Ensure accurate peak identification & quantification for GC analysis with J&W GC Columns.

Gas Chromatography (GC) columns are at the heart of the gas chromatograph and responsible for the separation process. GC is one of the most important and critical tools in analytical chemistry, because of its effectiveness, sensitivity and ease-of-use. GC columns contain a stationary phase, typically a polymeric material. It is through the interaction between the analytes and this stationary phase within the column that separation of the analyte into their molecular components can occur.

There are two types of GC columns: packed columns and capillary columns. Agilent offers over 3500 J&W GC columns. GC column types include fused-silica capillary wall-coated open tubular (WCOT), porous-layer open tubular (PLOT), and packed columns with the best inertness for acids/bases/mixed functional compounds, the lowest bleed levels and tightest column-to-column reproducibility.

The J&W 5Q columns combine industry-leading Ultra Inert performance with Ultra Low-Bleed technology, delivering the new standard for GC/MS column performance and productivity. Ultra Low Bleed Q columns are compatible with any GC/MS system to ensure a seamless fit.

The new 5Q columns were essentially a plug and play update to our aging HP 5MS UI columns. We have noticed a decrease in the amount of noise/bleed from the columns themselves during the high ramp temperature regions of our analytical pesticide method. This has allowed us to add additional analytes to our method for orthogonal analysis between LC and GC techniques and therefore increasing our confidence during reporting. The attached chromatogram shows chlordanes at 0.5 ppb in-vial on a cannabis concentrate-type matrix. We are very satisfied with the column's performance in regard to retention time shifting, overall bleed reduction, and reproducibility.

The broad portfolio of Agilent columns that are available is really a key aspect in developing methods. What is also very important is that we have a broad range of lengths, internal diameters and film thicknesses.

We have also been a long time user of the J&W Columns and we exclusively use those for high temp simulated distillation using the steel columns. Because of the nature of our work, we take the columns routinely every 50 minutes to about
