Analytical Vials. Vials play a significant role in analytical analysis and result reproducibility. Vials must be inert and free of extractables or leachables to prevent affecting results. Using certified, application-specific, contaminant-free vials can significantly reduce risk. We offer a broad spectrum of Supelco ® products including

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.

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
Kinetic studies were conducted on three unrelated reaction types using traditional and modified reaction monitoring tools. The Aza-Piancatelli rearrangement was studied through ReactIR and HPLC-MS to obtain a better understanding of why the substrate scope was limited. It was found that the Lewis acid catalyzed reaction is often zero-order, dependent on the lanthanide metal used. Off-cycle
Jun 20, 2018 · Lyophilised whole cells of E. coli (30 mg) containing overexpressed ScFDC were rehydrated for 30 min at 30 °C with 120 rpm shaking in phosphate buffer (950 μL, 100 mM, pH 6.0) in 1.5 mL plastic Eppendorf tubes. Substrates were supplied by adding 50 μL of 200 mM stock solution in DMSO to achieve a substrate concentration of 10 mM in 1 mL of
