Pentafluorobenzyl bromide (PFBBr) alkylating reagent, 5 g

Derivatize carboxylic acids, phenols and sulfonamides for GC analysis with electron capture detection (ECD) using Thermo Scientific™ Pentafluorobenzyl Bromide (PFBBr) Alkylation Reagent. Fast response times (∼20 minutes). Derivatives are highly sensitive to electron capture (EC), making them useful for detecting low levels of fatty acids. PFBBr has been used in the analysis of trace organics in asphalts and as a fingerprinting technique for determining asphalt contaminants in surface water.

Fast response times for the extraction alkylation method: ∽20 minutes
