Chromatography with higher pressure, smaller particles and higher temperature: a bioanalytical perspective

Area of Science:

• Analytical Chemistry
• Biochemistry
• Pharmacology

Background:

• Ultra-high-pressure liquid chromatography (UHPLC) and high-temperature liquid chromatography (HTLC) are increasingly utilized for analyzing biological fluids.
• These techniques aim to enhance throughput and reduce costs by optimizing analysis time.
• Key chromatographic parameters influencing efficiency and separation speed include particle size and temperature.

Purpose of the Study:

• To review the history and theoretical underpinnings of UHPLC and HTLC.
• To summarize advantages and limitations of sample preparation and detection systems (mass spectrometry, ultraviolet) in bioanalytical assays.
• To present a curated overview of selected bioanalytical applications of UHPLC and HTLC.

Main Methods:

• Review of existing literature on UHPLC and HTLC in bioanalysis.
• Analysis of theoretical principles governing chromatographic separation.
• Tabulation and discussion of sample preparation and detection methodologies.
• Compilation of diverse bioanalytical applications.

Main Results:

• UHPLC reduces analysis time via smaller particle sizes; HTLC achieves this through increased temperature.
• Both techniques present distinct advantages and limitations impacting method development.
• Effective sample preparation and appropriate detection systems (MS, UV) are crucial for successful bioanalysis.
• A range of bioanalytical applications demonstrate the utility of both UHPLC and HTLC.

Conclusions:

• UHPLC and HTLC are powerful tools for rapid and efficient bioanalytical assays.
• Understanding the theoretical basis and practical considerations of each technique is essential for optimal application.
• The choice of sample preparation and detection method significantly influences assay performance.
• Continued application and development of UHPLC and HTLC will advance biological fluid analysis.
