1. World's Highest Level of Sensitivity
By adopting a horizontal positioning system for the redox cell, the flow path from the cell to the detector has been reduced to one-third compared with previous SCD detectors. Unstable components can be introduced into the reactor chamber at a high speed, which minimizes sensitivity loss and enables analysis to be performed with the world's highest level of sensitivity. (The sensitivity is about three times higher than the SCD previously provided by Shimadzu.)
2. Dramatically Improved Operability and Maintainability
In models with built-in vertical redox cells, replacing the consumable parts (the inner pyro tube) is a difficult, time-consuming process. With the Nexis SCD-2030 horizontally positioned sulfur chemiluminescence detection system, replacement of the inner pyro tube takes only five minutes. In addition, the Nexis SCD-2030 automatically adjusts the gas and temperature, so measurement preparations are completed with just a single touch. Combined with the LabSolutions analysis data processing system, the entire workflow from system check to starting/ending analysis and stopping the instrument can be automated. Automating the processes performed by the operator supports a more efficient workflow, and can prevent damage and degradation of detectors due to human error.
3. High Stability
The Nexis SCD-2030 utilizes the first horizontal positioning system in the industry for the redox cell, a core component of sulfur chemiluminescence detectors. This design enables a stable redox reaction by ensuring sufficient reaction zone and reaction time. Compared with other companies' SCD detectors, the Nexis SCD-2030 achieves higher, long-term stability (24-hour sensitivity fluctuation is about 1.6 times better), while the effect of differences in analytical conditions, such as the column flowrate, is minimized.
