User Accounts

Administration of user accounts, access rights and passwords. When the System - User Accounts… command or icon is invoked, the User Accounts dialog will appear. Such dialog is used to define all users working with the station and to set their access rights. User accounts settings are saved in the clarity.psw file.

User Accounts


Setting access rights is used predominantly to prevent intervention by untrained persons. This is not conceived as data protection against theft - such protection would require setting access rights in MS Windows. If any file is modified outside the Clarity station environment, it would be identifiable due to built-in security features.

User List

Provides a complete list of previously defined users. The name of the user to whom the content of all displayed fields relates will be displayed in inverse mode (i.e. white text on the blue background). Other users are selected by using arrow keys or clicking your mouse on the desired user name.


Adds a new user. During this operation, the new User name is checked against existing user names for possible collision.


Duplicates a selected user account from the user list. Rights from section "Other Users Can", "Access To" and "User Access Rights" are copied from the original user.


Erases a selected user from the user list. If all users are deleted the station automatically switches to “all users” mode. In such mode the password is no longer required.

Password Restrictions


Password Restrictions parameters are common to all users.

Min. Length

Refers to the minimum length of the password entered. A password shorter than the prescribed number of characters will not be accepted.

Life Time

Refers to the period of a password's validity. After its expiration the user must select a new password.

Expiration Warning

Alerts the user specified number of days prior to a password’s expiration.

Password Reuse

Relates to the period from which an already used password can be used again.

Auto Lock

If the user doesn't have any activity in Windows, all opened Instruments will be locked after specified time in minutes. All windows opened on instruments will be hidden and the user has to unlock the Instrument by clicking on its picture in the Clarity window.


When an Instrument is Auto Locked, all eventual unsaved changes in modal dialogs (Method Setup, Single Analysis, Report Setup, etc) are discarded and those dialogs are closed.

User Details for:

The fields displayed in the lower part of the window always relate to the user whose user name is selected from the User List. Only a user with adequate access rights can change the settings of those access rights (i.e. such user has selected Open User Accounts in the User Access Rightssection).


User Name

User name will automatically be placed in all headers of files that are created while working in the station. The user name will be displayed along with the Created by or Analyst phrase when a file is selected. It is compulsory for a user to fill in this field and forbidden for two users to have the same user name.

Desktop File

Refers to the name of the file (*.dsk) in which the desktop settings are saved. The file contains settings regarding size, location and visibility of the Instrument windows as well as all the amendable Instrument parameters which are not part of system files. If this field is left empty, it will be filled in automatically according to the User Name field.

This setting is common to all Instruments available for the user.


If you wish to share the same settings for several users, you can link them to the same desktop file. To do so, simply fill in the name of the user with desired settings.


Provides a user’s detailed description.


User Name and Description are part of signature during electronic signing.

Other Users Can

This section serves for setting what other users can do with files created by selected user.

Read & Write

Other Clarity users can view and edit files created by selected Clarity user.


Other Clarity users can view files created by selected Clarity user but cannot edit or otherwise modify them.

No Access

Other Clarity users does not have any access to files (even for reading them) created by selected Clarity user.

For example three Clarity users exist - Alice, Bob and Cameron. Alice's account is set to No Access option, Bob's account is set to Read option and Cameron's account is set to Read & Write option. Alice and Cameron will be able to open files (chromatograms, methods, calibrations...) created by Bob but will not be able to modify them. Alice and Bob will be able to open and modify files created by Cameron (because of his Read & Write option). Bob and Cameron will not be able to read nor modify files created by Alice (because of her No Access option).

Access To

Instrument X

Defines which Instruments the user may access within a station.

User Access Rights

Open User Accounts

A user with access to user accounts can add, delete or change the access rights of other users. A selected checkbox is essentially equivalent to allocating administrator rights. It also allows the user to use the System - GLP Options… command to change the rules for files overwrite. User without such rights can't even open the User Accounts dialog.

Open Configuration

Checking this field allows specific user to access following dialogs: Configuration, Units Setup, Directories and Digital Outputs.

Edit Method

Enables the user to create, delete or edit a method. A user with no rights to edit method still can Send Method to Instrument.


If the method is changed by any reason (the MODIFIED inscription is shown in the Instrument window header) and the user without the Edit Method privilege should leave the Instrument window, all changes to the method are automatically discarded.

Edit Chromatogram

Enables the user to edit chromatograms.

Edit Calibration

Enables the user to create and edit calibrations.


Enables the user to switch among all available projects directly from the Instrument window without need to perform log-off and log-in steps. When enabled the respective user will have access to Project Setup Dialog from Instrument window. When disabled the user will still posses an option to switch to any different project via Login Dialog. This item does not control privilege for creation of new project or assignment of project to respective Clarity users at all.


It is not possible to prevent any Clarity user from creating new project via Login Dialog and Project Setup Dialog.

Import Chromatogram

Enables the user to import chromatograms.

Take Control of Locked Instrument

Enables the user to take control of instrument from another user. The instrument has to be locked by the previous user using Auto Lock or by using Instrument - Lock Instrument X command in Main or Instrument window. All actions will be logged into Audit Trails under the newly logged user. If the new user does not have Start Acquisitionrights, running analysis or sequence will be finished but next analysis will not be started.


All eventual unsaved changes in files not saved by the previous user will be discarded.


It is recommended to set one common Desktop File for all users with this option enabled. Otherwise desktop of the first logged user will be used for all users that take control over the Instrument, until the Instrument is closed again.


It is also recommended to set the same Edit... rights for users that plan to take over Instruments as different rights may limit the options of second user.


It is possible to take control of locked Instrument using the Command line parameters. Always include the user (user=…) and password (p=…) parameters for each command, because the instrument is kept locked.

Edit Sequence

Enables the user to create and edit sequences.
