TLC for pharmaceutical analysis in resource limited countries

Area of Science:

• Analytical Chemistry
• Chromatography
• Pharmaceutical Analysis

Background:

• Product quality assessments are crucial, especially in resource-limited areas.
• Traditional chromatography methods like HPLC and GLC require extensive training and resources.
• Planar chromatography, specifically HPTLC, presents an alternative with unique advantages.

Purpose of the Study:

• To review the sustainability and advantages of planar chromatography for quality assessments.
• To highlight the suitability of HPTLC in resource-limited and field applications.
• To compare HPTLC with other chromatographic techniques like HPLC and GLC.

Main Methods:

• Review of existing literature on planar chromatography applications.
• Discussion of HPTLC's robustness, ease of use, and training requirements.
• Comparison of separation power and detection technologies between HPTLC, HPLC, and GLC.

Main Results:

• HPTLC demonstrates significant advantages in sustainability and robustness for quality assessments.
• Lower training requirements for HPTLC compared to HPLC enable broader accessibility.
• Successful applications of planar chromatography in resource-limited countries are documented.

Conclusions:

• HPTLC is a viable and effective technique for product quality assessment in resource-limited settings.
• Despite lower separation power than column methods, HPTLC is adequate for analyzing finished pharmaceutical products with few active ingredients.
• The accessibility and practicality of HPTLC support its use in field applications and developing regions.
