Two problems have a tendency to shorten the life time of an analytical column. Initially, solutes that bind irreversibly into the stationary phase degrade the column’s performance by lowering the level of stationary section readily available for effecting a separation. Next, particulate content injected Along with the sample may perhaps clog the
