Now you can get the benefits of exceptional efficiency ?more speed and more resolution ? on your conventional HPLC instruments.
Now you can get the benefits of exceptional efficiency - more speed and more resolution - on your conventional HPLC instruments. Poroshell 120 columns give you speed and resolution like a sub-2 μm column with up to 50% less back pressure - usually less than 400 bar.
In this video, Ron Majors and John Henderson demonstrate how to leverage Poroshell 120 on your conventional HPLC instrument, for optimal results. There are downloadable notes with chromatograms and exhibits, too.
Maximizing Cannabinoid Separation for Potency Testing with LC
April 7th 2025Researchers from the Department of Chemistry at Western Illinois University (Macomb, Illinois) conducted a study to optimize the separation of 18 cannabinoids for potency testing of hemp-based products, using liquid chromatography with a diode array detector (LC–DAD). As part of our monthlong series of articles pertaining to National Cannabis Awareness Month, LCGC International spoke to Liguo Song, the corresponding author of the paper stemming from this research, to discuss the study and its findings.
How Many Repetitions Do I Need? Caught Between Sound Statistics and Chromatographic Practice
April 7th 2025In chromatographic analysis, the number of repeated measurements is often limited due to time, cost, and sample availability constraints. It is therefore not uncommon for chromatographers to do a single measurement.
