Chromatography Column Selection

At Crawford, we’re not tied to a particular manufacturer and will recommend the most appropriate column for your situation. Whether you’re seeking to upgrade or replace an existing chromatography method, or in need of a published application, we can recommend the perfect column.

Using our experience, we will recommend the optimal column for the method and conditions. Our technical team are highly experienced method developers with backgrounds in high-throughput commercial labs. They understand how to develop and optimise a robust, reliable method for most applications—getting the best out of the most effective products.

HPLC Column Selection

We use a range of techniques to select the optimal HPLC column. Alongside our experience and applications, we have an in-house tool which compares data for nearly all common columns obtained via the independent USP database. We use this to find columns with both similar and diverse characteristics, depending on the variety of phases needed.

GC Column Selection

Using a combination of application data, retention indexes and our experience of method development we can find the correct column for your needs. Whether you’re using capillary, capillary PLOT or packed columns—we’ll recommend you the correct column for what you’re analysing.

Solid Phase Extraction (SPE)

Our technical team has extensive method development experience in SPE which we can use to recommend the optimal solution for your molecules and matrices. We will supply you with free sample cartridges and starting conditions to allow you to get going quickly.
