The PureSniff system allows for the standardized presentation of undiluted odor samples. With a PureSniff device, you can conduct odor evaluations including  overall intensity, hedonic tone, and odor character profiling.

The PureSniff allows for in-house assessments for product development, material investigations, and QA/QC.

PureSniff II

The PureSniff II consists of two sealed tubes, which are set up with gas sample bags independent of each other, allowing for individual or direct evaluation comparison tests.  For example, each tube can be set up as two separate samples for evaluation or duplicates of the same sample.  Alternatively, comparison tests such as paired comparison/preference or directional difference tests of A vs B can be run.

The operator triggers a volume flow by activating a push-button.  The odor sample is pushed out of the gas sample bag and press through a funnel (diffuser) mask to the human nose.  Each olfactory assessors gets an identical odor sample with standardized volume flow and constant presentation time.  As a default setting, the samples is presented for 2.5 seconds at a volume of 20-LPM.

Using a 10-L gas sample bag filled to approximately 70%, one sample serves for about 10 presentations.

PureSniff III

The PureSniff III consists of three sealed tubes, which are set up with gas sample bags independent of each other, allowing for individual or direct evaluation comparison tests.  For example, each tube can be set up as three separate samples for evaluation or duplicate/triplicate of the same sample.  Alternatively, discriminations tests of 2-3 samples can also be run.  Examples include triangle tests, 3-AFC, or A – not A. 

The operator triggers a volume flow by activating a push-button.  The odor sample is pushed out of the gas sample bag and press through a funnel (diffuser) mask to the human nose.  Each olfactory assessors gets an identical odor sample with standardized volume flow and constant presentation time.  As a default setting, the samples is presented for 2.5 seconds at a volume of 20-LPM.

Using a 10-L gas sample bag filled to approximately 70%, one sample serves for about 10 presentations.

PureSniff XL

The PureSniff XL consists of one large sealed tube, which is set up with a gas sample bag, allowing for direct evaluation.  Once sample is tested at a time.

The operator triggers a volume flow by activating a push-button.  The odor sample is pushed out of the gas sample bag and press through a funnel (diffuser) mask to the human nose.  Each olfactory assessors gets an identical odor sample with standardized volume flow and constant presentation time.  As a default setting, the samples is presented for 2.5 seconds at a volume of 20-LPM.

Up to 60-L sample bags can be used in the PureSniff XL.

The PureSniff systems require an external air supply to provide 30-70 psi (2-5 bar)
