Fisher tfa
WebTrifluoroacetic acid (TFA) is commonly used in the manufacturing process to release synthesized peptides from solid-phase resins. TFA or acetate is also used during reversed-phase HPLC purification of peptides. TFA is manufactured using acetate and fluoride as precursors, and residual levels of these compounds may be present whenever TFA is used. WebSolid phase extraction (SPE) is a sample preparation technique often used by chromatographers prior to analysis. SPE is most often used to remove interfering compounds from a sample, although it can also be used to enrich/concentrate analytes of interest in the sample. SPE makes use of a solid phase material (there are many to …

For example, TFA is used with an acetonitrile gradient on a preparative reversed-phase HPLC column to purify synthetic peptides. Because TFA is toxic, its removal must be reliably measured in products intended for preclinical or clinical applications.
