Description
|
This Standard Reference Material (SRM) is intended primarily for validating analytical methods and measurements for the determination of arsenic species in human urine. A unit of SRM 3669 consists of five pouches each containing a vial of arsenic species in frozen human urine at elevated levels. keywords: Biological material, Body fluid, Urine, Speciation analysis, Arsenic speciation
|
Package |
Each vial contains nominally 1.5 mL of urine. SRM 3669 is shipped on dry ice, and it should be stored at –80 °C until use. |
