A unit of SRM 3156 consists of five 10 mL sealed borosilicate glass ampoules of an acidified aqueous solution prepared gravimetrically to contain a known mass fraction of tellurium.  The solution contains hydrochloric acid at a volume fraction of approximately 10 %, which is equivalent to an amount of substance concentration (molarity) of approximately 1.2 mol/L. This data is public in the Certificate of Analysis for this material.", "identifier": "4765EE7CC5DDA396E0531A57068160031698", "keyword": ["tellurium", "pure materials", "cations", "metals", "single element solutions", "spectrometry", "Advanced Materials"], "landingPage": "https://www-s.nist.gov/srmors/view_detail.cfm?srm=3156", "language": ["en"], "license": "https://www.nist.gov/open/license", "modified": "2017-01-04 00:00:00", "programCode": ["006:052"], "publisher": {"@type": "org:Organization", "name": "National Institute of Standards and Technology"}, "theme": ["Standards:Reference materials"], "title": "SRM 3156 Tellurium (Te) Standard Solution Lot No. 140830"}
