Combines ultra inert performance with low-bleed technology
J&W Ultra Low-Bleed (Q) GC/MS columns combine industry-leading Ultra Inert performance with Ultra Low-Bleed technology, delivering the new standard for MS column performance and productivity. 5Q columns provide exceptional peak symmetry and minimal column bleed enabling high sensitivity, mass spectral integrity and accurate quantitation for the most challenging, trace-level analytes. 5Q columns are also designed to optimize sample throughput with fast conditioning and outstanding durability even at high operating temperatures. As mass spectrometry continues to push the boundaries of sensitivity and speed, you need a column that can do the same. Agilent Ultra Low Bleed (Q) GC/MS columns are designed to ensure optimal delivery of your analytes to your quadrupoles.
Ultra Low Bleed Q columns are compatible with any GC/MS system to ensure a seamless fit.
Tools to help navigate to the best GC column choice for your application.

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 use of DB-5Q GC column provides faster conditioning, shorter analysis time, and greater convenience. It also results in lower column bleed, increased response, reduced baseline noise, improved sensitivity, ensuring smooth sample analysis.
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.
