This 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. NIST-3671 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. A unit of NIST-3671 consists of three vials, each containing 10 mL of frozen human urine, one bottle each of three levels. /// Sample value(s) - please ask for current certificate.
