SRM 1633c is a bituminous coal fly ash that was sieved through a nominal sieve opening of 74 \u00b5m (200 mesh) and then blended to assure homogeneity. A unit of SRM 1633c consists of 75 g of powdered material. This data is public in the Certificate of Analysis for this material.", "identifier": "4765EE7CC597A396E0531A57068160031628", "keyword": ["SRM", "Standard Reference Material", "coal fly ash", "sulfur", "mercury", "chlorine", "trace elements", "Energy"], "landingPage": "https://www-s.nist.gov/srmors/view_detail.cfm?srm=1633c", "language": ["en"], "license": "https://www.nist.gov/open/license", "modified": "2017-01-05 00:00:00", "programCode": ["006:052"], "publisher": {"@type": "org:Organization", "name": "National Institute of Standards and Technology"}, "theme": ["Standards:Reference materials"], "title": "SRM 1633c Trace Elements in Coal Fly Ash"}
