What is a Batch Inlet?

A batch inlet allows the sampling of the gaseous area above the liquid sample. This area is called the headspace. The needle valve controls the rate of introduction of the headspace, into the mass spectrometer. The batch inlet requires that a DIP port is mounted on the mass spectrometer.

Batch Inlet Advantages

  • allows spectra of more volatile compounds to be obtained
  • minimum sample preparation

Batch Inlet Disadvantages

  • samples must be relatively pure
  • requires a valving system
