Application Report 391

US EPA Method 8270D specifies a procedure for the determination of semivolatiles in solid wastes and ground waters. The suitability of the SLB-5ms for the separation of 72 analytes (plus eight surrogates and six internal standards) specified in the method is demonstrated. The optimized chromatogram obtained on the SLB-5ms is presented.

L × I.D. 30 m × 0.25 mm, df 0.25 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. ...
