INTRODUCTION
The Getxent Remote Air Sampling Canine Olfaction system - Getxent
RASCO - is a unique affordable solution to collect and concentrate volatile
from huge volumes.
The Getxent RASCO system is based on the combination of the Getxent
tube and a specially designed accessory to plug on a Dyson or a Xiaomi
vacuum cleaner. The patented technology of the Getxent tube
(WO2018206808) is based on an innovative polymer able to capture all the
molecules constituting an odor. Once captured, the Getxent tube releases
them accurately. Thanks to the Getxent RASCO accessory (patent pending),
the Getxent tube can now be plugged on a Dyson or a Xiaomi vacuum
cleaner to collect and concentrate the odor in huge volumes such as
rooms, freight containers, cars, trucks, and planes. The process only takes
few minutes. The presence of the odor can be checked immediately or later
by trained dogs.
The Getxent RASCO accessory has been especially designed to optimize
the air flow around the Getxent tubes and to be compatible with one of the
most performing portable vacuum cleaners on the market. Only few
minutes are required to collect the odors for huge volumes. The accessory
is made of 316L stainless steel grade, commonly used for medical devices.
It is thus easy to clean and durable.
We have chosen the Dyson and the Xiaomi vacuum cleaners that are light,
portable, long-lasting, affordable, and available anywhere in the world.
Getxent RASCO is used throughout the world in the areas of defense, health
and environment to detect prohibited goods in air and sea freight, search
for bacteria or bedbugs in rooms, and much more.

A. Sampling
Open the Getxent RASCO wallet and take the Getxent
RASCO accessory out.
If necessary, plug the plastic tubing in the push
connector.
Open the pouch containing non-impregnated Getxent
tubes and pick-up a Getxent tube with pliers.
With pliers, slide the Getxent tube in the Getxent
RASCO accessory until you feel it blocked inside.
Plug the Getxent RASCO accessory on the Dyson
vacuum cleaner; a click will make sure it is fastened
correctly.

RECOMMENDATIONS

Storage conditions: between -30°C and +50°C, clean and dry. Our best
recommendation is to store the Getxent RASCO accessory in the wallet
supplied, in a clean and dry place at room temperature.
Duration: The sampling duration depends on the odor concentration and the
volume of the area to be scanned. It follows the rule of thumb below:
Sampling duration (in seconds) = detection coefficient K x volume of the
area (in m3) / amount of odor (in kg)
The detection coefficient depends on the odor, the dog sensitivity or the
method and equipment used for GC-MS, typically, K=5-10. For example, a
sea freight container of 32m3 containing 1kg of explosives and considering
K=7,5 must be sampled during 240 seconds or 4 minutes.
Manipulation: Always wear gloves when handling Getxent RASCO accessory
and Getxent tubes. Before impregnation: ideally manipulate tubes in an
odor-free area with metal pliers and disposable gloves. Our best recommen-
dation is to use powder free nitrile gloves. Always minimize the time spent
handling the Getxent tubes and its exposure to the environment.
Cleaning: Use volatile organic solvent to clean the Getxent RASCO accesso-
ry and let it dry. Our best recommendation is to use ethanol 99%. The Getxent
RASCO accessory can be washed with tap water to remove dust, mud or any
particles then dried. Make sure the accessory is dry when re-packed. Avoid
the use of acids and bases that could damage the accessory. Avoid the use
of soaps or cleaning solutions as the contain chemicals and fragrances that
will pollute the accessory and interfere with the analysis.
Reuse: Getxent RASCO accessory can be reused after proper cleaning and
drying. Getxent tubes cannot be reused.
Elimination: Dispose Getxent tubes and packaging in the trash. If Getxent
tubes tubes or packaging are contaminated with a substance requiring
specific elimination conditions, comply with the legal requirements for
disposal of the contaminant.
Compatible models: Dyson V11 and V15, Xiaomi Mi Vacuum Cleaner G10.
