The within day variance, SSE, reflects the method variance, SSM. The day-to-day variance, SSF, reflects the sum of the method variance, SSM, and the sampling variance, SSS; SSF = SSM + SSS. 58. 19. 08333). 4 Fundamentals of Analytical Chemistry: 9th ed. 8-12. 1 × 104 / 454 = 15 lb; Since the seller took only a 5 lb sample and 15 lbs was needed, this is insufficient. 8-13. 36 for 8 samples = N The iterations converge at between 7 and 8 samples, so 8 should be taken for safety. 5 Fundamentals of Analytical Chemistry: 9th ed.

Chapter 8 Chapter 8 8-1. The sample size is in the micro range and the analyte level is in the trace range. Hence, the analysis is a micro analysis of a trace constituent. 8-2. The objective of the sampling step is to produce a homogeneous laboratory sample of a few hundred grams or less having a composition that is identical to the average composition of the bulk of the material being sampled.
