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.
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
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
With a fully charged battery the FROG-4000™ will run continuously for about 6 hours.
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
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.
A calibration for the FROG lasts 3 weeks. After 3 weeks the percent recoveries may be less than 90% or greater than 110%.
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.
Yes, calibration is necessary for proper use of the FROG.
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.
