Some soft solid layers' properties change significantly on contact with liquid; however, it takes a few minutes to mount a sample under the current FDG nozzle, causing inaccuracy of measuremnt. The sideways FDG (SiDG) device was developed by employing a second linear slide as a conveyer to move the sample into the liquid environment, so the time between when the sample is first immersed to and when the first reliable measurement is made can be recorded and the initial swelling can be monitored.
