1 Agilent J&W GC Columns For Environmental Applications MEASURE TRACE-LEVEL CONTAMINANTS AND MEET REGULATORY REQUIREMENTS WITH CONFIDENCE

2 Reliably and efficiently analyze increasingly small quantities of active solutes Every day, you are on the front lines in the battle to safeguard our natural resources from potentially harmful organic and inorganic contaminants in water, soil, air, and food. To succeed, you must be able to run a high volume of samples under increasingly heavy time and cost pressures. From testing volatile organic compounds (VOCs) in drinking water to quantifying semivolatile waterborne pollutants you simply cannot afford interferences or reduced sensitivity caused by column bleed or activity. For starters, having to redo a run or verify suspect analytes wastes valuable resources, hinders productivity, and hurts your bottom line. Even worse, unreliable results could have catastrophic implications in terms of environmental safety. The Agilent J&W GC column portfolio is designed and tested to help you achieve the lowest possible detection limits for difficult analytes. Backed by 0 years of GC column innovation and applications expertise, Agilent J&W GC columns deliver low column bleed and the lowest column activity for your sensitive, trace-level applications regardless of detector type. So you can confidently detect compounds at trace levels and comply with global regulations for continuous monitoring. Inside: the Agilent J&W GC column portfolio covering the very latest environmental applications Agilent J&W Ultra Inert GC columns for trace-level analysis... Agilent J&W GC columns for specific analysis types Agilent J&W DB-UI 0D Ultra Inert GC columns... Agilent J&W Select PAH and DB-EUPAH GC columns... Agilent J&W DB-UI GC columns...

3 Agilent J&W Ultra Inert GC columns Consistently analyze trace levels of pesticides, phenols, and other active compounds Flow path inertness isn t just vital to your analysis; it is also on the cutting edge of GC. That is why the Agilent J&W Ultra Inert GC column family pushes industry standards for consistent column inertness and exceptionally low column bleed, resulting in lower detection limits and more accurate data for diffi cult analytes. Every Agilent J&W Ultra Inert GC column is tested with the most demanding Ultra Inert test probe mixture in the industry, and we prove it with an individual performance summary sheet that is shipped with each column. Test probes in Agilent s Ultra Inert test probe mixture have low molecular weights, low boiling points, and no steric shielding of their active groups. These characteristics allow the probative portion of the test molecules to penetrate and fully interact with the stationary phase and column surface. So you can be sure you re getting all the benefits of column inertness, including: Minimal compound loss and degradation for more accurate quantitation Minimum peak tailing for active analytes Increased signal-to-noise for improved sensitivity at trace levels To complete your Ultra Inert GC fl ow path, choose Agilent GC/MS instruments as well as Agilent Ultra Inert Inlet liners. These liners deliver high trace-level sensitivity, accuracy, and reproducibility even when containing glass wool. Agilent Ultra Inert Inlet liners, great companion tools with the Agilent J&W Ultra Inert GC columns, are available in convenient 00 packs to meet the productivity demands of the environmental industry.

Agilent J&W High Efficiency Capillary GC columns Decrease your run times by 0% or more, without compromising resolution Agilent s high effi ciency GC column family has expanded to include both 0. mm id and 0. mm id columns. Agilent J&W High Effi ciency Capillary GC columns can reduce your sample run time by 0% or more (compared to conventional GC), so you can get the reliable results you need using the resources you have. They are ideal for applications that require faster run times, and offer: The flexibility to choose between helium and hydrogen carrier gases. You can stay with a helium carrier if you wish to simplify method development, or switch to a hydrogen carrier if faster analysis is desired. The ability to separate samples using less carrier gas, which can lead to longer intervals between cylinder changes, increased uptime, and a lower cost per sample. As an added benefi t, Agilent J&W High Effi ciency Capillary GC columns are compatible with all standardpressure capillary GC and GC/MS instruments without expensive high-pressure modifi cations.

Dibenzo[a,l]pyrene.. Dibenzo[a,e]pyrene.. Dibenzo[a,i]pyrene.. Dibenzo[a,h]pyrene Time In the chromatogram above, all + EU-regulated priority PAHs are well resolved with the Agilent J&W DB-EUPAH column. Challenging Benzo[b,k,j]fl uoranthene isomers are baseline resolved, allowing accurate quantitation of each isomer. Baseline resolution is also achieved for three critical pairs: benz[a]anthracene and cyclopenta[c,d]pyrene, cyclopenta[c,d]pyrene and chrysene, and indeno[,,-cd]pyrene and dibenzo[a,h]anthracene.

As a result, the signal-to-noise ratios are less than half of those achieved by the DB-EUPAH columns. The Rxi- column s excess bleed at higher temperatures makes trace-level detection diffi cult and unreliable for the four late-eluting dibenzopyrene isomers. With its higher upper temperature limit, superior thermal stability and greater column inertness, the Agilent J&W DB-EUPAH column improves peak shape and sensitivity. This translates to consistently lower detection limits a must for analyzing EU-priority PAHs.
