Just Accepted “Just Accepted” manuscripts have been peer-reviewed and accepted for publication. They are posted online prior to technical editing, formatting for publication and author proofing. The American Chemical Society provides “Just Accepted” as a free service to the research community to expedite the dissemination of scientific material as soon as possible after acceptance. “Just Accepted” manuscripts appear in full in PDF format accompanied by an HTML abstract. “Just Accepted” manuscripts have been fully peer reviewed, but should not be considered the official version of record. They are accessible to all readers and citable by the Digital Object Identifier (DOI®). “Just Accepted” is an optional service offered to authors. Therefore, the “Just Accepted” Web site may not include all articles that will be published in the journal. After a manuscript is technically edited and formatted, it will be removed from the “Just Accepted” Web site and published as an ASAP article. Note that technical editing may introduce minor changes to the manuscript text and/or graphics which could affect content, and all legal disclaimers and ethical guidelines that apply to the journal pertain.

ABSTRACT

28

Recently, a generally applicable screening method for multiresidue pesticide analysis, which

29

is simple, quick, accurate, and has a reliable performance, is becoming increasingly important

30

for food safety and international trade. Here, we have proposed a high-throughput screening

31

methodology that enables the detection of multiresidue pesticides using supercritical fluid

32

chromatography coupled to a high-performance benchtop quadrupole Orbitrap mass

33

spectrometry (SFC/Q Exactive) and an automated library-based detection. A total of 444

34

chemicals covering a wide polarity range (logPow from ‒4.2 to 7.7) and a wide molecular

35

weight range (from 99.0 to 872.5) were analyzed simultaneously through a combination of

36

high mass resolution (a value of m/∆m = 70,000), high mass accuracy (
