Introduction
Part of OPEN BIO Deliverable N°3.8 is used as starting point for the description given in this document.
Bio-based products from forestry and agriculture have a long history of application, such as paper, board
and various chemicals and materials. Over the last decades new bio-based products have emerged in the
market. Some of the reasons for the increased interest lie in the bio-based products’ benefits in relation
to the depletion of fossil resources and climate change. Bio-based products may also provide additional
product functionalities. This has triggered a wave of innovation with the development of knowledge and
technologies allowing new transformation processes and product development.
Acknowledging the need for common standards for bio-based products, the European Commission issued
1)
Mandate M/492 , resulting in a series of standards developed by CEN/TC 411, with a focus on bio-based
products other than food, feed and biomass for energy applications.
The standards of CEN/TC 411 “Bio-based products” provide a common basis on the following aspects:
— Common terminology
— Bio-based content determination
— Life Cycle Assessment (LCA)
— Sustainability aspects
— Declaration tools
It is important to understand what the term bio-based product covers and how it is being used. The term
‘bio-based’ means 'derived from biomass'. Bio-based products (bottles, insulation materials, wood and
wood products, paper solvents, chemical intermediates, composite materials, etc.) are products which
are wholly or partly derived from biomass. It is essential to characterize the amount of biomass contained
in the product by, for instance, its bio-based content or bio-based carbon content.
The bio-based content of a product does not provide information on its environmental impact or
sustainability, which may be assessed through LCA and sustainability criteria. In addition, transparent
and unambiguous communication within bio-based value chains is facilitated by a harmonized
framework for certification and declaration.
This document has been developed with the aim to specify the method for the determination of oxygen
content in bio-based products using an elemental analyser. This document provides the reference test
methods for laboratories, producers, suppliers and purchasers of bio-based product materials and
products. It may be also useful for authorities and inspection organizations.
Part of the research leading to this document has been performed under the European Union Seventh
Framework Programme OpenBio (see biobasedeconomy.eu)
) A mandate is a standardization task embedded in European trade laws. Mandate M/492 is addressed to the
European Standardization bodies, CEN, CENELEC and ETSI, for the development of horizontal European Standards
for bio-based products.
1 Scope
This document provides an overview of existing applications of isotope ratio analysis of carbon,
hydrogen, oxygen and nitrogen that are relevant to the analysis of bio-based feedstocks, products and
production processes.
The stable isotope ratios of carbon, hydrogen, oxygen and nitrogen can be used to obtain information
about the origin of bio-based feedstock and characteristics of production processes of bio-based
products. However, no or limited attention for the use of the elements nitrogen and sulphur is given in
this document due to the fact that these applications are not yet available.

4 Direct isotopic measurements
As described previously in Direct Automation OPEN BIO Deliverable N°3.7, isotopic measurements are
performed using an Isotope Ratio Mass Spectrometer (IRMS). In order to test various samples (solids,
liquids), automatic elemental analysers (EA)are connected to isotope ratio mass spectrometer for whole
sample material for Bulk Stable Isotope Analysis (BSIA). This methodology is easy to operate, carries out
fast analyses (few minutes), and has relative low cost enabling multi isotopic determinations. EA-IRMS is
very suitable for regular authenticity controls of pure raw materials. Usually isotopic instruments are
able to give the isotopic values of all organic elements contained in the samples.
Isotopic ratio mass spectrometer can also be connected to chromatography devices (separate methods)
combustion or pyrolysis interface for Compound Specific Isotope Analysis (CSIA).Two different processes
are available(GC-C/P-IRMS or LC-co-IRMS) depending on the molecules to be investigated. This approach
is extremely appropriate for regular authenticity control of natural mixture samples (flavour, ho
