MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202611009503 A) filed by Gaurav Saxena; Deepika Sahu; Chitrakant Sahu; and Amit Joshi, Jaipur, Rajasthan, on Jan. 30, for 'autonomous spectrophotometric system for on-site nitrate analysis in water.'
Inventor(s) include Gaurav Saxena; Deepika Sahu; Chitrakant Sahu; and Amit Joshi.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an autonomous spectrophotometric system for on-site nitrate analysis in water (1). The system comprises a 3D casing (2) housing a quartz cuvette casing (3) and a cuvette holder (4) adapted to receive a quartz cuvette (5) containing a water sample. A UVC-LED driver circuit (6) is coupled to a UVC-LED (7) positioned on the first side of the quartz cuvette casing (3) to emit ultraviolet radiation through the quartz cuvette (5). A photodiode (8) is positioned on the second side of the quartz cuvette casing (3) opposite the UVC-LED (7) to receive transmitted radiation and generate an analog electrical signal. The analog signal is amplified by a transimpedance amplifier (11) and converted into digital data by an analog-to-digital converter (12), which is processed by a microcontroller (13). The microcontroller (13) is operatively coupled to a GPS module (14) and a display screen (15) and includes a wireless communication interface for transmitting measurement data to a cloud server (21). The system further comprises a power source (9), a DC charging jack (16), a lithium-ion charger management board (20), and an SPDT switch (19) for power control and charging."
