Supelco radiello™ Passive Air Sampling Devices for Ambient, Indoor and Personal Monitoring

radiello is the ideal device for sampling low levels of Hydrogen Sulfide (H₂S), aldehydes, BTEX/VOCs, SO₂/NO₂/HF, ammonia, and other compounds in many applications such as sampling in petrochemical environments, vapor intrusion, sick building/house and LEED.

Features and benefits of radiello samplers

1. The radial design of radiello samplers offers high uptake rates resulting in faster sampling (over axial samplers)
2. Greater adsorbent capacity offers minimal reverse diffusion and greater uptake rate consistency resulting in more reproducible results.
3. All uptake rates are precisely measured (not calculated) resulting in more accurate measurements.
4. The water repellent diffusive body makes radiello amenable for use in bad weather
5. All cartridge adsorbents undergo a complex conditioning and QC procedure resulting in cartridge background levels three times lower than instrument noise.
6. The combination of low detection limits, high uptake rates and high capacity allowing for sampling time ranges from 15 min to 30 days (1 ppb – 1000 ppm range).
7. Other benefits include, but are not limited to:

• Predominately solvent/chemical desorption which does not require thermal desorption equipment
• Amenable to thermal desorption & GC/MS with low interferences resulting in precise and very sensitive measurements
• Touch and chemical inertness makes the sampler robust for use
• Reusable hardware for more economic sampling costs

radiello samplers are available for the following contaminants:
BTEX/VOC’s in Chemical and Thermal Desorption
Aldehydes
Ammonia (NH₃)
HF, NO₂, and SO₂
Ozone (O₃)
Anesthetic Gases and Vapors
Phenolic Compounds (Thermal Desorption)
HCl
1,3-Butadiene and Isoprene
