Single Element (1,000 and 10,000µg/mL)

Multiple quality control steps are observed when preparing our high purity standards for ICP and ICP/MS. We begin the purification of the starting materials. This purification is time consuming, but the final, high purity product is our goal. Stoichiometry is controlled during this process, allowing for the streamlining of the standardization checks later on. Typically, each starting material has a purity between 99.998% to 99.9999%. Other ingredients include pure metals, high purity acids and ASTM Type I water (18 megaohm). Our glassware is pre-cleaned and pipets, burets and flasks are class A certified with documentation. Our semi-micro mettler balance is calibrated regularly with NIST weights. Each batch of stock standard is carefully tested and recorded with lot number, test results via classical wet chemistry, standards used, and standardized to a tolerance of +/- 0.3% of specified value. These results are transferred to our certificate, which includes NIST-SRM information, sent with each standard. Most standards have a guaranteed shelf life of 18 months from the order date, with the exception of a few elements which have a guaranteed shelf life of 1 year from the order date.
