Retention Indices

The thermal degradation of industrially manufactured polymers based on polyethylene, polypropylene and polystyrene was studied. The pyrolysis was carried out in a tubular quartz pyrolyzer at 510°C and the products were separated on capillary columns coated with squalane and OV-17 and were identified on the basis of their retention indices.

Abstract Capillary gas chromatography with nitrogen-specific detection allows rapid screening of numerous drugs of toxicological interest. However, for accurate identification of individual peaks, the system must be well calibrated, e.g., through the use of retention indices (RI). To overcome problems associated with the use of RI's based on homologous series determined with nitrogen-specific detectors, we have developed an RI reference system based on molecular masses and retention times of nitrogen-containing compounds. The standards chosen are easily available in highly purified form and can be detected by the unmodified nitrogen-specific detector. By using temperature programming, we can obtain a linear relationship between the molecular masses of standards and their retention times. Used in conjunction with microcomputer data handling, this screening system is rugged and reliable, operating 22 h per day. In the past two years, we have screened greater than 3000 samples (blood, serum, urine, gastric lavage) without major problems.
