Front Panel
Filament is common consumable for a MS system. Do you want to visually observe status of it? Is it lit? Has it been damaged and replacement required? When you install a column, do you want to clearly see accessible location in the column after it passes through the transmission line? The transparent observation window on the front panel could help you achieve all of this, while the indicating lamp will show you real running state of the MASS system.
