ing acquisition runs and deletes
the file from the list of pending
MVS files. Finalizing a MVS
sequence will also lock the valida-
tion and prevent it from further
modification.
MVS sequences are created with a
specific command (Create Study
and MVS for ChemStation Plus)
in the Method Validation Pack
software. They are automatically
built according to the validation
configuration in the Method
Validation Pack software - no user
interaction is required. The MVS
template is stored as a text docu-
ment with the validation in the
Document Management System
(DMS) of the Method Validation
Pack software. Each injection
translates into one line in the
sequence table; repetitive injec-
tions of the same sample receive
only one sequence line but write
the number of injections in the
related sequence column. The
MVS files automatically include
information on the sample type,
number of injections, sample
name, and they fill in the method
validation name for the analytical
method. They also carry addition-
al information in protected cus-
tom fields. This information dis-
plays the checkpoint name, the
component name and a unique
run-ID for easy identification in
the sample information text dia-
log. These fields can only be con-
figured and edited through
Method Validation Pack software.

data management.
Interaction with ChemStation
for data acquisition
If Method Validation Pack is
installed in a ChemStation Plus
data system ChemStation will
offer additional functionality to
run and execute method valida-
tion sequences. It will receive an
additional Method Validation
menu item in the ChemStore
menu (figure 36), as well as two
new buttons in the graphical user
interface. The first button switch-
es ChemStation into method vali-
dation mode and back to the stan-
dard mode. The second button
opens the sequence import dialog.
If method validation mode is
enabled, the user has access to the
method validation sequence
import menu. The import window
displays a list of pending method
validation sequences (MVS files)
including status information and
user assignment of the MVS files.
Users now select the MVS files
they want to download from the
list of pending files. An MVS file
has an assignment to one specific
user or it has no user assignment
and is thereby an all-user job for
all users with a valid logon. As
soon as a user has loaded a pend-
ing validation sequence for execu-
tion in the ChemStation, it is
blocked for other users. Partial
MVS sequences can be set to
