Performance Assurance Tests - Checking and Calibrating the Gas Analyzer
Kit Leak Test Procedure:
Form a loop with the leakage test kit as shown in the picture below. Use the female luer thread/luer
1
slip to attach the long tubing to the watertrap tubing.
Connect a syringe to the 3-way stopcock and a digital pressure indicator to the open tubing.
2
Draw at the syringe until the digital pressure indicator shows 210 mbar below ambient pressure.
3
Close the 3-way stopcock to syringe and wait 5-10 seconds. In this time, the overall pressure
4
should stabilize at approximately 200 mbar below ambient pressure.
After 1 minute, check the pressure. The pressure should not increase more than 5 mbar in 1
5
minute for the test to pass.
6 If this test fails, exchange the leakage test kit. If this test passes, exchange the gas analyzer.
Expected result for the Leak Check (not for the Kit leak test):
After 1 minute, check the pressure. The pressure should not increase more than 80 mbar in 1 minute
for the test to pass.
If this test fails, make sure that there are no leaks in the setup and rerun the test. If it still fails, the gas
analyzer has an internal leakage and needs to be replaced.
