Indoors air pollution:• Identification and characterisation of pollutants and odour sources• Assessment of treatment options• Preliminary toxicological impact assessment• Workplace air monitoring: sampling and analysis of dusts and chemical components (determination ofexposure limits), measurement of nanoparticles in ambient air, determination of the organic vapour cartridgeservice lifetime for respiration protection.• Probability calculation to make representative assessments of workplace exposure.<strong>Certech</strong>Emissions from materials<strong>Certech</strong> deals with research, development, testing and consulting in all aspects of emissions from materials.New requirements from end-users (low odour and emission products), new directives & regulations (forexample new OEM standards or construction products directive and its essential requirements on hygiene,health and the environment) have distinct influence on the market. They have generated a need for reliablelaboratory testing conditions. Combining its skills in sampling and analysis of air with its know how in materialtechnology, CERTECH has developed leading edge expertise in assessing and managing gaseous emissionsproduced by materials. It includes indoor air quality (IAQ), emissions from building or transport materials,migration phenomena and organoleptic contamination of packaging materials.Research is focused on the reduction of exposure related to different sources of pollutant by providing compound-specificdata on various organic sources, developing data useful to manufacturers and builders toassess potential product emissions and finally proposing new materials presenting a reduced rate of emissions(formulations or process modifications, new non-volatile additives, etc).Physico-chemical analysis (gas and liquid chromatography: VOC, sulphured compounds, amines, isocyanates,aldehydes and ketones, …, electronic nose) and sensory analyses (odour measurement bydynamic olfactometry, quantification based on intensity scale, qualitative description by expert panels andGC-MS-sniffing) are used to characterise gaseous pollutants.In order to face rapidly expanding demand, <strong>Certech</strong> proposes rapid screening of emissive materials anddeveloped products control for building materials, furniture and household products.<strong>Certech</strong> has been selected as the Belgian expert concerning the elaboration of the European StandardEN13725 “Air quality – Determination of odour concentration by dynamic olfactometry”, ISO 16000-5“Measurement strategy for volatile organic compounds (VOCs)” and ISO 16000-9, 10, 11 “Building products- Determination of the emission of volatile organic compounds”. It is currently involved in different committeeas expert (see 1.5).Polymer Technology<strong>Certech</strong> has developed leading expertise in the field of polymer technology. Services include adequateanalyses and measurements, problem solving, contract research, development of improved products andprocesses.Reverse engineering – Formulation:Reverse engineering (or deformulation) aims at identifying components of a sometimes complex assembly.<strong>Certech</strong> has a long experience in such type of analyses. Keys to success lie in a thorough knowledge ofmaterial and analytical science, and in the ability to plan and exploit numerous sophisticated investigationtechniques, as well as searching efficiently the literature for relevant and well-targeted information. <strong>Certech</strong>provides also services in the formulation of thermoplastics or thermosets based products according to customizedspecifications.7
