• System designed for analysis of

permanent gases and organics

• Gas sample valve for sample

introduction

• Split inlet for injection volume

control and alternative injection

source

• Deans switch allows for heart

cutting permanent gases to

Molsieve column

• Dual detectors for simultaneous

analysis from two columns
