SLB-35ms Capillary GC Columns
Application: The 35% phenyl equivalent phase provides a higher polarity option compared to columns containing a lower phenyl content, resulting in a greater retention of polar analytes relative to non-polar compounds. Its selectivity is complementary when paired with SLB-5ms for applications that require dual-column confirmatory analysis, such as for environmental analytes (such as pesticides, PCBs, and herbicides). The low…

- Application: The 35% phenyl equivalent phase provides a higher polarity option compared to columns containing a lower phenyl content, resulting in a greater retention of polar analytes relative to non-polar compounds. Its selectivity is complementary when paired with SLB-5ms for applications that require dual-column confirmatory analysis, such as for environmental analytes (such as pesticides, PCBs, and herbicides). The low bleed characteristics, inertness, and durable nature make it a great column anywhere a low bleed intermediate polar column is required.
- USP Code: This column meets USP G42 requirements.
- Phase: Bonded and highly crosslinked; proprietary polymer virtually equivalent in polarity to poly(35% diphenyl/65% dimethyl siloxane)
- Temp. Limits: ≤0.32 mm I.D.: ambient to 350 °C (isothermal) or 360 °C (programmed)
- Temp. Limits: ≥0.53 mm I.D.: ambient to 330 °C (isothermal) or 340 °C (programmed)
A Comparison of Two Solid Phase Extraction Methods for the Analysis of Polyaromatic Hydrocarbons in Butter
This comparison shows that the Supelclean™ EZ-POP NP method produced better recoveries and lower background than direct SPE using a large silica cartridge for the analysis of PAHs from butter. When using EZ-POP NP, the final extract is clean enough for GC/MS analysis using the SLB®-35ms capillary column and single quadrupole instrument.
