A Sensitive Assay for Detection of a Non-ionic Surfactant 

Triton X-100 is used in the sample purification steps of various materials as well as for cleaning apparatus in pharmaceutical manufacturing.  Due to the toxic nature of Triton X-100, a sensitive method for its detection and quantification is very important to identify any residual amounts.

This simple Isocratic Method may be used to verify residual amounts of this Surfactant have been removed from final material or from vital manufacturing equipment.

Note: Triton X-100 is one of the most widely used nonionic surfactants for lysing cells to extract protein and other cellular organelles. Triton X-100 (C₁₄H₂₂O(C₂H₄O)ₙ) has a hydrophilic polyethylene oxide chain and an aromatic hydrocarbon lipophilic or hydrophobic group. The hydrocarbon group is a 4-phenyl group.
