If you work with high-precision PCR, you know that choosing a good polymerase isn't everything. Errors in reaction conditions, primer design, or enzyme activation can ruin your experiment. In this article, we review the most common mistakes when using high-fidelity polymerases and how to avoid them with practical recommendations, including examples using Ampliqon's AQ97 High Fidelity DNA Polymerase.

Beyond choosing a good scale, maintaining its reliability depends on a tool that often goes unnoticed, but is absolutely essential: standard weights.

The choice of polymerase can make all the difference in your PCR results. In this post, we explain why high fidelity is key to avoiding errors and ensuring accurate DNA amplification.

This entry highlights the importance of inline filters and pre-columns in HPLC systems, components often considered accessories, but which can have a decisive impact on system stability and column lifespan. The text explains their function as a barrier against particles and contaminants, how to select them correctly based on pore size, and how to determine when replacement is necessary. It also delves into the role of pre-columns as key elements for preventing permanent contamination and protecting the main stationary phase.

This entry draws attention to an often-overlooked component of the HPLC system: the injector. Although it may seem like a routine mechanical step, its malfunction can lead to distorted peaks, noise in the chromatogram, or reproducibility problems. The text offers key recommendations to ensure clean, reproducible, and safe injection, from proper sample dissolution and filtration to the mechanical maintenance of the injector and its components.

The pump is one of the most critical components in an HPLC system: its job is to maintain a constant and precise flow of the mobile phase. When it fails, the symptoms can be as subtle as a slight noise in the baseline or as obvious as a pressure spike. In this post, we explain the differences between high- and low-pressure pumps, the most common signs of failure, and how good maintenance can prevent most problems. A practical read for those who know that the system's performance depends, to a large extent, on this small but vital component.

In this post, we discuss why mobile phase degassing is essential for achieving stable and accurate results in HPLC. We analyze the effects of dissolved gases on chromatographic analysis—such as baseline noise, retention variations, or bubbles in the system—and explain the most common techniques for removing them, from online degassing to the use of helium or sonication. We also include practical tips on solvent storage and best practices to avoid errors.

A guide designed for everyday laboratory use In this series, we help you identify and solve the most common HPLC problems, from the pump to the detector.
