HI!,IīVE BEEN HAVING PROBLEMS WITH PERASURE IN MY COLUMN TSK, AND I CHANGED IT FOR A NEW KROMASIL. AFTER ONE DAY OF WORK IT HAS ONLY HALF OF THE PREASURE THAT IT HAS TO GOT. I TRYED BUBLES OF AIR, SOMICATE THE FILTER OF MOBIL PHASE, AND LOOKED FOR LOST OF DISOLVENT, BUT I CANīT FIND WHAT IS THE PROBLEM.THE PUMPS GIVE THE RIGHT FLOW . IīVE BEEN WORKING WITH KH2PO4 PH 7 /AcN AT FLOWS OF 1.2 ML/MIN AND IT IS A 5cm, 3,5MICRES,4.5mm, COLUMN.
THANK YOU VERY MUCH...
