Nicotine metabolites in human urine (frozen)

Description

• General description: A unit of Nicotine metabolites in human urine (SRM 3671) consists of three vials, each containing 10 mL of frozen human urine, one bottle of each of three levels. This standard reference material (SRM) was prepared from normal human urine collected from three different populations: nonsmokers without environmental exposure to tobacco smoke, nonsmokers with exposure to “secondhand” smoke, and smokers who smoke at least one pack of cigarettes per day.

• Application: Nicotine metabolites in human urine standard reference material (SRM) is intended primarily for use in evaluating the accuracy of procedures for the determination of nicotine metabolites in human urine. It is also intended for use in validating working or secondary reference materials.
• Preparation Note: The urine is shipped frozen (on dry ice) and, upon receipt, should be stored frozen until ready for use. Bottles of the SRM to be analyzed should be removed from the freezer and thawed to room temperature (20 °C to 25 °C). After the material is thawed to room temperature, it should be used immediately. The material should be swirled gently to mix before aliquots are withdrawn.
• Other Notes: SRM 3671 is intended for research use only. Details on expiration, storage, safety, usage, and source are provided in the NIST certificate Information on biomaterials, disposal, and transport is available in the SDS
