Time-resolved Fluorescent TRF Filters
PRODUCT CATEGORIES
INOUIRY
Time resolved fluorescence (TRF) utilizes the ultra long fluorescence lifetime (μ s~ms level) of rare earth chelates (lanthanide elements) to detect after a delay in pulse excitation, completely filtering out nanosecond level spontaneous fluorescence backgrounds such as sample matrix and ordinary fluorescent dyes. The signal-to-noise ratio is much higher than steady-state fluorescence.
Standard filter configuration scheme
