Analysis of Bleeding Matter on the Surface

Print

Summary

Troubles as listed below that occur with films and moldings are caused by any bleeding matter (additives and oil) on the surface of the materials in some cases. Identification of such bleeding matter will enable you to take corrective measures to cope with the troubles with films and moldings.

Physical properties: Inadequate heat-sealing strength, poor pealability
Appearance: Whitening, bloom, abnormal gloss,
Touch: Stickiness abnormal sliding

Flow of analysis

Pretreatment
Wiping of the surface

Qualitative analysis
Gas chromatograph/mass spectrometer (GC/MS)
Field desorption mass spectrometry (FD-MS)
Infrared spectroscopy (FT-IR)

Quantitative analysis
Gas chromatography (GC)
Derivatization/gas chromatography (GC)
Liquid chromatography (LC)

Example of qualitative analysis

Qualitative analysis of film bleeds by FD-MS

Bleeding matter was qualitatively analyzed from the molecular ions (molecular weight) intensely detected.

Based on our many years of experience in polymer analysis, we can propose various analytical methods. We have approximately 450 types of standard products of additives.
