MyMap nano-LC columns are a strong and reliable alternative to PepMap nano-LC columns, offering high sensitivity and excellent chromatographic performance for advanced proteomics workflows. With available inner diameters of 75 µm, 100 µm, and 150 µm and column lengths ranging from 50 mm up to 500 mm, they provide exceptional flexibility to match different nano- and micro-flow LC–MS applications. MyMap columns deliver outstanding resolution, sharp peak shapes, and high reproducibility — ideal for bottom-up proteomics, peptide mapping, biomarker discovery, and targeted MS quantification. Each column features integrated 1/16” male PEEK fingertight fittings on both inlet and outlet sides, ensuring a secure, leak-free, and dead-volume-free connection that prevents capillary slippage and guarantees stable operation under high pressure.

Packed with premium sub-2 µm C18 materials, MyMap columns provide ultrahigh efficiency and stable performance in long nano-LC gradients. The portfolio includes ReproSil-Pur 120 C18-AQ (1.9 µm) for strong retention of hydrophilic peptides, ReproSil Saphir 100 C18 (1.5 µm) for maximum efficiency and low bleed in MS analysis, and Exsil Mono 100 C18 (1.35–1.7 µm) based on monodisperse silica technology for exceptional batch-to-batch consistency. These materials ensure high plate counts, excellent peak capacity, and robust performance across complex peptide mixtures.
The hardware design minimizes extra-column dispersion and supports optimal ionization efficiency in nano-ESI MS workflows. The integrated fingertight PEEK system removes the need for tools or ferrules, simplifies installation, and ensures a highly stable and leak-free interface — critical for maintaining sensitivity and reducing carryover in LC–MS analyses.
MyMap columns are available in all combinations of 75 µm, 100 µm, and 150 µm IDs with lengths from 50 to 500 mm, allowing laboratories to tailor their setup to ultra-high-resolution gradients, high-throughput methods, or increased loading capacity. They are offered as single units, 4-packs, and 10-packs to support both routine analyses and intensive proteomics workflows. MyMap provides a powerful and versatile solution for any laboratory seeking dependable, high-performance nano- and micro-flow LC–MS separations.
