DryLab 4 is the next generation UHPLC modeling software. With its comprehensive resolution and robustness mapping abilities, DryLab 4 offers an intuitive and visual solution for method development, optimization, trouble-shooting, robustness testing, and training.
DryLab 4 is the next generation (U)HPLC modeling software. With its comprehensive resolution and robustness mapping abilities, DryLab 4 offers an intuitive and visual software solution for method development, optimization, trouble-shooting, robustness testing, and training. DryLab 4’s 3D modeling capabilities and its multifactorial evaluation of flow rate, column dimensions, instrument parameters, and eluent composition in gradient and isocratic work, provide users with the tools to easily conform to Quality by Design standards. A further robustness evaluation helps users to find the robustness thresholds of their method, and determines which parameters exert the most influence on the critical resolution.
Our latest DryLab 4 feature, the Knowledge Management reporting tool, generates a complete method report, including the Design of Experiments, the 3D model, the robustness calculations, the comparison in retention times between the experimental and predicted outcomes, and all justifications for the method choices. This software tool encourages users to follows a QbD approach to method development, and helps ensure that the completed method conforms to these standards.

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.
