Abstract

An interface for the analysis of liquid sample having carbon content by an accelerator mass spectrometer including a wire, defects on the wire, a system for moving the wire, a droplet maker for producing droplets of the liquid sample and placing the droplets of the liquid sample on the wire in the defects, a system that converts the carbon content of the droplets of the liquid sample to carbon dioxide gas in a helium stream, and a gas-accepting ion source connected to the accelerator mass spectrometer that receives the carbon dioxide gas of the sample in a helium stream and introduces the carbon dioxide gas of the sample into the accelerator mass spectrometer.

Claims (14)

1. An interface apparatus for the analysis of liquid sample having carbon content by an accelerator mass spectrometer comprising:

a wire,

spaced paint droplets on the wire,

a droplet maker for producing droplets of the liquid sample and placing said droplets of the liquid sample on said spaced paint droplets on said wire,

a system that converts the carbon content of said droplets of the liquid sample to carbon dioxide gas in a helium stream,

a gas-accepting ion source connected to the accelerator mass spectrometer that receives said carbon dioxide gas of the sample in a helium stream and introduces said carbon dioxide gas of the sample into the accelerator mass spectrometer for analysis, and

a system for moving said wire from said droplet maker to said system that converts the carbon content of said droplets of the liquid sample to carbon dioxide gas in a helium stream.

2. An interface apparatus for the analysis of liquid sample having carbon content by an accelerator mass spectrometer comprising:

a wire,

spaced solder droplets on the wire,

a droplet maker for producing droplets of the liquid sample and placing said droplets of the liquid sample on said spaced solder droplets on said wire,

a system that converts the carbon content of said droplets of the liquid sample to carbon dioxide gas in a helium stream,

a gas-accepting ion source connected to the accelerator mass spectrometer that receives said carbon dioxide gas of the sample in a helium stream and introduces said carbon dioxide gas of the sample into the accelerator mass spectrometer for analysis, and

a system for moving said wire from said droplet maker to said system that converts the carbon content of said droplets of the liquid sample to carbon dioxide gas in a helium stream.
