The Frog and the TOCAM™ are capable of detecting many different volatile organic compounds (VOCs). The majority of the FROG and TOCAM™ 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 or the TOCAM™ 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™ or TOCAM™ from your website?dtnewadmin2020-02-06T18:56:30+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 TOCAM™?dtnewadmin2020-04-04T17:48:07+00:00
The main difference is that the FROG™ may be used for soil, water or air sampling. The TOCAM™ may only be used for air sampling, and is primarily for distributed, fixed, or perimeter monitoring. The TOCAM™ also has an additional PID to simultaneously detect for total VOCs. System integrators will find the TOCAM™ to be a very compact low power solution for distributed sensing applications.
What concentration unit does the software report the results in?dtnewadmin2020-02-06T18:55:44+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 or TOCAM™ myself?dtnewadmin2020-04-04T17:40:54+00:00
Yes, we offer calibration kits for FROG water calibrations. For FROG or TOCAM™ 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?dtnewadmin2020-02-06T18:51:23+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 Portable Gas Diluter and the Inline Diluter?dtnewadmin2020-04-04T17:50:54+00:00
The Portable Gas Diluter is used to calibrate the FROG or TOCAM™. The portable gas diluter enables the user to mix various known concentrations from a single calibration gas cylinder. An internal compressor supplies the dilution gas in the Portable Gas Diluter, or it can be connected to a supply tank of dilution gas. The Inline Diluter is used for diluting high concentration samples for the FROG™ or TOCAM™. An internal scrubber provides dilution air for the Inline Diluter.
How long does a calibration last?dtnewadmin2020-02-06T18:45:47+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.
What is the difference between the Portable Gas Diluter and the BASS-100™ Gas Diluter?dtnewadmin2020-04-04T17:49:27+00:00
The Portable Gas Diluter uses ambient air as the dilution gas and was designed for field use, with dilution ranges of 200:1. The Portable Gas Diluter must be manually adjusted to a desired concentration. 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.
What are the shipping dimensions for the FROG-4000™ and FROG-5000™?dtnewadmin2020-02-06T18:49:38+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?dtnewadmin2020-02-06T19:41:28+00:00
