Unlock the power of HPLC columns from Macherey-Nagel with ESSLAB's expertise

At ESSLAB, we don't just supply products, we deliver analytical solutions backed by technical expertise and unwavering support.
The selection of the right column is a critical factor in ensuring accurate and reproducible results. The final packing of the column is paramount, especially when aiming for excellent batch-to-batch reproducibility. This becomes even more vital when attempting to reproduce methods over time, using replacement columns.


The significance of column packing: Why it matters
The success of any chromatographic analysis depends on the precision with which the final column is packed. Achieving excellence in this manufacturing process directly translates into reproducibility —crucial for researchers and analysts striving to replicate their methods weeks, months, or even years later with new replacement columns. Selection by matching up column physical specifications and chemistries might seem straightforward, but the key issue is how consistently these specifications are met during the manufacturing and packing processes.
Macherey-Nagel's commitment to quality: A solid foundation
Macherey-Nagel, a renowned name in chromatography, has set the standard for column manufacturing. Their commitment to stringent quality control and manufacturing processes ensures that each column batch meets the same high standards. This commitment extends to controlled column packing techniques, which play a key role in minimising variability - ensuring consistency in performance. The use of high-purity silica minimizes interference with analyte interactions, ensuring that retention times remain reproducible across different runs. Analysts can rely on the consistency of results, thanks to the excellent batch-to-batch reproducibility.
Peer-reviewed publications:
Columns that are supported by peer-reviewed publications add an additional layer of credibility to their performance claims. Published data provides independent verification of columns’ capabilities, and can serve as an invaluable reference for scientists developing new analytical methods. Publications also demonstrate that columns have been tested and validated by the scientific community.


Method development and optimization:
Reliable columns from reputable manufacturers simplify method development and optimise analytical processes. When working with well-characterized columns, scientists can focus on optimising other parameters of the chromatographic method, such as mobile phase composition, flow rates, and detection conditions, without concerns about column variability.
Regulatory compliance:
In highly regulated industries such as environmental and biopharmaceutical labs, using columns and other essential consumables from manufacturers with established, documented quality systems facilitates regulatory compliance.
