Application Note 401:

US EPA Method 8270D specifies a procedure for the determination of semivolatiles in solid waste and ground water samples. The long list of analytes includes compounds of a variety of functionalities. A 0.25 μm df column is commonly used for this method, as it will allow for a short analysis time. However, the thin phase film of this dimension limits its sample capacity. An alternative choice is a 0.50 μm df column, which can accommodate higher concentrations and thus extend the calibration range.

L × I.D. 30 m × 0.25 mm, df 0.50 μm Application: The 5% phenyl equivalent phase provides a boiling point elution order with a slight increase in selectivity, especially for aromatic compounds. The low bleed characteristics, inertness, and durable nature make it the column of choice for environmental analytes (such as semivolatiles, pesticides, PCBs, and herbicides) or anywhere a low bleed non-polar column is required. ...
