When was the last time we sat down and had a good old chat about HPLC? It’s something I think about often—especially when I’m knee-deep in the lab. You know, HPLC (High-Performance Liquid Chromatography) has been my go-to for years, and if you’re anything like me, you’ve had your fair

So, there you have it—a bunch of reasons why your GC results might not add up to 100%. From incomplete detection to calibration issues, there are plenty of opportunities for those numbers to get thrown off. But now that you know what to look for, you’ll be better equipped to troubleshoot when things don’t go as planned.

If you ever find yourself in a bind, don’t hesitate to double-check your calibration, manage your baseline noise, and consider whether your sample might be decomposing or losing compounds before detection. Each of these factors plays a critical role in your final results.

Running blanks in HPLC might seem like an extra step, but it’s a step you can’t afford to skip. They ensure that your data is clean, reliable, and accurate, ultimately saving you time and boosting the credibility of your work. Whether it’s a mobile phase blank, a matrix blank, or an instrument blank, each one plays a vital role in your analysis. So next time you’re tempted to bypass the blank, ask yourself: is saving a few minutes really worth the risk to your results?

Choosing the right mobile phase in HPLC is like fine-tuning an instrument—it takes a little practice, but once you get it right, everything falls into place. By considering factors like polarity, pH, and buffer systems, you can significantly improve your chromatographic results.

I hope this article has provided some clarity on the topic. So, what do you think? Are you ready to optimize your mobile phase? If you have any further questions or need personalized advice, don’t hesitate to reach out. Let’s keep the conversation going!

At the end of the day, preparing HPLC standards isn’t rocket science—but it does require attention to detail. The key to success lies in consistency and accuracy, from the moment you weigh your standard to the final system suitability test before running your samples.

Have you found any particular tips or tricks that work best for you when preparing your standards? I’d love to hear your thoughts on what’s made your process more efficient. What do you think about recalibrating regularly—necessary or not?

Chromatography may sound technical, but it’s truly an everyday hero in science. Whether you’re interested in food safety, environmental protection, or pharmaceutical development, this technique is working behind the scenes to ensure the quality and safety of the products and environments we rely on. Chromatography’s ability to separate, analyze, and purify compounds makes it an indispensable tool across many industries.
