This paper reports on a Guideline (formerly Protocol) for
sampling and analysis of tars from biomass producer
gases. This Guideline was developed in a project in the
European Fifth Framework Programme with additional
partners from Switzerland and North America.
In this paper, the final outline of the Guideline is
given. This outline has been developed based on R&D work
performed by the project partners, which was not
performed in the EU project but was co-ordinated from it.
Highlights of the R&D work are shown in this paper, which
are the finding that formation and subsequent poor
separation of tar aerosols are a major cause of poor
collection efficiencies when sampling tars. The use of
glass frits and the use of a higher temperature in the
first impinger bottles avoid this problem of aerosol
Tar measurements performed by the Guideline have been
compared with tar measurements performed by the SPA
method. The two methods basically give the same result
for tar compounds ranging from phenol up to pyrene. For
larger compounds, a deviation is seen.
This paper does not contain the full text of the
Guideline. This full text is available on the Internet at
