Seek analysis methods and instruments for trace chlorine in the gas phase

The laboratory has a coulometer, but its detection range is relatively high, and with low sample concentrations, the error is significant. Now, analysis methods and instruments at the ppb level (which should represent trace or very small amounts) are needed. I was wondering if anyone here could lend a hand and assist me? ! ! Thank you so much! According to some literature, the Hubei Chemical Research Institute has gas-phase chlorine analysis instruments capable of detecting concentrations at the ppb level; it would be even better if we could get the help of those working at the institute! ! ! Thank you first!
