CN0503: Multiple Parameter Optical Liquid Measurement Platform

Reconfigurable multiparameter optical Liquid Measurement Platform for colorimetry, turbidity and fluorometry:

• On-chip digital filters allows platform to operate at full performance regardless of lighting conditions
• Benchtop instrument performance for handheld and portable applications
• Up to four independent light paths can be measured simultaneously

The CN0503 is a reconfigurable multiparameter optical liquid measurement platform capable of performing colorimetry, turbidity, and fluorometry. The design minimizes complexity by using a highly integrated, multimodal sensor front end capable of simultaneously driving four LEDs, and synchronously measuring four pairs of photodiodes at a flexible sampling rate. Furthermore, the front end has on-chip digital filters and high ambient light rejection that allow the platform to operate with full performance regardless of environmental lighting conditions.

Key Features and Benefits

• Minimizes complexity by using multimodal sensor front end
• Benchtop instrument performance while being adaptable to portable and handheld applications
• The platform supports a wide range of LED sources from infrared to ultraviolet wavelengths, and the four independent light paths can be simultaneously measured

Applications

• Instrumentation: Chemical Analysis and Analytical Instruments
