An analysis case using the CFA method for measuring nitrogen and phosphorus in seawater, etc.
Publication of case studies using the CFA method for the measurement of total nitrogen and total phosphorus in seawater and wastewater.
The nitrogen and phosphorus analysis using the auto-analyzer from Sanyo Techno Marine Co., Ltd. adopts the Continuous Flow Analysis (CFA) method, and we are currently using our "QuAAtro2-HR." When introducing flow analysis methods, the focus is generally on improving efficiency, but after implementation, there are unique challenges and innovations in equipment management from the users' perspective. This document reports on the insights gained by Sanyo Techno Marine Co., Ltd. as a user. [Contents] ■ Overview of the analytical equipment Analysis methods and specifications of the equipment in use ■ Comparison of this model with manual analysis Comparison of manual analysis and CFA from the perspectives of "effectiveness" and "burden" ■ Contamination prevention measures in NH4-N analysis Measures to prevent contamination using soundproof boxes, etc. ■ Measures to address carryover in total nitrogen analysis ■ Summary *For more details, please refer to the PDF document or feel free to contact us.

The auto-analyzer developed by the former Technicon Corporation, a global pioneer in continuous flow analysis devices, is still widely used in analytical laboratories around the world today. In Japan, it continues to operate as an essential device in national and public research institutes, testing laboratories, and corporate factories and testing facilities. Our company, BL Tech Co., Ltd., has inherited approximately 40 years of auto-analyzer business in Japan and is focusing on the development and manufacturing of optimal continuous flow analysis devices to meet the current hot demand.
