Solutions for Improving Data Processing Efficiency
for PFAS Analysis
Because of how PFAS are defined, they include an extremely wide range of compounds. Therefore, the number of compounds covered by various official analytical methods will presumably increase in the future.
One issue with the increasing number of target compounds is processing so many peaks in chromatograms. Having to process so many peaks places a large burden on operators, and the peak integration process itself strongly reflects the subjectivity of the analysis operator.
To achieve high analytical throughput and improve the reliability of results, a highly accurate peak integration program is essential.
Using Peakintelligence for Efficient Data Analysis
—Applications for PFAS Analysis—
To address the various issues involved in chromatogram peak integration, Shimadzu offers Peakintelligence, chromatogram peak integration software that features an algorithm developed using AI (artificial intelligence), as a solution. Parameterless automatic peak integration can eliminate the subjectivity of the operator doing the analysis while also increasing accuracy and reducing the number of incorrectly detected peaks.
Using this algorithm to process PFAS analytical data resulted in extremely high accuracy and fewer incorrectly detected peaks. PFAS analysis, in particular, can sometimes involve trace quantities that require processing peaks with small S/N ratios, but the algorithm can integrate peaks for even such compounds without any problems. The high accuracy of peak integration also reduces the time spent on making corrections, which can be expected to result in significant labor savings.

Peakintelligence™
Until now, peak-finding algorithms have required the user to fiddle with multiple parameter settings before they can start data processing. Also, when the algorithm can't deal with a chromatogram, an experienced user has to select the peak by hand. This all adds up to extra time and hassle.
