Detector-Switching Analysis Using a Capillary Switching Device

Introduction

A capillary switching device allows switching of flo w lines with high accur acy. This device can be used to switch between 2 detectors , allowing concurrent analyses with m ultiple detectors to be conducted easily. Detector-switching analysis is diff erent from detector-splitting analysis, so when analysis is conducted using detector switching, the entire sample is flowing into the appropr iate detector, and accur ate information can be obtained from m ultiple detectors during a single analysis r un without sacr ificing sensitivity. (With the detector splitting technique, only a specific fraction of the sample is directed to each of the detectors during the entire analysis.) A switching program can easily be created with special software that can be do wnloaded from the Shimadzu website free of charge.
