What is the flow rate necessary for the 9240/9245 Sodium Analyser if using a sample cooler?
9240 and 9245 Sodium Analyser Flow Rate
The flow rate of the sample entering into the analyser should be anywhere between 7 to 10 L/h per channel. The volume of sample flowing into the analyser is therefore anywhere between 7 to 10 L/h if you are not using the bypass circuitry, up to 28 to 40 L/h if you are using the bypass circuitry with a 4 channel analyser. In any case, the flow rate of the sample going into the measuring chamber and then “polluted” by the conditioning agent is 5 L/h. So to size the sample cooler, the best flow rate to use is 10 L/h per channel.
