Oftentimes, aqueous samples collected contain varying amounts of suspended solids or sediment strictly due to either the source of the water being sampled or improper sampling techniques. In any circumstance, samples with high amounts of particulates or sediment have proven challenging to extract using EPA Method 3535 Solid Phase Extraction (SPE).

Laboratories which take in a high volume of aqueous samples will know that every sample is different. Samples can contain varying amounts of suspended particulates and/or sediment due to either the source of the water, or the collection technique. Still other samples may form precipitates under elevated pH conditions resulting in
emulsions. These types of samples have historically proven very challenging when using solid phase extraction (SPE).
