Documentation

The paperwork is the product. These pages set out what we hold supply to, written so you can measure our claims against a standard that is not ours. Read them before you read anyone’s purity figure, including ours.

• Certificates of analysis

  What a certificate of analysis must contain, and how to tell a lot-specific certificate from a specimen one.

• Purity and identity

  Why HPLC purity and mass-spectrometry identity are two separate questions, and why a certificate needs both.

• Storage and handling

  How lyophilised peptide material is stored and shipped, and what is recorded against an account.

• Research use only

  What research-use-only means as a legal statement, who may hold an account, and what falls outside it.

• The Lot Standard

  The five conditions a lot must meet before it ships.
