Algorithms and Databases: Unlocking Non-Targeted Screening of Small Molecules with Ambient Ionization Mass Spectrometry

September 1st 2022

Non-targeted analysis of small molecules with ambient ionization mass spectrometry (AI-MS) is enabled by new mass spectral libraries and algorithms, such as the inverted library search algorithm (ILSA) developed at NIST.

Figure 1: Seven prioritization strategies in non-target screening (NTS) by chromatography–HRMS, grouped by domain: chemical information (P1–P3), toxicological information (P5–P6), external information (P4), and preprocessing (P2, P7). Each strategy narrows the candidate space based on specific criteria. Combined, they reduce complexity and focus identification on environmentally relevant features.
