Column degradation Replace column. With high temperatures: Avoid high temp in combination with aggressive buffers (e.g., phosphate)—reduce to uncritical temperature (e.g., 40 °C), replace column type (e.g., hybrid column). With high pH: Use high pH compatible column type. Column void (particularly at UHPLC pressures) Replace column.

Table 1). For high quality analytical results, attention to the quality of solvents used in mobile phase preparation is essential. In particular, the amount of particulates, typically measured as residue after evaporation for organic solvents must be minimal. LC/MS grade solvents and volatile buffers with minimal residue are preferred.
