Benefits

Have More Confidence in Your Development Process

Start development with well-chosen conditions

  • Choose a pH, solvent, and temperature that makes sense for your compound by predicting pKa, LogD, boiling point, and more.

Screen a full set of columns

  • Explore a range of chemistries by using the Column Selector to pick orthogonal columns and find the most effective retention mechanism.

Optimize methods with fewer experiments

  • Minimize experiments by using simulation to determine how the chromatogram would look under different conditions.
  • Find the optima in a few clicks.

Produce 3D models that fit reality

  • Optimize in 1D, 2D, or 3D.
  • Ensure the model fits your experiments by customizing the modelling equations.

Increase chances of method robustness

  • Get better chances of passing robustness tests by starting with a rational approach and visually understanding your design space.

Your dashboard for method optimization.

Find the best pH by predicting logD for each pH. Work within the green regions and avoid the red.

Peak tracking can get messy. Our peak-matching algorithm makes tracking UV peaks easier.

How (dis)similar are your columns? Use the Column Selector and pick the right columns with the help of radar graphs.

Reduce experiments by simulating chromatograms to see how the separation will look under new conditions.

How it Works

Rational, Reproducible Steps

Request a Consultation or Demo

  • 1 Predict the physicochemical properties of your compounds (pKa, logD, boiling point, and more). Use that information to select starting conditions.

Customer Reviews
“Without Method Selection Suite a lot of the students wouldn't understand chromatography very well. I’ve been using it in teaching Postgraduate courses for more than 10 years. They can investigate separation thoroughly in silico and then see the match with experimental labs. It gives them confidence in their abilities.”

Mel Euerby
University of Strathclyde, Visiting Professor

“We at Dow have used this tool extensively for small molecule separation and developed many methods for both in-process samples and final product.”

Binghe Gu
Dow Chemical Company

“Try ACD/Method Selection Suite—it saved me a lot of time and significantly reduced consumption of materials, while deepening my method development knowledge. You'll love it!”

Shabnam Sarshar
Project Manager, Medice

“My students say that the [Method Selection Suite] workshops are the highlight of the course. It’s always a pleasure to see the 'penny drop' as they suddenly understand how things they learned in theory are useful and relevant in real separations.”

Why Take a Software-Assisted Approach to Method Development?

Request a Consultation or Demo

Method development by trial and error can result in many wasted experiments. (And it’s incompatible with QbD principles.) By taking a rational approach, you can be confident of getting a good separation in a reasonable time, and justify your approach to others.

Software helps you with a logical approach by predicting physicochemical properties, calculating modelling equations, and optimizing. It also helps you share your results through shared databases, so your entire team can understand your project.

Improve Chromatographic Separations: Consider Mobile Phase pH & Analyte pKa

Chromatography aims to separate an analyte mixture into sharp, symmetrical, and well-resolved peaks for quantitative and qualitative analysis. To do this, it is crucial to understand ionization and the ionic form(s) of analytes at a given pH. The use of predictive software tools allows quick selection of optimal conditions and helps build robustness into methods from the start.
