High-performance liquid chromatography (HPLC) confirms safe blood levels of slow-release bupivacaine nanoparticles.
Wastewater discharge permits under the Clean Water Act require dependable detection of volatile organic compounds, but water vapor transfer in purge and trap GC/MS systems can quietly undermine that data. This app note shows how the PerkinElmer GC 2400 and MS 2400, paired with the Teledyne LABS Tekmar Lumin P&T concentrator and AQUATek LVA autosampler, meet EPA Method 624.1 for VOCs in effluent wastewater while protecting the analytical system from water related interference.
