Certification & Traceability: This CRM was manufactured and certified under an ISO 9001, ISO/IEC 17025, and ISO Guide 34
quality management system. This CRM was prepared to the certifi ed concentrations shown above by gravimetric methods using singleelement concentrates that were certified using the “High Performa nce ICP-OES” protocol de veloped by NI ST and are directly tr aceable
to the NIST SRMs listed below. This solution was stabilized using high purity nitric acid (HNO
ohm deionized water. The balances used in the preparation of this CRM are calibrated regular ly with traceability t o NIST. All volumetric
dilutions are performed in Class A calibrated glassware. The certified concentrations were determined based upon gravimetric
procedures. Secondary verification of the certified concentration s was performed using ICP-OES t hat was calibrated and/or refer enced
against NIST SR Ms: 3151, 3101a, 310 7, 3104a, 3106, 3109a, 3108 , 3113, 3112a, 3114, 3126a, 3119a, 3124a, 3141a, 3129a , 3131a,
3132, 3152a, 3136, 3128, 3153a, 3158 and 3168a. The uncertainty associated with each certified concentration represents the
expanded uncertainty at the 95% confidence level using a coverage factor of k=2.
Instructions for Use: We recommend that the solution be thoroughly m ixed by repeated shak ing or swirling of the bottle imm ediately
prior to use. To achieve the highest accuracy the analyst shou ld: (1) use only pre-cleaned containers and transferw are, (2) not pipette
directly from the CRM’s original container, (3) use a minimum su b-samp le size of 50 0µL, (4) ma ke dilution s using calib r ated b alances or
certified volumetric clas s A flasks and pipettes, (5) dilu te with the same matrix as the original CRM, and (6) never pour used product
back into the original container. The solution should be kept tightly capped and stored under normal laboratory conditions. Do not freeze,
heat, or expose to direct sunlight. Minimize exposure to moisture or high humidity.
