Teledyne Tekmar has a rich heritage that dates back to 1960. Since creating the first commercial purge and trap concentrator in 1975, Tekmar has been synonymous with innovative, quality products for Volatile Organic Compounds (VOC) analysis that increase the productivity of end user analytical laboratories worldwide. The Total Organic Carbon (TOC) product line has a reputation of meeting the needs of a diverse group of industries with pioneering technology and products for elemental analysis. In 2014, Teledyne Tekmar launched the AutoMate-Q40 Automated QuEChERS Sample Preparation Workstation for Semi-Volatile Organic Compounds (SVOC) for use in testing pesticide residues among other applications. (The AutoMate-Q40 has since been retired and is no longer being manufactured).
