How often should I change the gasket seal between the electronics module and the glass bottle?
How often should I change the gasket seal between the electronics module and the glass bottle?
You should replace the gasket whenever it appears damaged. If you open and close the bottles once a week (on average), you should replace the gasket once every six months.
When should I replace the red septa if it has been pierced with a GC needle?
When should I replace the red septa if it has been pierced with a GC needle?
The red septa can be used repeatedly during a study as it reseals quite effectively when the needle is withdrawn. When it is being pierced during sampling of gasses it is important to use a small gauge needle and avoid puncturing the membrane in the same location. The red septa are found in Septa Bottles (7120, 7130, 7131 and 7132) and replacement 10 packs are available as part RF35. With a PTFE layer on both faces, it offers very low CO2 permeability compared to a standard silicone septum and, when new, contributes only about 0.001psi loss per hour through permeation. It is recommended that used septa be replaced before starting a run as CO2 permeation increases slightly each time a septum is pierced with the GC needle. If you opt to re-use septa for a specified number of uses be aware that with each penetration of a 10 µL (0.017" diam.) GC needle the CO2 permeation increases by about 0.001 psi/hr. So, when septa bottles are used in a study, use a septa bottle for your blank as well and pierce the septum on the blank with the needle as you do the rest of the samples to factor out the increased CO2 permeation. For further discussion on the use of a blank, see RF Getting Started Guide.

Why is the Solenoid cylinder in the module getting hot?
Why is the Solenoid cylinder in the module getting hot?
The Solenoid cylinder in the module is part of the valve assembly. During a test while recording, normal valve openings are very brief and within range of 10-1000 milliseconds, which does not cause the Solenoid cylinder to get hot. If the "Open Valves" button is clicked or "Valve Open" check box (in the GPM software screen) is checked, the valve is continuously held open. The software will limit that period of time to 3 minutes, however it may still get rather hot. If using this function be sure to start with a fully charged battery as the "Valve Open" function has a significant drain on the battery. As soon as there is no need to have the valve open, click the "Close Valves" button or uncheck the "Valve Open" check box to avoid unnecessary use of the Solenoid and drain on the battery.
Can static electricity damage my ANKOM RF Gas Production System?
Can static electricity damage my ANKOM RF Gas Production System?
Therefore, we highly recommend using an ANKOM Anti-Static wrist strap (RF50) when plugging or unplugging the RF16 or RF46 (dual lead) rechargeable battery packs in your RF1/RF5 modules.
What is the support for Gen 2 systems?
What is the support for Gen 2 systems?
ANKOM expects to be able to fully support the GEN2 system with all replacement parts for the next 6 months, possibly longer. Due to supply chain issues we will eventually be unable to replace the RF45 chip and the 7007 Circuit board. Chip reprogramming can still be done. All other repairs and replacement parts (RF31 Pressure sensors, RF11 Viton-silicone tube assembly, etc.) will continue to be available indefinitely.
Can you clarify how this migration from GEN2 to GEN3 will be done?
ANKOM is continuing to sell add-on and replacement RF1 modules for existing GEN2 RFS kits up to a total of 20 modules. At some point in 2023 we expect that will no longer be possible. All new RFS systems are using the GEN3 modules.
If I need some component, will you be able to provide it?
We expect to be able to fully support repairs on Gen 2 systems through the end of 2022.
