Could toxic pesticides like DDT be responsible for the deaths of large numbers of lesser flamingos at Lake Nakuru, Kenya? While many organochlorine pesticides including DDT have been banned for decades in […]
a. Designing a sampling plan
Introduction This module introduces students to the topic of sample preparation using a variety of real-world examples from pharmaceutical analysis to environmental analysis. Liquid-liquid extraction, solid phase extraction, QuEChERS, derivatization in chromatography […]
[vc_row][vc_column icons_position=”left”][vc_column_text] Introduction This module provides a context for introducing fundamental techniques used in chemical analysis (spectrophotometry, atomic absorbance spectroscopy and ion selective electrodes) along with considerations about sampling and sample preservation. […]
Introduction This module provides a real world context for introducing fundamental quantitative techniques (pH, Ion Selective Electrodes, Ion chromatography, and Titrimery) used in chemical analysis of water samples. Using active learning pedagogy, […]
Students will learn to:
Assess the limitations of different sample types (e.g. urine, blood, hair)
Define various sampling strategies
Develop a rational sampling process
Students work through the decisions involved in developing a sampling plan in this activity.
In this activity, students are given an analysis problem and asked to develop plans for sampling and sample preparation.
