Patent ID: 8829914

Claim:
A dual ionization source ionization detector body comprising: an enclosed elongated chamber, said enclosed elongated chamber having a chamber first end and a chamber second end; a first ionization source, said first ionization source positioned in said enclosed elongated chamber adjacent said chamber first end, a column gas inlet piping into said enclosed elongated chamber between said first ionization source and said chamber second end; a second ionization source, said second ionization source positioned in said enclosed elongated chamber adjacent said chamber second end, an outlet piping from said enclosed elongated chamber positioned between said column gas inlet piping and said second ionization source; a first combined bias/collecting electrode having a first combined bias/collecting electrode end exposed to said enclosed elongated chamber between said column gas inlet piping and said outlet piping; and a second combined bias/collecting electrode having a second combined bias/collecting electrode end exposed to said enclosed elongated chamber between said first combined bias/collecting electrode end and said second ionization source.
