2.2. Description of the mechanical elements
2.2.1. Operating arm
This mechanism positions the dis pen sing needle appropriately during the prepara tion of the analyses. An encoder
checks the vertical movement of the needle and a spring automatically stops it from falling in the case of a power cut.
The dispen sing pipe and the electrical hoses of the arm pass through the front casing
(1) X GUIDE
(2) X CARRIAGE
(3) Y CARRIAGE
(4) Y GUIDE
(5) NEEDLE UNIT
(6) CONTROL AND DISPENSING PIPE HOSE
The needle unit (5) supports the thermostated needle and can move on the Y carriage (3), which can move on the
Y axes (4). The Y axes are supported by the X carriage, which moves on the X axes (1). In this way, the needle can
be moved in the three Cartesian directions of X, Y and Z. The hose (6) houses the Teon dispensing tube and all the
electrical ho se s of the arm.
