Development of a rapid test method to measure VOC from wood-based products for early prediction of the long-term emission behavior and quality control during the production process

Rapid test methods for VOC emissions are required for quality control and material development . Standardized test methods first deliver test results after 28 days. Therefore this project will develop a rapid test method within this project.

Background and Objective

Wood and wood-based products contain naturally occurring VOC (Volatile Organic Compounds), which emit during the life of a product. In consideration of further application of the product, data is required on the emission performance of wood and its processed products.

Currently, determination of VOC emissions is controlled by the standards prEN 16516, or rather, ISO 16000ff. The measurements proceed over 28 days in a test chamber delivering indications for long-term characteristics of VOC.

This measuring process takes too much time for production control and material development. Developing a suitable testing method for a rapid and reliable measurement of the emission behavior of VOC within few hours is consequently the aim of the project.

Approach

  • Development of a rapid test method
  • Investigation based on: Thermoextraction, µ-Chamber, gas analysis in conjunction with SPME-GC-FAIMS as a new measurement system for detection of VOC
  • Modification of process parameters and the reference value to determine the influence on measurement results
  • Testing of different wood species/ wood based products
  • Calculating correlations
  • Aim: equal and correlating values to the standard test method

Our Research Questions

  • How can a rapid test method be created?
  • What is the influence of testing parameters on emission behavior?
  • How can the inhomogeneity of wood be taken into consideration with regard to a suitable testing method?
  • What is the effect of product structure on the examination?
  • How can conclusions on the emission behavior of intermediate products to end products be drawn?
