Abstract
European Pharmacopeia (EP) Method 2.2.44 “Total Organic Carbon in Water for Pharmaceutical Use” provides method and technique guidelines to the Pharmaceutical industry. These guidelines help to qualify the TOC analysis system through a System Suitability Test that compares the recovery of a Standard Solution (rs) of 0.500 ppmC sucrose (a relatively easy compound to oxidize) to a System Suitability Solution (rss) of 0.500 ppmC 1,4-benzoquinone (a diff

Abstract
US EPA Method 524.4 was used to determine the concentration of volatile organic compounds (VOCs) in drinking water. The Teledyne Tekmar Atomx XYZ purge and trap (P&T) VOC sample preparation system combined with a Thermo Scientific ISQ 7000 Mass Spectrometry (MS) system coupled with a Thermo Scientific TRACE 1310 Gas Chromatograph (GC) was used to create a working linear (r²) calibration curve, method detection limits (MDLs), initial demonstration of cap

Abstract
US EPA Method 524.2 was used to determine the concentration of volatile organic compounds (VOCs) in drinking water. This method is effective at concentrating trace levels of VOCs, however it can also transfer a significant amount of water vapor to the Gas Chromatograph/Mass Spectrometer (GC/MS) due to the four-minute desorb time recommendation. The Teledyne Tekmar Atomx XYZ purge and trap (P&T) VOC sample preparation system combined with a Thermo Scientific

Abstract
Hydrogen peroxide (H2O2) is used in numerous industries and has a variety of uses including sterilization, wastewater treatment, bleaching and as a propellant. The analysis of hydrogen peroxide for total organic carbon (TOC) content is a quality control (QC) test used to ensure purity. This application note will demonstrate that the Teledyne Tekmar Lotix TOC analyzer is robust enough to analyze the corrosive and acidic 3% hydrogen peroxide matrix and determine T

Abstract
Italian Legislative Decree 152/2006 was used to determine the concentration of volatile organic compounds (VOCs) in water matrices. The Teledyne Tekmar Atomx XYZ purge and trap (P&T) system along with a Thermo Scientific TRACE 1310 Gas Chromatograph (GC)/ISQ 7000 Mass Spectrometer (MS) with an Advanced Electron Ionization (AEI) Source was used to create a working linear regression (r²) calibration curve and method detection limits (MDLs) for target comp

Abstract
This application note demonstrates the Teledyne Tekmar Fusion UV/Persulfate analyzer’s ability to measure low levels of TOC in five popular bottled water brands. Bottled water samples varied in source and purification methods including: two natural aquifers, one vapor distilled, one reverse osmosis, and one two-stage microfiltration/UV light disinfection. All results had a 10% window of accuracy, based on a certified check standard concentration, and a pre

Abstract
US EPA Method 8260 was used to determine the concentration of volatile organic compounds (VOCs) in water samples. The Teledyne Tekmar Lumin purge and trap (P&T) concentrator, along with an AQUATek LVA liquid autosampler and an Agilent 7890B Gas Chromatograph (GC)/5977A Mass Spectrometer (MS) was used to create a working linear calibration curve and method detection limits (MDLs) for target compounds. This study will demonstrate the ability of the Lumin P&

US EPA Method 624 was used to determine the concentration of volatile organic compounds (VOCs) in wastewater samples. The Teledyne Tekmar Lumin purge and trap (P&T) concentrator along with an AQUATek LVA liquid autosampler and an Agilent 7890B Gas Chromatograph (GC)/5977A Mass Spectrometer (MS) was used to create a working linear calibration curve and method detection limits (MDLs) for target compounds.

Abstract
US EPA Method 524.3 was used to determine the concentration of volatile organic compounds (VOCs) in drinking water matrices. For this study, a Teledyne Tekmar Atomx XYZ purge and trap (P&T) system and Thermo Scientific TRACE 1310 Gas Chromatograph (GC)/ISQ LT Mass Spectrometer (MS) was used to create a working linear regression (r²) calibration curve, method detection limits (MDLs), and minimum reporting level (MRL) confirmation for target compounds.

Abstract
US EPA Method 8260, in conjunction with Methods 5030 and 5035, was used to determine the concentration of volatile organic compounds (VOCs) in water and soil matrices. For this study, a Teledyne Tekmar Atomx XYZ purge and trap (P&T) system and Thermo Scientific TRACE 1310 Gas Chromatograph (GC)/ISQ 7000 Mass Spectrometer (MS) with Advanced Electron Ionization (AEI) Source was used to create a working linear calibration curve and method detection limits (MDLs
