Precision for determination of nicotelline and nicotine in NIST SRM 1649b-Urban Dust and in Hivol filter sections. The NIST SRM served as a QC sample in analytical runs. The analysis of filter sections was performed to verify the uniformity of deposition of the analytes on the filter.

Analyte Measured Mean Precision (%RSD)
Nicotelline, SRM 1649b (N = 9) (in ng/g) 451 5.6
 Nicotelline, Hivol Filter Sections (N = 12) (in ngmL−1) 189 15
Nicotine, SRM 1649b (N = 9) (in ng/g) 52,800 8.4
 Nicotine, Hivol Filter Sections (N = 12) (in ngmL−1) 3,990 12.0

N: Number of samples; RSD: Relative Standard Deviation.
