We perform dialysis and elemental analysis of iron carbohydrate complexes.
We also evaluate active ingredient sameness of the generic and innovator products and for characterization of carbohydrate starting material and iron complexes:
Glycosyl Composition Analysis
Monosaccharide composition analysis (sugar residue analysis) quantifies the residues of polysaccharides, oligosaccharides or glycoproteins by GC-MS.
Glycosyl Linkage Analysis
Linkage analysis of polysaccharides and oligosaccharides is performed by partially methylated alditol acetate (PMAA) method to determine the linkage of monosaccharides and branching points.
The approximate molecular weights of polysaccharides are measured using size exclusion chromatography (SEC). The molecular weights of oligosaccharides are measured by MALDI-MS, either non-derivatized or after derivatization.
We provide high resolution high sensitivity mass spectrometry analysis using electrospray and nanospray ionization, Matrix Assisted Laser Desorption Ionization (MALDI) with time of flight (TOF) as well as iontrap and orbitrap mass analyzers.
