The AOC-20 provides the highest degree of reliability. This means that the unit produces reproducible results, with a minimum of problems such as bent needles, evaporating samples, etc. Maintaining reproducible results requires that periodic maintenance be performed, such as changing the injection port septa or syringe.
With the AOC-20, these procedures are simple and you can comfortably perform them without fear of adversely affecting instrument performance.
