Description

General description

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:
