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 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.
