- Description
- Question Received : I will need to know the exact requirements for excitation and emission for both sets of filters. Example: Excitation + Emission #1 need to be EX 340+/- 30nm + EM 450 +/-25nm Excitation + Emission #2 need to be EX 300-370nm + EM 400-475nm Your RFQ lists only approximate ranges for both filter sets. Can you provide clarification? Reply: An instrument that meets the EPA's minimum requirements shall have filter combinations to measure fluorescence at 2 different portions of a CDOM Excitation Emission Matrix. This means there should be no overlap of emission wavelengths, including filter bandpasses. An example : emission filter 1 = 420 nm +/- 20 nm bandpass emission filter 2 = 470 nm +/- 20 nm bandpass The excitation filters shall be selected between Exc = 300-370 nm, where, either one or two different wavelengths could be chosen. Two combination examples could be: (1) Ex/Em 1 = 350 / 420 nm; Ex/Em 2 = 370 / 470 nm (2) Ex/Em 1 = 350 / 420 nm; Ex/Em 2 = 350 / 470 mn The choice of filters, in conjunction with lamp and detector design of a specific manufacturer should be based on optimizing CDOM fluorescence detection in natural waters.
