ISO 17025 quality system, scope extension in progress

Scope

  • Confirmation that the observed mass matches the expected sequence and modifications.
  • Detection of mass shifts from oxidation, deamidation, truncation, adducts or counter-ion.

Method

  • Electrospray ionization, Orbitrap high resolution mass spectrometry, LC inlet.
  • Deconvolution of the charge state envelope to the neutral mass.

Reported as

  • Observed and theoretical mass, mass error in ppm.
  • Deconvoluted spectrum and raw spectrum.

Sample

  • 1 vial, or powder.

Accreditation

Performed under the laboratory’s ISO/IEC 17025:2017 quality system. A2LA scope extension (certificate 6377.01) in progress.
