Low Flow HPLC Columns | Thermo Fisher Scientific

Overview

Enhanced performance of low-flow LC-MS and HPLC separations

Low-flow chromatography is ideal when detailed sample information is required from small sample volumes, especially for bottom-up and top-down proteomics research. Compared with analytical flow LC-MS (>100 µL/min), the signal with low-flow (<100 µL/min) can be many times higher. Low-flow columns—also known as micro, nano, and capillary columns—have a smaller diameter compared to analytical columns.

Thermo Scientific nano-, capillary-, and micro-flow columns offer excellent sensitivity and resolution in easy-to-use formats:

Thermo Scientific EASY-Spray HPLC Columns
Thermo Scientific double nanoViper HPLC Columns
Thermo Scientific μPAC Neo HPLC Columns

All HPLC and UHPLC columns

Low-flow HPLC columns powered with technology that's beyond brilliant

Learn more about the power of Thermo Scientific low-flow HPLC columns and discover column designs that ensure near zero-dead volume connections to give you confidence in your data quality.

µPAC HPLC column technology is a silicon revolution in chromatography

Our patented technology overcomes the physical limitations of packed bed LC columns. It reduces peak dispersion which leads to better separation. Furthermore, this unique technology increase data reproducibility and decrease costs as these columns are highly robust and reliable.

μPAC Neo High Throughput Columns for single-cell to comprehensive proteomic applications

Improve your chromatography and analyze hundreds of samples per day, day after day, and do it without sacrificing performance and reproducibility.
