    Definition "a technique used for determining the Mn ( IATE:1075862 ) and involves the determination of the molecular concentration of the end groups present on the polymer can lead to a value for the molecular weight" Reference "Based on: Council Regulation (EC) No 440/2008 laying down test methods pursuant to Regulation (EC) No 1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) CELEX:32008R0440/EN"
    Comment "Applicability: Mn up to 50000 (with decreasing reliability).For Mn < 20000, see also: vapour phase osmometry IATE:1291580 For Mn between 20000 - 200000, see also: Membrane osmometry IATE:156279 See also: Polymer end-group analysis: the determination of average molecular weight http://www.chem.fsu.edu/chemlab/chm3120l/polymermw/polymer_end_group_anal.pdf [20.1.2010]"
