Overall Overview

A mass spectrometer is a precision scientific instrument that performs qualitative and quantitative analysis of substances by measuring the mass-to-charge ratio (m/z) of ions. It ionizes sample molecules, separates ions of different masses, and detects them, so as to determine the composition, structure and content of substances. Widely applied in chemical testing, biomedicine, environmental monitoring, food safety, material analysis and other fields, it serves as the core equipment in modern analytical science.

The analog signal input enters Acela Micro’s self-developed ADC after conditioning. The data after analog-to-digital conversion is transmitted to the FPGA. External trigger signals can be fed into the FPGA through a high-precision trigger conditioning circuit. Meanwhile, the board can also act as a trigger source to generate and output trigger signals to other modules. The FPGA collects analog signals based on trigger signals, and transmits the digitally processed data to the system host via PCIe.

Advantages & Value

The mass spectrometer solution developed by Xunxin Microelectronics adopts domestically self-developed ADC chips as the core data conversion devices of the acquisition card. It supports sampling rates from 1 GSps to 20 GSps, and features high-precision external triggering and frame accumulation functions. The solution allows customers to conduct secondary development on FPGA. This series of products has been mass-applied in high-end time-of-flight mass spectrometers, helping domestic high-end time-of-flight mass spectrometry equipment reach the internationally advanced level.
