In part one of this series, we learned why water vapor is bad for volatile organic compound (VOC) analysis. In part two, we will explore ways we can optimize moisture control in the Purge and Trap (P&T) system.

What are the three worst enemies of low-level total organic carbon (TOC) analysis? Contamination, contamination, and contamination. Why stated three times? Because contamination can come from at least three different sources. The top three ways contamination can be inadvertently introduced into a TOC analyzer are reagents, laboratory glassware, and samples.

Analyzing volatile organic compounds (VOCs) is an essential part of environmental monitoring, flavor and fragrance analysis, and analysis in the pharmaceutical and petrochemical industries. Gas Chromatograph (GC) columns and detectors, namely Mass Spectrometers (MS), do not perform well in the presence of water. Before the sample is introduced to the GC, it must become a vapor.

For this reason, there are many samples, such as

With today’s blog, let’s get to know the employees of Teledyne Tekmar/Leeman Labs. The next person I I would like to introduce to you is Joe Barta.

Pharmaceutical production entails strict quality control and precise analytical testing methods. The United States Pharmacopeia (USP), European Pharmacopeia (EP) and Japanese Pharmacopeia (JP) have promoted TOC analysis as the analytical technique to verify that cleaning validation, purified water (PW) and water for intravenous injection (WFI) meet the high standards of the pharmaceutical industry.

Total Organic Carbon (TOC) is defined as the amount of carbon bound in an organic compound and is often used as a non-specific indicator of water quality or cleanliness of pharmaceutical manufacturing equipment.
