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):

Raman spectroscopy accurately identified corticosteroid structures in pharmaceutical preparations, even at trace levels. This method overcomes fluorescence issues using solvent extraction and HPLC separation for precise drug analysis.

Area of Science:

  • Analytical Chemistry
  • Spectroscopy
  • Pharmaceutical Analysis

Context:

  • Corticosteroids like fluocortolone are used in pharmaceutical preparations.
  • Excipients in formulations can cause fluorescence interference during analysis.
  • Accurate identification of drug substances is crucial for quality control.

Purpose:

  • To apply Raman spectroscopy for identifying corticosteroid molecular structures.
  • To develop a method for analyzing corticosteroids in complex pharmaceutical mixtures.
  • To overcome challenges associated with fluorescence and low sample quantities.

Summary:

  • Classical Raman spectroscopy was applied to fluocortolone and its esters.
  • Solvent extraction and High-Performance Liquid Chromatography (HPLC) were used to separate and purify the corticosteroids.
