Excitement abounds in the Teledyne Tekmar labs as the Versa headspace autosampler continues to meet the challenges of an ever-changing environmental science world. Its big brother, the HT3, started this excitement when it successfully met the challenge to detect low levels of 1,4-dioxane, bromoform, acrylonitrile and vinyl chloride in water following new environmental guidance from Korea and the Asian market.
The US EPA hosted a technical workshop on analytical chemical methods for hydraulic fracturing on February 25th in Research Triangle Park, NC. The goal of these workshops is to gather together stakeholders, technical experts, and EPA representatives to get updates on the progress of the EPA’s testing with regards to hydraulic fracturing. It also serves as a forum to discuss best testing practices and methodologies for this area. Teledyne Tekmar was privileged to participate as a speaker and participant in the round table panel discussions that coincided with the workshop.

Automated sample preparation is built upon making instruments easier to use, faster, and more efficient. More recent features to purge and trap systems like mass flow controllers and variable volume standard addition, give more method flexibility than legacy products. The 27 mL syringe on our Atomx VOC sample prep system allows for dilution of high level samples as well as automated methanol extractions.
You have successfully installed your TOC analyzer and, as suggested, you run a “Leak Check” prior to starting your analysis. The leak check fails, so you tighten everything, perform another leak check, and still, the instrument does not pass. Without a plan of attack, this can be frustrating and time consuming. Fortunately, there are some troubleshooting techniques that can help.
