MASS SPECTROMETRY

Identity questions
deserve a defined method.

Discuss whether an LC–MS approach fits the information you need about your peptide or steroid sample. Confirm the method and its limitations with the laboratory.

FRAME THE QUESTION

What are you asking the analysis to establish?

Provide the claimed compound identity and relevant sample information. Ask the laboratory what the proposed method can support, which supporting output is available and what conclusions fall outside its scope.

  • State the claimed material identity and sample matrix
  • Confirm the analysis available for that material
  • Ask what evidence accompanies the reported result
  • Request additional work explicitly rather than assuming it is included

SAMPLE-LINKED RESULTS

Keep identity and other test results distinct.

Read each result against its own method, scope and units. A report should make it clear which work was performed and should not substitute one analytical question for another.
