HAGUE-7000
C-14 sampler
Description
The C-14 HAGUE-7000 bubbler is a modern device intended for the efficient capture of radiocarbon (C-14) in flue gas emissions and radioactive gases. The device operates on the principle of barbotage through a sodium hydroxide solution, enabling the reliable collection of airborne C-14 in various chemical forms: CO₂, CO, and organic compounds. CO₂ is directly captured in the first two vials, while CO and organic carbon are oxidized in a high-temperature furnace, releasing CO₂, which is then captured in the remaining vials.
The technical solutions implemented in the HAGUE-7000 make the device highly convenient and safe to operate. Its ergonomic design and unique dynamic sealing system with four vials allow for easy start/stop operation without the risk of leakage or solution loss. Thanks to the built-in cooling system, liquid evaporation is significantly reduced, allowing the sampling frequency to be decreased to once a month. All operational parameters are controlled by a microprocessor, ensuring stable performance, high measurement accuracy, and full safety even during long-term use.
The housing is made of a lightweight and durable aluminum alloy with a scratch-resistant coating. All key components — glass cylinders, tubing, catalyst, and filters — are manufactured from high-quality materials, ensuring longevity and reliable operation. For ease of transport, the device is equipped with a system of three handles designed for two operators.
If desired, the device can be equipped with an additional water cooling system that maintains the liquid temperature in the cylinders between +6°C and +15°C, reducing evaporation and improving operational stability. This system can be easily installed on both new and existing bubblers.
The furnace temperature is maintained within specified limits (from +200°C to +500°C), ensuring high catalytic oxidation efficiency.
Ultimately, the liquid samples collected by the device are analyzed in a laboratory using Liquid Scintillation Spectrometer TRIEL, which allows determination of the radiocarbon content in the air. The obtained data, taking into account the volume of air passed through the system, enables accurate calculation of the C-14 concentration in the monitored environment.
Application
The HAGUE-7000 is applied for optimal monitoring of atmospheric radiocarbon C-14, effectively capturing both gaseous and organic forms of carbon from various sources. This device is widely used at nuclear power plants, nuclear research centers, radioactive waste storage and processing facilities, laboratories, as well as at waste incineration plants and decommissioning projects where monitoring of C-14 emissions is required.
The operating principle is based on bubbling in a soda solution, which reliably traps gaseous C-14, while organic compounds are pre-oxidized to ensure high measurement accuracy. The trapping efficiency reaches 100% for CO₂ and 94% for the conversion of carbon from methane to CO₂.
The instrument is designed in accordance with NF ISO 20041-1 standards, ensuring high performance and ergonomic operation. An optional cooling system maintains the solution temperature at around 7°C, preventing evaporation and ensuring stable operation, which significantly extends the intervals between sample collections.
