Domestic sludge

Description

• General description: One unit of SRM 2781 consists of a bottle containing 40 g of dried and pulverized domestic sludge. For more information, please refer to the SDS and COA.SRM 2781_certSRM 2781_SDS
• Application: Domestic sludge Standard Reference Material (SRM) is intended primarily for the evaluation of methods employed in analyzing sludges and other materials of a similar matrix.
• Features and Benefits: Accompanied with certified mass fraction values for elements that are metrologically traceable to the SI unit for mass expressed as percentages or milligrams per kilogram. Reference mass fraction values are provided, along with both elemental and organic constituents, which are noncertified values serving as the best estimates of true values. Information mass fraction values are also provided for organic constituents. Expiration details, storage, and instructions for use are provided on the NIST certificate.
• Other Notes: Certified for the analytes listed below.Arsenic (As), Nitrogen (N), Cadmium (Cd), Chromium (Cr), Copper (Cu), Lead (Pb), Mercury (Hg), Molybdenum (Mo), Nickel (Ni), Selenium (Se), Silver (Ag), Zinc (Zn)Reference/Informational value is provided for the following analytes.Beryllium (Be), Aluminum (Al), Calcium (Ca), Iron (Fe), Magnesium (Mg), Phosphorus (P), Potassium (K), Silicon (Si), Sodium (Na), Titanium (Ti), 1,3,4,6,7,8-Hexahydro-4,6,6,7,8,8-hexa-methyl-cyclopenta-(γ)-2-benzopyran (HHCB), 7-Acetyl-1,1,3,4,4,6-hexamethyltetralin (AHTN), 5-Acetyl-1,1,2,6-tetramethyl-3-isopropylindan (ATII), 4-Acetyl-1,1-dimethyl-6-tert-butylindan (ADBI), 6-Acetyl-1,1,2,3,3,5-hexamethylindan (AHMI), Perfluorohexanoic Acid (PFHxA), Perfluoroheptanoic Acid (PFHpA), Perfluorooctanoic Acid (PFOA), Perfluorohexanesulfonic Acid (PFHxS), Perfluorooctanesulfonic Acid (PFOS), Perfluorooctane Sulfonamide (PFOSA), γ-hexabromocyclododecane (γ-HBCD), γ-hexabromocyclododecane (γ-HBCD), γ-hexabromocyclododecane (γ-HBCD), Aluminum (Al), Barium (Ba), Cadmium (Cd), Calcium (Ca), Chromium (Cr), Copper (Cu), Iron (Fe), Lead (Pb), Magnesium (Mg), Manganese (Mn), Nickel (Ni), Silver (Ag), Vanadium (V), Zinc (Zn), Perfluorononanoic Acid (PFNA), Perfluorodecanoic Acid (PFDA)See certificate for values and more details at nist.gov/SRM.
