Analytical columns with inner diameters from 3.0 mm to 4.6 mm remain the most widely used formats in HPLC. They offer the ideal balance between resolution, robustness, and ease of use, making them the standard choice for method development, routine analysis, and a broad spectrum of applications across pharmaceuticals, life sciences, environmental testing, and food analysis.
Dr. Maisch analytical columns are packed with high-quality stationary phases that deliver sharp peaks, excellent reproducibility, and long lifetime. With their versatility and reliability, they form the backbone of modern analytical chromatography – robust enough for routine use and precise enough for demanding research.
The classic choice for routine HPLC. 4.6 mm ID columns allow higher flow rates, handle larger sample volumes, and deliver reliable performance across a wide range of applications.
Balancing sensitivity and solvent consumption, these mid-bore columns are ideal for labs seeking cost-effective performance without the need to switch to ultra-narrow systems.
Protect your analytical column and extend its lifetime. Guard columns trap contaminants and particulates before they reach the main column, ensuring consistent performance, reduced downtime, and lower overall running costs.
