Safety rules
To safely operates the instrument, carefully follow
those indications.
1. Do not remove, for any reasons the enclosure
panels, without having turned o the instru-
ment and disconnected the power supply cable.
2. Always connect the instrument to a power
socket equipped with operational and ecient
grounding.
3. Do not operate the QB1 outdoor without hav-
ing provided protection from weather events
(rain, humidity etc).
4. Before starting any operation, nd a at and
stable accomodation for the QB1 with an ad-
equate sorrounding space for ventilation.
5. Operating temperature -10÷40°C
6. Max sampled gas temperature 45°C
7. Avoid contact and sampling of corrosive and
ammable compounds.
Precautions for humidity
Condense formation inside the sampler, reduces
the lifetime of some components, such as the pump
itself and dry gas meter as well.
Be sure the gases entering the QB1 are dry.
In case of presence of very wet/condensing gases
during the sampling, at the end of the operation,
allow the sampler to work with open air for at least
10 minutes.
The supply includes

♦QB1 sampler
♦Power cable
♦Sampling line quick connector
♦Hose barb for leak check
♦Operation quick guide

e thermometer shows the sampled gas condition
measured inside the dry gas meter.
e temperature is expressed in °C and it’s used to
normalize the volume considering the mean value
between the sampling starting and nal temperature
value.

Readings and normalization
of the volumes
e totalizer of the installed dry gas meter has a
resolution of 0.1 liters.
Before starting the sampling, take note of the vol-
ume and temperature values.
At the end of the operation, read again the volume
indicated and note it, with temperature value as
well.
Normalization of the volume can be done using the
following formula:
Vs = Vm . Pa . Tn
101.3 273 + Tgm
Where:
Vs [lt] = Normalized volume
Vm [lt] = Dry gas meter total volume
Pa [kPa] = Ambient pressure
Tn [K] = Normalization temperature
Tgm [°C]= Dry gas meter temperature

Flowrates denition
e sampling owrates depends on tubes used:
0.4 l/min - large tubes (600 mg)
1.0 l/min - jumbo tubes (1000 mg)
Set the owrate on LINE1 owmeter
Calculate dilution owrate
e owrate depends from humidity of duct fumes,
the ambient temperature and must avoid reaching
the condensation point in the sampled gas.
e graph on page 17 shows the dilution owrate
to set on QB1-D sampler.
1. FindtheRDvalue(dilutionratio)ndingonXaxis
the rw of duct gas (ratio by volume of the vapor
content e.g. 10% of vapor equals 0.1 of rw).
2. Findthecorrespondingcurveonambienttempera-
ture and read on Y axis the RD value.
3. Multipling RD value with sampling owrate
chosen, you nd the dilution owrate to use
Dilution sampler
QB1-D is a special version of the QB1 V2x5DC in
which the owrate of the secondary pump delivers
the dilution air instead of sampling.
is particular version is dedicated to VOCs
sampling in accordance with the EN13649 which
requires the dilution of the sample with, previously
cleaned and dehydrated, ambient air introduced in
the dilution chamber of the probe (HP1).
e dilution sampling oers the advantage of im-
proving the adsorbing eect on the sampling tube
thanks to the lower temperature and dehydrated gas
stream conditions.is allows also to use only one
charcoal tube and to greatly reduce the stripping
eect, usually due to high temperatures and water
presence.
To set the dilution rate, e.g. 1:4, regulate the total
sampling owrate, 1 lt/min for instance, and the
dilution owrate, 0.8 lt/min, the dierence of the
two values, 0.2 lt/min will be the resulting sampling
owrate.
e sampled volume will be given by the dierence
between the total sampled and the dilution volumes.
