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.

Hewlett Packard 1090 - DAD not starting during a run
Having some problems with the DAD on a HP1090. In brief, when a sample is run, there are no signals saved from the DAD. I can see the trace on the screen and everything is moving as it should and everything says that the DAD is working fine. When a run starts however the DAD doesn't switch into "run" mode and stays as "pre-run". Does anyone have any suggestions how to get it to save the data? It used to work fine and one day it stopped and I've been given the task of fixing it. Advise this member.
