How will SONAR improve my results?
SONAR provides quantitative MS/MS data at UPLC speeds from a data independent acquisition (DIA) method, even when compounds have perfect coelution and samples are complex. As a result data is cleaner and library searches are more reliable while producing reliable quantitation. Lipidomics experiments are a great example of where SONAR is beneficial. Lipid samples can produce broad overlapping LC peaks and some analytes have common fragment ions. In this situation it is challenging to confidently assign fragment ions to their precursor ions with traditional DIA methods. SONAR generates MS/MS data removing this uncertainty and reducing data interpretation times.
Similarly, depth of coverage in proteomics experiments can be limited by the ability to easily collect true MS/MS data by DIA. Additional selectivity offered by SONAR can increase the number of protein identifications as a direct consequence of better quality data that improves the reliability of library searching.
How Does SONAR Work?
There are three instrument parameters that are key to SONAR:
This diagram demonstrates how the quadrupole slides over the mass range of interest, transmitting ions in sequence. Precursor and fragment ion data is recorded generating MS/MS results that can be viewed and processed individually. The resulting cleaner data is easier to interpret and increases the reliability of library searches.
