Every Neolight bottle and every Neolight Supply shipment carries a Certificate of Analysis (CoA) issued by our isotope-ratio mass-spectrometry lab.
What the CoA reports
Batch ID, production date, raw-water source, distillation runs performed, deuterium concentration in ppm, total dissolved solids after remineralisation, microbial panel, and storage recommendations.
Lab calibration
Our IRMS instruments are calibrated against international reference standards (V-SMOW2 and SLAP2). External cross-check samples are sent to a third-party lab quarterly.
Documentation pack for B2B buyers
