Here at Teledyne LABS, we design, manufacture, and distribute products that help make this analysis easier for our customers. Five of these pain points are: Read More 0 Comments Click here to read/write comments Tags: VOC , Volatile Organic Compounds , drinking water , P&T , Purge and Trap One year after the East Palestine, Ohio, train derailment Posted by Amy Nutter on Mon, Mar 11, 2024 @ 02:57 PM Tweet It has been about one year since the Feb. 3, 2024, toxic train derailment in East Palestine, Ohio, where 20 cars carrying hazardous substances, including vinyl chloride, spilled onto the surrounding area. Vinyl chloride is a toxic material used in plastics production. Since then, a complete remediation of the Read More 0 Comments Click here to read/write comments Tags: VOC , vinyl chloride , P&T , Purge and Trap Determining Relevant Detection and Quantitation Limits Posted by Stephen Proffitt on Fri, Feb 09, 2024 @ 02:01 PM Tweet Quantitative analysis determines the concentration of a target analyte present in a test sample. Detection limits and quantitation limits are used to express the ability of the instrumentation and the accuracy of the analytical results. This blog provides a brief overview on guidelines and references for achieving applicable detection limits and reliable quantitation limits.

During this process, if the EPA designates these chemicals as High Priority Substances, they will undergo an extensive comprehensive study. These studies will be crucial to helping protect people from toxic exposure.
