Tech Tip - 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’, whilst others are difficult separations and by necessity need to be developed using close control of several variables...

GC Column Conditioning

The required time and conditions actually depend upon the polarity of the stationary phase, the column length, internal diameter and thickness of the stationary phase film and the required upper operating temperature...

Ghost Peaks in Gradient HPLC

I guess we have all had the issue at some time or other. A blank injection of eluent (or a zero volume dummy injection) gives rise to discreet peaks on the chromatographic baseline which may interfere with analyte peaks...
