The construction and evaluation of a low cost, easily demountable interface to couple capillary gas chromatography to inductively coupled plasma mass spectrometry detection is described. Using this interface, the capillary column can be maintained at a high temperature through to the tip of the torch injector using a transfer line heated by a combination of hot argon and electrical resistance. The interface is suitable for analytes with boiling points up to 230°C, allowing for the analysis of low and high boiling analytes in a single injection. The system was evaluated by the determination of the butyltin species in a marine sediment CRM using conventional calibration with tripropyltin dichloride as the internal standard and the measurement of methylmercury in a tuna fish CRM via species-specific isotope dilution analysis. Detailed information on the design and construction of the interface are included to facilitate its construction and use by other workers. |
