HPLC Varian ProStar
HPLC je oblik kromatografije na stupcu koji se često koristi u analitičkoj kemiji. Ponekad se u literaturi može naći i naziv "Tekućinska kromatografija pod visokim tlakom" (engl. High pressure liquid chromatography - HPLC). HPLC se koristi za razdvajanje komponenti iz smjese na osnovi kemijskih interakcija između tvari koja se analizira i stacionarne faze u stupcu.

Princip rada i mjerna tehnika
Gradient pumps offer selectable one-, two-, or four-stroke proportioning is available to optimize gradient precision on long, shallow gradients while minimizing gradient delay volume on steep, fast gradients. Reliable results -- Intelligent design, including electronic flow and in-line, high-speed proportioning valves, assures accurate and reproducible results. GLP compliance -- Run-and-error logs maintain a complete audit trail of operating parameters, set points, errors, and faults. Built-in automations -- Up to five methods can be built and stored at the pump. Choose the appropriate method with a single keystroke.
