How to choose a column ?

• Suitability for a specific application
• The column must do the job
• If already using a different column the new column should provide a benefit in performance or durability
• Reproducibility of the result from column to column and Lot to Lot
•  Reliable performance
• Stability & Life time of the column
• Less column changes will cause less instrument down time and therefore more sample can be run
• Compliance with official methods that might need to be followed
•  In case the customer needs to follow official methods like Pharmacopoeia, EPA, DIN or other local
• LC/MS suitability (for LC/MS user)
