IsoSciences

Internal standards are important for dependable analytical results. This is particularly true in LC/MS/MS analysis where lower detection limits and faster run times are always the goal. Because of varying injection volumes, ionization and retention times a true isotopically labeled internal standard allows for reliable data and to offset any instrument variation from sample to sample. IsoSciences has synthesized isotopically labeled internal standards for a wide variety of applications such as vitamins, steroids, metabolites and other molecules of chemical and biological interest.
