2013 HPLC System Product Survey Results

By

High-performance/pressure liquid chromatography (HPLC) is, for many scientists, an essential chromatographic technique. HPLC systems used for the separation, identification, purification and quantification of various chemical and biochemical solutions are composed of a pump, a sample injector, a separation column, a detection unit, and a data-processor.

Top 6 Questions You Should Ask When Buying an HPLC System

  1. How flexible is the system? Can the system be optimized to meet your laboratory requirements?
  2. What tubes, vessels, and vials can it accommodate? Can components (such as additional detectors, valves, etc.) be upgraded in the future?
  3. Is the software easy to use and operate? Can a demo version be put in place to get a feel for how the software functions for your laboratory’s workflow?
  4. How is the system (not just components) qualified during installation to meet manufacturer performance expectations?
  5. Who provides the support and service for the product? Is it the manufacturer or a third party service group? If it is a third party service group, are they factory-trained?
  6. Finally, ask about the total cost of the purchase—not just the price of the product being installed— but the total cost of ownership, which includes price, service expectations, warranty, etc.
