What makes an injection valve high-end?

The Spark (U)HPLC inspection valve is an equally good, if not better, alternative for other available high-end valves. This is the main conclusion of a transparant benchmark, conducted in collaboration with NHL Stenden University.

This white paper reveals the approach and technical results of the first systematic and thorough comparison made of high-end injection valves from different brands.

All you need to know about quality, performance and lifetime is in there!

  • How do the injection valves perform after 90,000 injections?
  • What differences in repeatability, carryover and wear occur?
  • Which valve scores the best?
