After changing column, concentration is lower of the QA, GC

My OA changed concentrations after changing the column, the settings were:

40 m, 530 um, 100 um but the column is now: 

30m, 530um, 0,88um. 

How can i make sure its the good amount of concentration again? split ratio is 2:0 and injection vol is 2 ul
