The RF-10AXL, Shimadzu's newest fluorescence detector for HPLC, offers a refined optical design for the ultimate in high sensitivity detection. This unit offers an improved Raman signal-to-noise ratio of 300 for excellent sensitivity, improved wavelength accuracy of ± 2.0 nm for strong between-unit consistency. A newly developed ratio system compensates for lamp intensity fluctuation and provides superb noise characteristics. The RF-10AXL features other enhancements including a new remote lamp on/off function to allow lamp shutdown upon run completion, and a new rugged flow cell design with elevated back-pressure tolerance and backward compatibility with the RF-10AXL.
