Stabilnost kromatografskega sistema preverimo tako, da večkrat vbrizgamo 4,0 µg/ml raztopine za umeritev (3.10.3), dokler niso dose žene konstantne višine (ali površine) vrhov in retenzijskih časov.
Check the stability of the chromatographic system, injecting the calibration solution (3.10.3) containing 4,0 µg/ml several times, until constant peak heights (or areas) and retention times are achieved.
