The flow cells can also be used with PendoTECH’s Flow Cell Stand with integral couplers in place of the optical couplers to connect the fiber optic cables. The flow cell stand is optional for UV absorbance applications, but it is highly recommended for turbidity applications because it blocks out ambient light that would otherwise affect the readings. - Page 7 PendoTECH UV-VIS-NIR Photometer for UV Absorbance and Turbidity Measurements User’s Manual Revision 3 3. Optical Couplers/Flow Cell Holders (Varies per flow cell used and configuration type) Optional Flow Cell Stand 4. Example Flow Cells: Single Use Flow Cell, 1cm path length...

- Page 13 The LED is located internal to the photometer and is specific to the application. Therefore, the UV-VIS-NIR photometer is a dedicated instrument for monitoring only one or two specific analytes of interest.
- Page 14 Watch-Out: If the light source FWHM width is wider than the molecule’s absorption peak, that will produce false, low absorption values. Figure 1 LED wavelength spectrum example for 260nm UV-VIS-NIR photometer. Figure 2 LED wavelength spectrum example for 280nm UV-VIS-NIR photometer.
- Page 15 Absorbance and Turbidity Measurements User’s Manual Revision 3 Figure 3 LED wavelength spectrum example for 880nm UV-VIS-NIR photometer. In brief, the photometer works as follows: The measuring system is in the detector block of the photometer. Light is provided by an LED, which produces a stable light output at a narrow wavelength range.
