Enviro-Inert™ Technology: A New Generation In Environmental Testing

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

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.”

The opinions stated herein are solely those of the speaker and not necessarily those of any company or organization.

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.

*Requirement of 0.5 for 60 m x 0.25 mm x 0.25 µm and 10 m Guardian™ dimensions

Our QC test exposed poor performance for key compounds on competing columns. Enviro-Inert™ technology improves inertness, so you experience increased responses, lower limits of detection (LOD), and virtually no breakdown when using a ZB-SemiVolatiles GC column.

Conditions were the same for all columns tested. Comparative separations may not be representative of all applications.

Sample:

Analytes are 20 ppm in Dichloromethane
1. Pyridine
2. Pentachlorophenol
3. DFTPP
4. Benzidine
5. DDT
6. DDD

Pyridine is a very active amine and a good indicator for both column lifetime and sensitivity. Columns with higher initial peak responses can be expected to maintain performance over time. Additionally, higher responses allow you to run at lower levels of detection, improving the sensitivity of your analysis.

As part of our QC requirements, columns must meet minimum Pyridine and Pentachlorophenol responses. Each of the four competitor columns would have been failed by our QC department and would not have shipped to our customers.

Conditions were the same for all columns tested. Comparative separations are not representative of all applications.

Response Factor (RF)

RF is calculated by dividing peak height of analyte by peak of height of DFTPP as internal standard.

Enviro-Inert™ technology allows Zebron ZB-SemiVolatiles to provide improved productivity with shorter run times for SVOC methods, while maintaining resolution of key critical pairs.
