The LCGC Blog: Investigating (and Solving) Robustness Issues in HPLC
Not every method is as we would hope it would be. Some methods come to us in imperfect form and we have to live with them, while others are difficult separations and, by necessity, need to be developed using close control of several variables such as eluent pH, eluotropic strength, ionic strength, and so on.
VICI semi prep valve
The revised VICI Cheminert stream selection valves have an improved lifetime compared to the previous models and a pressure resistance of 100psi liq. The C45R valves have ports for 1/4" tubing and are vailable with 4, 6 or 8 selectable positions. They are available in manual versions, or on pneumatic or electric actuators. Learn more
LC Troubleshooting: Retention Time Drift – A Case Study
What should you do if your retention times drop from one injection to the next? John W. Dolan details his systematic approach to troubleshooting retention time drift, helping to quickly identify the problem source.
