Problem Provided is an electrolyte analyzer that allows reducing a load of a user in a replacement work compared with conventional one. Solution An electrolyte analyzer includes an ISE electrode 1 that includes at least one electrode, a reference electrode 2 that includes at least one electrode different from the ISE electrode 1, and a housing 200 that houses the electrodes of the ISE electrode 1 and the reference electrode 2. The housing 200 includes a pressing unit that presses the electrodes to one another, a first press switching unit 210 that switches the ISE electrode 1 between a secured state and a released state, and a second press switching unit 215 that switches the reference electrode 2 between a secured state and a released state. The ISE electrode 1 and the reference electrode 2 are each switched between the secured state and the released state.

A method of depositing of a film on a substrate with controlled adhesion. The method comprises depositing the film including metal, wherein the metal is deposited on the substrate using physical vapor deposition at a pressure that achieves a pre-determined adhesion of the film to the substrate. The pre-determined adhesion allows processing of the film into a device while the film is adhered to the substrate but also allows removal of the device from the substrate.
