Zebron ZB-5MSplus, GC Cap. Column 60 m x 0.25 mm x 0.25 µm, EA

Upgrade to Zebron from any 5 % phenyl or 5 % phenyl-arylene / 95 % dimethylpolysiloxane phase

Engineered for High Performance

Improved Inertness, Better Peak Shape, Low Bleed, and Aqueous Stability

Active sites on a GC column’s surface can result in analyte adsorption and degradation, negatively affecting peak shape and response. To reduce potential surface activity, Zebron ZB-5MSplus is designed with a rigorous fused silica deactivation process that improves inertness for troublesome compounds. Instantly achieve higher responses for active compounds compared to your current 5ms phase column, without changing your selectivity.

Melamine in Dog Food by GC-MS

Extraction Protocol:

1. Combine 0.5 g of homogenized dog food with 10 mL of DEA/Water/Acetonitrile (1:4:5) in a 15 mL centrifuge tube
2. Sonicate for 30 min
3. Centrifuge at 5000 rpm for 10 min
4. Transfer 100 µL of supernatant to an autosampler vial and evaporate to dryness using nitrogen gas
5. Reconstitute with 100 µL of Acetonitrile/Pyridine (1:1) and then derivatize using 100 µL BSTFA with 1 % TCMS at 70 °C for 45 min
