1Productivity
If high-concentration reagents are used to reduce replacement frequency, then productivity is improved, but measurement precision deteriorates due to concentration variability affecting analytical values
Solution Approach 1:
The reagent system is segmented into multiple concentration levels (high-concentration stored reagent and diluted working reagent). The high-concentration reagent is stored in the bottle to extend usage duration, while automatic dilution generates working reagents at precise concentrations for accurate measurements, resolving the conflict between productivity and measurement precision.
Solution Approach 2:
The system performs preliminary dilution of high-concentration reagents before they are used for measurements. By pre-diluting the reagent to the exact working concentration using an automatic dilution device, the system ensures measurement precision is maintained while allowing the use of high-concentration stock solutions for extended periods, thereby improving productivity.
2Measurement precision
If reagent bottles are replaced frequently to maintain concentration accuracy, then measurement precision is improved, but loss of time increases due to replacement and recalibration operations
Solution Approach 1:
The system performs preliminary dilution of high-concentration reagents before they are used for measurements. By pre-diluting the reagent to the exact working concentration using an automatic dilution device, the system ensures measurement precision is maintained while allowing the use of high-concentration stock solutions for extended periods, thereby improving productivity.
Solution Approach 2:
The automatic dilution device enables the reagent system to self-regulate its concentration. The device automatically monitors reagent concentration and performs dilution as needed, eliminating the need for manual bottle replacement and recalibration by operators, thus reducing downtime while maintaining precision.
3Measurement precision
If automatic dilution devices are added to improve reagent concentration accuracy, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The automatic dilution device is designed to be multi-functional, serving both as a dilution device and as part of the reagent supply system. By integrating the dilution function into the existing reagent management infrastructure, the system achieves improved measurement precision without proportionally increasing overall device complexity.
Solution Approach 2:
The automatic dilution device enables the reagent system to self-regulate its concentration. The device automatically monitors reagent concentration and performs dilution as needed, eliminating the need for manual bottle replacement and recalibration by operators, thus reducing downtime while maintaining precision.
