Enviro-Inert™ Technology: A New Generation In Environmental Testing
Why Is Reduced Activity Important?
Poor inertness as a result of increased column activity can lead to low acid/base sensitivity or analyte misidentification, causing incorrect data and big headaches! ZB-SemiVolatiles is designed with new Enviro-Inert technology to ensure:
- Inert, rugged performance without compromising separation
- Improved resolution of key critical pairs like Benzo[b]fluoranthene and Benzo[k]fluoranthene
- Better peak shapes and response for acids, amines, and PAHs
Enviro-Inert Technology Improves Inertness Without Changing Selectivity
You Spoke, You Tested, You Approved
Your input fueled the research and development of Zebron ZB-SemiVolatiles – the column specifically designed to overcome your EPA Method 8270D obstacles. Several environmental labs have verified real-world performance on ZB-SemiVolatiles:
- TestAmerica Laboratories, Inc. Buffalo
- Phoenix Environmental Laboratories, Inc.
- Other labs like yours!
“Zebron ZB-SemiVolatiles is a very stable and durable semi-volatile column. This has reduced TestAmerica’s downtime and increased our productivity, enabling us to better serve our clients’ needs.”

We QC Test for the SVOC Compounds You Analyze
We take the guesswork out of meeting method requirements by aggressively testing ZB-SemiVolatiles with two different test mixes. We incorporated troublesome analytes from your samples (Pyridine) and compounds in the 8270D tuning standard (DDT, Pentachlorophenol, and Benzidine) into our QC test, so you can be sure your column is ready to meet suitability requirements for the method.
