Temperature significantly impacts liquid chromatography (LC) performance, affecting retention and selectivity. Recent advances in stable stationary phases and miniaturization drive renewed interest in using temperature for better control in chromatographic separations.

Area of Science:

  • Analytical Chemistry
  • Separation Science

Background:

  • Temperature is a critical factor influencing retention, selectivity, and column efficiency in liquid chromatography (LC).
  • Historically, limited use of temperature control in LC was due to stationary phase stability issues.
  • Miniaturization trends and development of temperature-stable stationary phases have increased interest in temperature's role.

Purpose of the Study:

  • To provide an overview of temperature's effects on retention and selectivity in chromatography.
  • To discuss instrumental requirements for temperature gradient elution.
  • To present applications using conventional and capillary columns.

Main Methods:

  • Review of existing literature on temperature effects in chromatography.
  • Discussion of instrumental considerations for temperature control and gradient elution.

  • Compilation of application examples.

    • Main Results:

    • Temperature profoundly influences chromatographic retention and selectivity, particularly in reversed-phase LC.
    • Temperature gradient elution offers advanced control over separation.
    • Successful applications demonstrated on both analytical and capillary scale columns.

    Conclusions:

    • Temperature is an underutilized but powerful parameter for optimizing chromatographic separations.
    • Modern stationary phases and instrumentation enable effective temperature control strategies.
    • Temperature manipulation is key for advancing miniaturized and conventional LC techniques.
