Description
|
SRM 1d - Limestone, ArgillaceousThis Standard Reference Material (SRM®) is intended primarily for use in evaluating chemical and instrumental methods of analysis of limestone and related materials. SRM 1d is composed of argillaceous limestone quarried in Putnam County, Indiana, USA. A unit of SRM 1d consists of a single bottle containing approximately 70 g of material of which 97 % passes a 75 μm (No. 200) sieve. keywords: geological materials , rock/sedimentary rock |
