What sampling media should I use?
Our preferred sampling method for both personal and static
samples is to use PTFE filters (Millipore 1.0um FALP02500) and IOM
samplers operating at 2L.min-1. PTFE filters are preferable over
GFA filters as there appears to be better and more reproducible
recovery of low level proteins from PTFEs. We can supply PFTE
filters if required, as well as appropriate kits for wipe sampling
and dust sampling.
If you would like to request any sampling media, please contact
Monitoring Service Manager.
How should I store the samples following sampling?
Following sampling, filters should be demounted from the
cassettes in a clean environment into tubes and capped ready for
transportation to HSL. Wipe samples should also be sent in capped
tubes. Appropriate tubes are available free of charge from HSL.
Samples should be sent for analysis as soon as possible after
sampling. If this is not the possible, please follow these
Short term storage (5 days maximum): Store in fridge until ready
for sending to HSL.
Long term storage: If there is a logistic reason for keeping
samples longer than 5 days after sampling, we recommended that they
are stored at -20C.
How do I send my samples to HSL if I am in the UK?

UK bank holiday should be avoided.
How do I send my samples to HSL if I am not in the UK?
Samples must be sent via a courier transporting samples under
