Evidential breath analyzer

National Metrology Institute Malaysia (NMIM) is preparing the ethanol standard solution in the concentration range of 40 mg/ 100ml to 80 mg/100 ml as standard for calibrating and verifying breath alcohol analyser. The standard solution is prepared gravimetrically and confirmed the concentration by GC-FID using non-IDMS exact matching method. The performance of this method has been demonstrated in international comparison and the result was in good agreement with the assigned reference value.
