Oxygen generator with external compression of 40,000 units, equipped with an argon system; it also produces high-purity liquid oxygen (purity of 5 nines). Seeking advice

The argon column has an outlet and an inlet for the aerobic fraction; the process is basically as such. The current operating conditions are as follows: the distillate value is 7.8, the distillate volume is 53,000; the output from Tower 1 contains 92.8% oxygen, while the output from Tower 2 contains 99.2% argon with only 0.1 ppm of oxygen. My question is that deoxidation in the first tower is basically useless, while deoxidation in the second tower is too strong. I’ve never seen anything like this before; I’d appreciate it if experts could share their opinions.
First, it’s necessary to determine the accuracy of the analyzer~~ Then, check the design specifications to find out what the designed oxygen content in the gas exiting one of the towers is; perhaps that’s just how it’s designed~~ Hehe~~ As for the degree of distillation, it depends on the design ratios of the two towers~~
What is the distillate fraction specified in your manual?
The specified argon and oxygen content in the two towers is 99.2% above the limit; the analyzer should be checked first
