Pulp, paper and board - Determination of the Diisopropylnaphthalene (DIPN) content by solvent extraction

This European Standard describes a method for the determination of the content of diisopropylnaphthalene (DIPN) in paper, board and pulp by solvent extraction. The content of diisopropylnaphthalene (DIPN) is expressed as mg of total diisopropylnaphthalene DIPN isomers per kilogram of paper, board or pulp. This test method is appropriate for the quantitative determination of the content of diisopropylnaphthalene (DIPN) with a limit of determination of about 0,6 mg/kg.

Foreword
This European Standard (EN 14719:2005) has been prepared by Technical Committee CEN/TC 172 "Pulp, paper
and board", the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by February 2006, and conflicting national standards shall be withdrawn at the latest
by February 2006.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark,
Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,

1 Scope
This European Standard describes a method for the determination of the content of diisopropylnaphthalene (DIPN)
in paper, board and pulp by solvent extraction. The content of diisopropylnaphthalene (DIPN) is expressed as mg
of total diisopropylnaphthalene DIPN isomers per kilogram of paper, board or pulp. This test method is appropriate
for the quantitative determination of the content of diisopropylnaphthalene (DIPN) with a limit of determination of
about 0,6 mg/kg.
2 Principle
The content of total diisopropylnaphthalene (DIPN) is determined by solvent extraction of the paper, board or pulp
sample and analysed by gas chromatography with mass selective detection (GC-MS), using diethylnaphthalene as
an internal standard.
NOTE It may be worthwhile to state that diisopropylnaphthalene (DIPN) can be present as a contaminant in pulp, paper
and board. For the time being it cannot be avoided that diisopropylnaphthalene (DIPN) is present when using recovered fibres.
It may be present as either adsorbed onto the test piece or presen
