Description

Essentials in Modern HPLC Separations discusses the role of separation in high performance liquid chromatography (HPLC). This up-to-date reference systematically covers new developments in types and characteristics of stationary phases, mobile phases, and other factors of this technique that influence separation of compounds being analyzed. The volume also considers the selection process for stationary and mobile phases in relation to the molecules being separated and examined, as well as their matrices. The book includes a  section on the contemporary applications of HPLC, particularly the analysis of pharmaceutical and biological samples, food and beverages, environmental samples, and more.

Key Features

  • Discusses key parameters in HPLC separation
  • Describes interrelation between various HPLC features (solvent pressure, separation, detection)
  • Includes a large number of references

Readership

Analytical chemists in industry, research, and universities
