An investigation was performed to detail the method development work and subsequent analysis of various samples for selected glycol ethers using multidimensional gas chromatography with mass spectrometric detection in a sample matrix. A set of five bulk samples and nine charcoal tube samples collected at a newspaper printing facility was submitted for a determination of glycol ethers during the course of an investigation. The material comprising the bulk samples contained chemicals used in the offset printing process and in cleaning the printing plates and contained glycol ethers, kerosene (8008206) and other organic compounds. The limit of detection was 5 to 7 micrograms/sample for each compound investigated. The authors conclude that this method is useful for the analysis of industrial hygiene samples containing low levels of difficult to separate components. This system can separate complex mixtures of analytes and may significantly reduce method development time.
