A high throughput liquid chromotagraphy column assembly for separating a large sample with a selected mass weight and fluid volume. The resistive heater includes a metallic component that is electrically conductive and an oxide, nitride, carbide, andor boride derivative of the metallic component that is electrically insulating. A first flexible conductor extends parallel to and spaced apart from the elongated monopole radiating element of the whip antenna to form the parallel wire transmission line. The imaging lens assembly includes a variable liquid lens controlled by the controller for optically modifying the return light. A removable bin allows easy removal of the compacted trash.
