Sample Preparation for Chemical Analysis: Student Book

Product Details

This book examines operations performed to prepare a sample for analysis. With a focus on agricultural and natural materials such as fertilizer, students learn about sample management, analysis, and integrity through hands-on activities. One such activity allows students to determine the amount of vitamin C in the peel, pulp, and juice of an orange. Students become familiar with terms such as gross sample, bulk sample, aliquot, representative sample, sub-sample, and standard curve.
  • Includes background information and 10 investigations
  • 74 pages
  • Appropriate for college students and employed laboratory technicians
