The manufacturer of the Shimadzu RF-10AXL Fluorescence Detector is Shimadzu. The Shimadzu RF-10AXL offers a refined optical design for the ultimate in high sensitivity detection. The RF-10AXL 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-10A. The RF-10AXL has a compact, modular design and is used with an SCL-10Avp system controller to complement any existing HPLC system. It easily integrates with other Shimadzu LC-10A Series components via fiber optic communication cables for "plug and-play" convenience in building a customized Shimadzu LC system. The pre-owned products will be thoroughly cleaned and fully tested to perform at manufacturer specifications before shipping.
