The Bruker D4 Endeavor is built on the same platform as the D8 Series 1 and 2 instruments, but is designed for maximum throughput. They served users with high sample volumes who needed large autosamplers. These have been the ideal choice for industries like cement, geology, and aluminum production. The D4 comes standard with a 66-position autosampler including a 2-position transfer mechanism which allows for samples to be added or removed from the magazine without interrupting the measurement in-process.
