A unit of SRM 3185 consists of five 10 mL sealed borosilicate glass ampoules of solution.  The solution is prepared gravimetrically to contain a known mass fraction of nitrate dissolved in filtered (0.22 \u00b5m) water having a minimum resistivity of 18 megaohm centimeters. This data is public in the Certificate of Analysis for this material.", "identifier": "4765EE7CC5E7A396E0531A57068160031708", "keyword": ["Standard Reference Material", "SRM", "nitrate", "anion", "Advanced Materials"], "landingPage": "https://www-s.nist.gov/srmors/view_detail.cfm?srm=3185", "language": ["en"], "license": "https://www.nist.gov/open/license", "modified": "2016-09-06 00:00:00", "programCode": ["006:052"], "publisher": {"@type": "org:Organization", "name": "National Institute of Standards and Technology"}, "theme": ["Standards:Reference materials"], "title": "SRM 3185 Nitrate Anion (NO3-) Standard Solution"}
