The purifier is offline unless used for optional troubleshooting or zeroing. Customers can also use their own zero gas.
“ The purifier included with the DF-700 is required for the analyzer to work”
The DF-700 series performs a curve fit and advanced signal processing that compensates for electrical and system noise.
“ The DF-700 series is susceptible to noise”

CRDS still experiences drift and noise. Its zero reference isn’ t absolute due to system noise, laser instability, detector drift, and mirror degradation.
“ CRDS doesn’ t need zero calibrating as this is set at the factory”
