Description
Calcium Standard for Flame Photometry (1000ppm) in H₂O is manufactured from ultra-pure salt and is tested by an ISO17025 Accredited Test Method (INAB Ref. 264T). The raw material used in this standard is assayed by titration and ICP-MS prior to manufacture. Separate CRM’s are used to control or calibrate the titration and ICP-MS respectively. This product is manufactured gravimetrically. Prior to bottling, the final product is tested and verified using ICP-MS and FAAS and it is certified using the gravimetric result, to a specification of ± 0.5%. The certified results are reported and certified in mg/l on the basis of weight.
