PRESTATION : Costs - Air Inter-Laboratory Comparisons (ILC): sampling and analyses For more than 25 years, Ineris has been organising Inter-Laboratory Comparisons (ILC) to improve sampling and analysis practices in the field of air: stack emissions, indoor air and workplace air. Inter-Laboratory comparisons enable laboratories to meet the accreditation requirement of monitoring their performance by comparing it with the results of other laboratories. ILC on testing bench On-line samplings and analysesCompare sampling practices:- test the conformity of materials and practices- identify results dispersion sources- propose improvements to benchmarks.Estimate individual performance level of participants and measurement methods. Analysis laboratory AnalysesImprove the quality of analytical method implementation.Allow participants to judge the accuracy of their results in relation to reference values or assigned values and evaluate theirrepeatability.Obtain a satisfactory comparability of results coming from different laboratories responsible for monitoring releasesinto air. Stack emissions into the atmosphere Capacity to accommodate 12 participants simultaneously.Real matrices: atmospheres generated from combustion gas (natural gas, light fuel-oil or biomass), with or without dust, that can be heated, moistened or spiked with various pollutants.ILC in the testing bench:Evaluation of automatic methods (on-line): NOx , CO, CO2, O2, CH4, total COV, non-methane COV.Evaluation of manual methods (sampling): total dust, HCl, NH3, SO2, humidity. Analytical ILC:HCl, NH3, SO2, HF, HAP, metals.Gas and particle phase: absorption solution, filters, resins,… exposed to combustion gases produced in the testing bench.Dust by gravimetry*: filter and rinsing solution. Indoor air Exposure chamber Analytical ILC (diffusive sampling supports): FormaldehydeBTEX (benzène, toluene*, ethylbenzene*, xylenes*)Preparation of testing materials in an exposure chamber to simulate a real matrix.Atmospheres generated in controlled environmental conditions.Exposre concentrations close to indoor air guide values. Workplace air* Concentration levels between 1 and 200% of OEL (French Occupational Exposure Levels).Analytical ILC:Metals (Cd, Cr, Cu, Ni, Pb) - MercuryInorganic acids (HF, HBr, HCl, H3PO4, HNO3, H2SO4)BTEX (benzene, toluene, ethyl benzene, xylenes)Acetaldehyde, formaldehydeMethanol - Ammonia Inter-Laboratories Comparisons 2026 - COSTS Documents relating to the tests can be downloaded from the Ineris website dedicated to Interlaboratory Comparisons:: https://comparaisons-interlaboratoires.ineris.fr Ineris accreditation scope for the organization of CIL is available on::http://www.cofrac.frCOFRAC certificate n°1-2291.
