Segmented Detector Array for Targeted Mass Spectrometry

The detector array is segmented into active detector elements and inactive dummy elements. Only the active elements are connected to readout circuits, while dummy elements are simple conductive structures without expensive electronics. This segmentation allows the physical detector region to be extended without proportionally increasing the number of expensive readout circuits, thereby reducing the cost per unit length while maintaining the necessary detector element width for high mass resolution.

The dummy elements serve multiple functions: they maintain the physical continuity and geometric structure of the detector array, provide electrical grounding and field uniformity, and enable the use of simpler, less expensive readout circuitry compared to fully active detector elements. This multi-functionality allows the system to achieve high mass resolution without the prohibitive cost of having every detector element fully active with its own readout circuit.

The detector array is segmented into active detector elements connected to readout circuits and inactive dummy elements that are not connected to expensive readout electronics. This segmentation enables the system to maintain versatility by having sufficient active elements to detect various m/z values while dramatically reducing the overall cost and complexity by replacing many potential active elements with simpler dummy elements.

Instead of implementing a full array of expensive active detector elements with readout circuits across the entire detection region, the system uses partial action by deploying only the minimum necessary active detector elements to achieve the required detection capability, with the remainder being simpler dummy elements. This partial implementation achieves the necessary versatility at a fraction of the cost of a complete active array.
