A column with a high number of theoretical plates will have a narrower peak at a given retention time than a column with … WebCalculate post-column pressure as total pressure minus pre-column pressure. If post-column pressure is higher than 3.5 bar, take steps to reduce it (shorten tubing, clear clogged tubing, or change flow restrictors), and perform steps 1–4 again until the post-column pressure is below 3.5 bar. Note post-column pressure when it has
