To better serve the Canadian market, St. Croix Sensory opened its first international odour laboratory in Toronto, Canada in February 2023.
St. Croix Sensory – Canada , is a third-party odour laboratory, dedicated to providing quality odour data and exceptional customer service to our Canadian clients. The laboratory offers a full range of olfactory evaluations, including thresholds, characterization, intensity and persistency values.
AC’SCENT Flux Chamber is a surface emission isolation hood designed for solid or liquid surface sample collection. Our Flux Hood follows US-EPA recommended design parameters for isolated surface emission collection.
Set the AC’SCENT Flux Chamber directly on a solid surface or on a liquid surface with the included float. Use a clean odour-free sweep gas, either zero-air, high purity nitrogen or nitrogen with a helium tracer component. You follow your project protocol for sweep gas and sampling rates.
Overall Hood Diameter: 0.14 m (16″)
Surface Area under Hood: 0.13 m2
Four Ports: 1) sweep gas/air;
2) sample line;
3) excess gas/air vent; and
4) optional thermocouple probe.
Included Rope: 50′ – 3/8″ Nylon Braided Rope
Included Flotation: Standard 16″ Tube
Sweep gas supply and regulator NOT included.
Q: Does the AC’SCENT Flux Hood comply with EPA sampling methods?
Yes, see EPA document PB86-223161, “Measurement of Gaseous Emission Rates from Land Surfaces Using an Emission Isolation Flux Chamber.”
Q: When I use the Flux Hood what flux gas/air do I use?
The protocol for your project may dictate zero-air or high-purity nitrogen (HPN) with or without a helium (He) component.
Q: What is a typical sweep gas (air) rate?
25-liters per minute per square meter is a typical sweep gas rate, which is 3.5-LPM for the 0.13-m2 under the AC’SCENT Flux Hood.
Q: What is the typical sample collection rate?
The Sample collection rate depends on your project protocol; a typical sample collection rate is 1 to 2 LPM.

The Nasal Ranger has been instrumental in determining a reference value for odor nuisance investigations in response to odor complaints in Thailand. In May 2020, the Journal of Health Research, published by Emerald Publishing Limited, published the article “Odor Intolerance and proposed off-site limit under the Thailand public health provision” (Hirunrueng, Patthanaissarnukool, Sihabut). The articleContinue reading "Thailand Public Health Provision For Off-site Odor Emissions"
