The Sample Train
The sample ''train'' is the name given to the combination
of a pump, flexible tube and sampling device when
connected together. It does not matter what kind of
sampling device is attached to the pump as there are no specific terms for individual setups. The figures
below give examples of sampling trains. Additionally
the figure on the right illustrates the sample train during
the process of calibration.

Sample Train Check List
•
Ensure the pump is fully charged and in good condition.
• Treat the filter media with care.
• Calibrate in a clean area to avoid contamination of the sample media.
• Ensure the flow rate is set at the correct level required for the sampling device or methodology.
• Ensure that all connections are leakproof and secure.
• Mount the sampler in the “breathing zone” - a 30cm hemisphere centred around the mouth.
• Ensure the flexible tube is not left to hang free and become a hazard.
And Finally...
• Always note the sample start and finish time.
• Don’t forget to index the sample media, person sampled, time, date and location, together, preferably on a
form.
• Remember - The result is only as good as the sample taken.
