Hey, I would like to ask about the product as with that specific group meaning Peptides in generel. My question is about the production of the peptides itself because HPLC purity is relative and vague atleast I believe considering this group. Though to be said I dont doubt your quality at all but I would really really like to know how you handle residues like TFA or PFAS in generel as it is known that certain synthesis like SPPS may leave residues due to useage of trifluoroacetic acid for example.
