The Thermo Scientific Pierce Standards are designed for a variety of applications, including sensitivity assessment, determination of digestion efficiency, chromatography assessment and/or as controls for sample analysis. Standards range from single component formulations to complex human-based digests. Each standard is provided with a Certificate of Analysis.
  • More choices—different standards to meet a variety of applications/needs
  • Stable—store for more than one year at the recommended temperature
  • Validated—all standards manufactured in an ISO 9001 facility measured and fully tested using Thermo Scientific Mass Spectrometers

Example selected reaction monitoring (SRM) of 500fg reserpine on a Thermo Scientific™ Vantage™ triple quadrupole mass spectrometer. Chromatogram of three 5 μL loop injections of 100 fg/μL Pierce™ Reserpine on a Hypersil GOLD aQ 2.1x20 mm Javelin column with isocratic 300 μL/min flow of 70% methanol: 30% water: 0.05% formic acid (upper panel).The SRM transitions monitored were 609.3-195.1 and 609.3-448.2 m/z with a 0.2 FWHM Q1 peak width (lower panel).
