I noticed that there are two USB Cables in the FROG-4000™’s case. What is the difference?2020-02-21T18:59:30+00:00
The difference between the USB cables are the non-USB ends. One of the cables has an auxiliary cable end, this cable is the serial data cable, it is used for connecting the FROG-4000™ to the Ellvin™ GC software to run the FROG-4000™ live with the software. The other cable has a micro USB connector on one end, this cable is used for extracting data files from the Frog’s memory. Watch a video about how to connect your Frog to the Ellvin™ GC software using the serial data cable.
How long can I run the FROG-4000™ using battery power?2020-02-06T18:53:03+00:00
With a fully charged battery the FROG-4000™ will run continuously for about 6 hours.
