What You'll Learn

  • PEG Without the Headaches

    How BrightSpec-MRR™ eliminates the dilution, filtration, and derivatization steps that slow down GC/MS workflows.

  • High Confidence

    How BrightSpec-MRR™ achieves LOQs that meet USP acceptance thresholds for ethylene oxide and acetaldehyde.

  • Fast, Parallel Analysis

    How headspace-MRR delivers results in under a minute per analyte with up to 8 samples running simultaneously.

Problem and Solution

Problem

PEG-3350 is essential across pharma and consumer products, but its viscosity makes impurity testing slow and error-prone. Traditional GC/MS requires dilution, filtration, and complex method development, all while regulators push for stricter testing.

Solution

BrightSpec-MRR™ delivers direct, chromatography-free analysis of ethylene oxide and acetaldehyde. With headspace sampling, results are clear, fast (40–60 seconds), and meet USP thresholds—offering confidence and efficiency in a single platform.
