Improving, Retaining, and Separating Polar Compounds Using Chromatographic Techniques
Separating and retaining polar compounds are significant challenges in chromatography. Here, we explore the key technical considerations and solutions for effectively handling these compounds, focusing on advanced chromatographic techniques and column technologies. What Are Polar Compounds? Polar compounds are essential in biological processes, drug design, and industrial applications due to their ability to interact with…

What is microflow LC?
What are the differences between micro-scale and conventional LC? Microflow (a.k.a. microscale) LC has been widely applied to proteomic research for years. Recently, as microflow LC-MS systems continue to evolve, more and more laboratories in various fields are weighing the implications of applying this small-is-beautiful technology. In this and my next two blog posts, I will discuss...
In Beverly, the Shoe Fits for Bioanalysis!
This past May, many of the nation’s leading bioanalysts gathered in New England to share ideas and explore the latest advances in mass spectrometry, liquid chromatography, and sample preparation for large molecule quantification. At Waters’ semi-annual bioanalysis workshop, scientists from across the U.S. trained on the latest mass spectrometry instrumentation at our demonstration center in...
Oligonucleotide Therapeutics on the Rise… Again
Oligonucleotide drug development has seen its share of ups and downs over the past 20 years – but why? The promise of antisense oligonucleotides (ASOs) and later small interfering oligonucleotides (siRNAs) as therapeutics that can “dial down” or even “turn off” the expression of specific genes/proteins (“gene silencing”) remains high, yet companies dedicated to their...
What do you get if you combine mass spectrometry with 5000 cups of beer, 1000 glasses of wine, and 600 servings of mac ‘n’ cheese?
… A successful ASMS 2016! ASMS is definitely one of the highlights of our year and here at Waters we are only just recovering from this year’s event and, can you believe it, starting to think about next year already. It’s funny because whenever I travel to America my children are always slightly suspicious that...
Binary vs. Quaternary Pumps: High Pressure Mixing vs. Low Pressure Mixing
Welcome to the next installment in my series on binary vs. quaternary pumps for liquid chromatography! In my previous post, I discussed how gradients are created as well as the importance of having accuracy and precision in your gradient. Today I am going to talk about what happens after all that — specifically, mixing. After chromatographic...
Do You See What We See? Mass Spectrometry Imaging is Revealing Insights in Biomedical Research
The spatial distribution of molecular species in a sample can provide a wealth of information about biological, chemical and physiological processes. Mass spectrometry (MS) imaging is a rapidly developing research technique that enables specific measurement of molecular targets at complex surfaces. This direct-from-sample analytical technique provides researchers with the information needed to quickly and objectively...
