The glass insert in stop-flow split injection

  • Guanghui Liu
  • Zhenxue Xin


In stop-flow split injection the careful choice of the experimental conditions is of great importance for accurate quantitation, the size of the gaseous sample plug and its position with respect to the column inlet and to the top of the insert during the evaporation period are critical to prohibit sample vapour overflow and aerosol splitting. The proper insert design is established. A sample volume of 0.5 μl is recommended in the practical application of the stop-flow method.
