Notizen:
It is demonstrated that linear injection characteristics are obtained for a wide boiling point range sample using a temperature-programmed injector in combination with wide-bore fused silica columns. The applicability of the described combination for high temperature simulated distillation is described. The method, using external standardization, gives accurate and repeatable results for different types of samples in the boiling range between 50 and 750°C. The lifetime of the fused silica wide-bore columns was found to be acceptable, viz. over 80 temperature-programmed cycles between ambient and 430°C. Some comments are made on the accuracy of boiling points for normal alkanes.
