Manage Buffer Information:

Using this window, you can manage buffer information on your local system or in the current database. Normally, you must be identified as the investigator to view, delete, or update a buffer description in the database.

Dialog Items:

• Select Investigator This button brings up a window that allows selecting the current investigator for limiting buffer descriptions. Most users will only be able to view their own ior shared buffers. The Search item also limits the display of buffer descriptions.
• Database Check to select read or write of the buffer definitions to or from the database.
• Local Disk Check to select read or write of the buffer definition to or from the hard disk.
• Query Descriptions This button initiates a read of buffer definitions and populates the buffer list.
• Save Buffer Saves the current buffer definition to the hard disk or database.
• Update Buffer Updates the current buffer definition in the database or on the hard disk.
• Delete Buffer Deletes the current buffer from the database or hard disk.
• Density Density value set by buffer choice. It is also editable here.
• Viscosity Viscosity value set by buffer choice. It is also editable here.
• pH pH value set by buffer choice. It is also editable here.
• Compressibility Compressibility value set by buffer choice. It is also editable here.
• Optics Type of optics for spectrum management: Absorbance, Interference, or Flourescence.
• Manage Spectrum This button brings up a Manage Spectrum dialog to set Wavelength and Extinction pairs for the selected optics type.
• Buffer Description Description set by buffer choice. It is editable and especially useful when defining a new buffer. Select the shared checkbox to make the buffer globally visible.

• Synch components with DB Not normally needed, this button downloads teh current list of buffer components from the database to a file on the local hard disk.
• Reset Reset all buffer values to default setting.
• Help Show this documentation.
• Close Close the dialog. If this dialog is invoked from another process, this buttion will be marked Cancel.
• Accept This button will appear if the dialog is invoked from another process. It will close the dialog and provide the current buffer data to the invoking process.

To add or change a component to the current buffer, select the component in the lower left list and input the numeric concentration using the units indicated.
