High Sensitivity, High Stability and High Speed

 

  • High-sensitivity measurements can be performed with S/N ratios of 1,000:1 (RMS) or 350:1 (P-P).
  • Improved lower limit of quantitation. Measures concentrations up to 1 x 10-13 mol/L (fluorescein).

 

A redesigned optical system and signal processing system achieve the highest S/N ratio levels in its class. Even extremely dilute samples can be measured accurately.

 

The RF-6000 can measure fl­uorescence spectra from ­uorescein concentrations as low as 1 x 10-13 mol/L. Furthermore, due to an auto-gain control function that ensures measurements are performed using optimal measurement parameters, the system can perform accurate and highly quantitative measurements over a wide six-order dynamic range, from 10-13 to 10-7 mol/L.


 

Enables ultrafast scanning at speeds up to 60,000 nm/min. All wavelength regions can be measured in only one second. 3D fluorescence spectra can also be measured quickly.
 

The Xenon lamp offers long service life and high stability. The 2000-hour service life significantly reduces running costs. In addition, auto alignment technology allows customers to easily replace the lamp without tedious adjustment routines.  

 

 

A low-noise photomultiplier is included standard. It offers high measurement sensitivity for long wavelengths up to 900 nm. Consequently, it can measure substances that exhibit fl­uorescence at longer wavelengths, such as chlorophyll and indocyanin green (ICG). Below are Excitation and Emission spectra of indocyanin green, which is used for testing hepatic function and hepatic spare ability. The fluorescence peak was at 810 nm.
