Analytical method for the determination of triglycidyl isocyanurate (TGIC)

Translation of DGUV Information 213-566 (former BGI 505-66 or ZH1/120.66)

CAS Number: 2451-62-9

Synonyms: 

  • TGIC
  • Triglycidylisocyanurat
  • Tris(2,3-epoxypropyl) isocyanurate

Method 01 – HPLC – limited suitability: category E1

Sampling with a pump and collection on a glass-fibre filter, high-performance liquid chromatography (HPLC) after elution.

This method permits the determination of triglycidyl isocyanurate concentrations in working areas averaged over the sampling time after personal or stationary sampling.

Principle

A pump is used to draw a measured volume of air through a glass fibre filter, taking into account the definition of inhalable dust fraction. The TGIC is extracted from the collected dust by treatment with tetrahydrofuran. The matrix is precipitated by adding water. The sample is then dissolved in a phosphoric acid buffer/acetonitrile mixture, filtered and analysed by liquid chromatography.

Limit of quantification (LOQ)

Absolute: 0.03 µg TGIC, equivalent to 2.5 µg per sample.

Relative: 0.008 mg/m³ for a 420-litre air sample, 2 mL sample solution and 25 µL injection volume.

The measuring method is of limited suitability (E1).

The complete measuring method is available in Volume 9 of the series „Air Monitoring Methods″, 2005, published by the DFG.
