  1. Airborne environmental endotoxin : a cross-validation of sampling and analysis techniques.

    Article - En anglais

    A standard method for measurement of airborne environmental endotoxin was developed and field tested in a fiberglass insulation-manufacturing facility.

    This method involved sampling with a capillary-pore membrane filter, extraction in buffer using a sonication bath, and analysis by the kinetic Limulus assay with resistant-parallel-line estimation (KLARE).

    Cross-validation of the extraction and assay method was performed by comparison with methanolysis of samples followed by 3-hydroxy fatty acid (3-OHFA) analysis by gas chromatography-mass spectrometry.

    Direct methanolysis of filter samples and methanolysis of buffer extracts of the filters yielded similar 3-OHFA content (P=0.72); the average difference was 2.1%.
