This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO supplies Gadolinium(III) sulfate octahydrate (CAS 13450-87-8), a certified reference material (molecular formula GdO4SH2O, MW 271.32 g/mol) for analytical method development and quality control.
Owing to a sulfone group, Gadolinium(III) sulfate octahydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
As a certified reference material (CRM), Gadolinium(III) sulfate octahydrate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
