• Description:
  Thank you for giving us the opportunity to respond to the comments of Warren D. Hendricks and Gerald R. Schultz on our article "Determination of 1.3-Butadiene Down to Sub-part-per-million Levels in Air by Collection on Charcoal and High-Resolution Gas Chromatography" [App. Occup. Environ. Hyg. 5(5):310:1990]. In stating that OSHA Method 56 specifies analysis by packed column chromatography, we only meant that the method explicitly details use of a packed column. For both NIOSH and OSHA methods, use of the "specified" column is not mandatory. There is, however, a feature of the OSHA Method 56 that may inhibit the use of a capillary column to achieve better resolution of interferences. A 10 percent coating of the absorbent with 4-tert-butylcatechol (TBC) results in approximately 9 ug/ul of TBC in desorbed samples. In example chromatograms for the packed column, TBC does not appear to elute, though two small "artifactual" peaks are said to be produced from TBC. An accumulation of TBC may not be tolerable with capillary columns. [Description provided by NIOSH]
