The Availability Heuristic01:08

The Availability Heuristic

A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Area of Science:

  • Analytical Chemistry
  • Organic Chemistry

Context:

  • Accurate carbon determination is crucial in organic compound analysis.
  • Classical methods can be time-consuming and less precise for complex samples.

Purpose:

  • To develop a rapid, simple, and precise method for determining carbon content in organic compounds.
  • To overcome limitations of existing analytical techniques.

Summary:

  • A flash-combustion technique at 950-1050°C with oxygen sweep (80-100 ml/min) is presented.
  • Specialized fillings (cupric oxide, silvered alumina) and absorbents (magnesium perchlorate, manganese dioxide) handle combustion products.
  • Carbon dioxide is quantified via coulometry, enabling analysis of diverse compounds, including those with halogens, phosphorus, and metals.
  • Vanadium pentoxide is recommended as an oxidant for challenging samples like metal compounds with polynuclear rings.
