Z Motor Arm in contact with sediment core

GeoTek MSCL-XZ Z motor arm with XRF, visible and near-infrared spectrophotometer, and magnetic susceptibility point sensor in contact with a sediment core surface to take discrete measurements. The LabSpec Near-IR ASD is visible on the left side of the Z motor arm. The white magnetic susceptibility point sensor is in the center of the photo in contact with the sediment core surface.
