BUCHI KjelSampler K-377 - Manual (Page 85)

6 Operation
85 K-375/376/377 Operation Manual, Version B
To change the order of steps within a sequence
you have to delete selected steps and to add them
again in a reasonable order.
NOTE
Except the steps “Rack 4“, “Rack 12“, and “Rack
20“ none of the steps can be changed from within
the sequence. (See the table at the beginning of
this chapter for details.)
The tasks Preheating, Priming, and Cleaning are
always performed “via sampler”, if used within a
sequence. Even if those tasks are set to “unit only”
within the “System Preparation” under “Preparative
tasks”, this setting will be omitted.
Click on the Rack step to adapt the settings of the
rack and to add samples to the rack.
Press SETTINGS and adapt the settings for the
rack:
“Determine blanks first” Yes/No
(If blanks are determined first, the risk of a cross-
contamination can be minimized for the blanks.)
“Pause after blank calculation” Yes/No
A pause after the blank calculation leaves a user
with operator rights the chance to eliminate a faulty
blank determination from the calculation before
any sample determinations are corrected with the
calculated blank.
The third setting is only available for 2-tray samplers:
“Use tray in sampler” A/B
Define the position of the rack in the K-377 sampler.
The step will be marked with A or B.
