Mass Spectrometry Sampling With Quality-Threshold Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data acquisition techniques in mass spectrometry, such as Acoustic Mist Ionization, often waste time acquiring unnecessary data and require reanalysis due to insufficient data quality, particularly in High Throughput Screening applications, where efficient sample analysis is crucial.
Innovation Solution
Implementing a method that continuously releases analyte samples until a predetermined quality threshold, such as intensity or spectral quality, is met, allowing for optimized data acquisition and minimizing the need for reanalysis by moving on to the next sample once the threshold is exceeded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous data acquisition is performed on all samples, then complete data sets are obtained, but time is wasted acquiring unnecessary data and reanalysis is required due to insufficient quality
Solution Approach 1:
The system continuously monitors data quality metrics (such as signal intensity, signal-to-noise ratio, or spectral quality) during the acquisition process and uses this feedback to dynamically adjust the sampling strategy. When quality thresholds are met, the system automatically transitions to the next sample, preventing waste of time on sufficient data while ensuring inadequate data is detected and reanalyzed
Solution Approach 2:
The data acquisition process is made dynamic rather than static. The system adapts the number of scans or integration time for each sample based on real-time quality assessment. Samples with sufficient signal quality require fewer scans while samples with poor quality automatically trigger extended acquisition or reanalysis, optimizing the balance between data reliability and time efficiency
2Productivity
If Acoustic Mist Ionisation is used for high throughput screening, then sampling rate increases to up to three samples per second, but unnecessary data acquisition and reanalysis still occur
Solution Approach 1:
Even at high sampling rates of three samples per second, the system incorporates real-time quality feedback mechanisms that monitor each sample's data adequacy. This feedback loop enables the system to immediately identify samples requiring reanalysis versus those with sufficient quality, preventing the time waste associated with acquiring complete data sets on all samples when most may be sufficient
Solution Approach 2:
The system performs preliminary quality assessment during the initial acquisition phase rather than waiting until complete data collection. By evaluating data quality metrics early in the process, the system can determine whether additional scans are necessary before committing full acquisition time, thereby eliminating unnecessary reanalysis cycles while maintaining high throughput

Implementation Method 1
Acoustic Mist Ionisation (AMI) is a technique which is used to generate or liberate ions directly from liquid sample confined within, for example, the wells of a sample plate
Implementation Method 2
Mass spectrometry may be employed to determine the relative abundance of two or more ions

AI summary
A method of mass spectrometry is disclosed comprising repeatedly or continuously causing first analyte sample to be released or ejected from a first sample. A determination is made as to whether or not a quality threshold such as an intensity threshold has been met or exceeded, wherein if the quality threshold has been met or exceeded then the method further comprises repeatedly or continuously causing second analyte sample to be released or ejected from a second sample.
