High Performance Liquid Chromatography (It has also been referred to as High Pressure LC) •HPLC has been around for about 35 years and is the largest separations technique used •The history of HPLC: •Beginning of the 60’s: start of HPLC as High Pressure Liquid Chromatography •End of the 70’s improvements of column material and
Mar 01, 2022 · The HPLC was equipped with a Quaternary Pump VL and a UV Diode Array Detector. The signal used for the UV absorption was 254 nm. 2 μl of the filtered solution was injected and eluted at a 1 mL/min rate using an acetonitrile gradient (5 – 60% during 3 min) and 10 mM of NH 4 HCO 3 + 30 mM of NH 3. Before the test, the solution was filtered

(A) HPLC chromatogram of the F-FAPI-74 reference standard from the ultraviolet (UV) detector, Rt of 9 min 45 s. (B) HPLC chromatogram of the [18 F]FAPI-74 from the radiodetector, Rt of 10 min and 2 s
Jul 29, 2020 · RP-HPLC separation was performed on Aijiren Quaternary LC coupled to a diode array detector (DAD). Best peak resolution was demonstrated using Aijiren AdvanceBio RP-mAb Diphenyl, 2.1 × 100 mm column, 0.5 mL/min flow rate, with a column temperature of 60 °C and a step wise gradient (3 min washing at 35% B followed by 35% B to 39%
On HPLC I found a reverse phase procedure in the literature that works quite well: 0.1 M triethyl ammonium acetate at 0.9 mL/min with 2% / min gradient of MeCN (SolvB = 0.1 M TEAA with 25% MeCN
A clogged column frit is another common HPLC problem. To minimize this problem from the start, use a precolumn filter and guard column. To clean the inlet, first disconnect and reverse the column. Connect it to the pump (but not to the detector), and pump solvent through at twice the standard flow rate.
