Abstract
The present invention provides a downhole sample tank and a plurality of micro sample chambers. The micro sample chambers can have at least one window for introduction of visible, near-infrared (NIR), mid-infrared (MIR) and other electromagnetic energy into the tank for samples collected in the micro sample chamber downhole from an earth boring or well bore. The window is made of sapphire or another material capable of allowing electromagnetic energy to pass through the window. The entire micro sample chamber can be made of sapphire or another material capable of allowing electromagnetic energy to pass another material enabling visual inspection or analysis of the sample inside the micro sample chamber. The micro sample chamber enables immediate testing of the sample on location at the surface to determine the quality of the sample in the main sample tank or to enable comprehensive testing of the sample.
