Symmetry hplc column
WebRemedy. Column is ”underpacked”. Do a column performance test. Repack using higher flow rate. Use prepacked columns. Sample is not binding to column due to incorrect start buffer conditions. Adjust pH. Check salt concentration in start buffer. Sample too viscous. WebIn 1994, in an attempt to improve on the reproducibility of HPLC columns, Waters Corporation developed a process for the manufacture of packing materials using high purity raw materials as well as improved column packing procedures. This technology was first used in Waters’ Symmetry HPLC columns launched that year.

WebMay 8, 2001 · The binary gradient system with a linear gradient profile, employed in a method developed using a Symmetry C 18 column, gave excellent peak symmetry, resolution and reproducibility. Detection was performed at 220 nm which presented better absorptivity for these indole alkaloids giving a minimum detection limit of 0.5 µg. WebDec 1, 2024 · The column efficiency was acceptable (for a 5-cm, 2.7-µm column, ~8000–9000 plates). The USP tailing factor was 0.93 (Figure 5a), which can indicate a relatively symmetric peak shape with a net fronting; however, a visual examination showed that there is coupled fronting and tailing, which had to be eliminated experimentally by …
