FAQ #7
Q. The Users Manual says to set my oven flow rate to 100 cc/min. Why?
A. The design of some KIN-TEK gas standards generators splits the carrier gas flow into two portions. One portion (oven flow) goes through the oven and sweeps across the permeation tube to pick up analyte gas permeated from the tube and carries it to a point where it combines with the other larger portion of carrier gas called the dilution flow. Using approximately 100 cc/min of oven flow ensures that the permeating analyte is being carried out of the oven and through the system.
KIN-TEK advises not to exceed 250 cc/min of oven flow and not to set less than 50 cc/min of oven flow.
