Model OdorPrep® V3 -Sample Collection
The integrated system for continuous air quality monitoring and on-demand sampling of olfactory harassments. OdorPrep® V3 is equipped with an integrated control panel and comes with its own dedicated mobile applications for the remote control of the system, allowing the operation of all sample lines, or individually as required. The OdorPrep application is available via Play Store©. 3 sampling methods are available. Image for illustrative purposes. On-demand odor sampling method to EN13725 (Nalophan™ bags) The sampling line has an adjustable flow valve allowing sampling versatility. Duplicate or individual samples can be taken to allow for maximum flexibility and improved collection of the odorous air. The sampling lines are equipped with a protection system to preserve the sample following collection.
The sampling, storage and transport containers of the sample are rigid and sealed to avoid exposure to direct sunlight (two containers included for each sampling line), in order to minimize any chemical (photo)reactions and diffusion (as foreseen in the standard EN13725). The containers are returned for analysis in an accredited laboratory.

On-demand sampling module on Canister
The sampling line is equipped with a control unit for the remote opening and closing of the specialist valve, a dedicated digital pressure sensor monitors any vacuum losses while the sampler is operational.
The duration of the sampling depends on the restrictor used. Below are some examples of sampling durations depending on the restrictor and the Canister volume.

The canister sampling lines are independent. Sampling can be performed on several lines simultaneously or in sequence. The sampling unit is equipped with a temperature control system to allow the correct storage of the samples and the sampling temperature above the dew point, avoiding condensation. At the end of the sampling period a notification is sent to the operators so that collection of the canisters can be arranged.
Different configurations available for on-demand sampling are shown below.
