Description

Hadamard transform can improve the SNR by increasing the ion duty cycle in IMS. In this paper, the ion spectral signals were processed by Hadamard transform based on the IMS detector hardware platform. The results showed that Hadamard transform can greatly improve the SNR of the IMS detector in contrast with traditional method. (authors)
