1Measurement precision
If the user manually determines waveform processing parameter values, then the peak separation can be adjusted, but it is difficult to determine appropriate values and the process is time-consuming
Solution Approach 1:
The system automatically performs preliminary waveform processing using multiple different parameter values before user selection, generating multiple peak separation results in advance. This allows the user to review and select from pre-computed options rather than manually determining parameters from scratch, significantly reducing the time required while maintaining accurate peak separation.
Solution Approach 2:
The system creates multiple copies of the waveform processing results, each corresponding to a different parameter value. The user can review these copied results and select the most appropriate one, eliminating the need for repeated manual processing and parameter adjustment, thus saving time while ensuring accurate peak separation.
2Reliability
If a single waveform processing parameter value is used, then the processing is simple, but the results vary when the same sample is analyzed multiple times due to device accuracy and column deterioration
Solution Approach 1:
The system evaluates multiple waveform processing parameter values simultaneously and displays their respective results. This allows the user to select a parameter value that provides consistent and reliable peak separation results across multiple analyses, even when device accuracy or column performance varies. The increased parameter evaluation capability ensures reliable quantitative analysis despite the more complex selection process.
