P10 gas regulators
« on: February 11, 2015, 12:47:22 am »
I would like to know what people are using for their P10 gas line regulators. Our SX100 is equipped with Air Liquide BS 300 3 SE S regulators (20 bar inlet max, 3 bar outlet max), but an attempt at googling does not reveal any information about this regulator. Another post on this forum mentions an Air Liquide BS 20-3-2,5  and I suspect a  Smith model 601  would also work.

Also, does anyone know of a source for a glass bubbler?

Can't help you with the gas bubblers, but I did have our shop make a few dozen high quality stoppers with the brass tube insert. The material is a Teflon polypropylene that doesn't react with the bubbler fluid.

On the gas regulators we used a Matheson flammable gas regulator. You can see it here I think:

I replaced the high pressure gauge with one that has an adjustable magnetic switch for low pressure warning connected to a modem that calls our engineer when it gets below 500 psi.

Can I ask what model of in line regulator you are running (located just next to the gas bubbler)?

You mean on the P-10 cylinder?

I was not very clear. On our SX100 there is the regulator on the P10 cylinder, and then another in-line regulator for each individual spectrometer at the back of the instrument.

Hi Jeremy
Not sure if its any help, but our SXFive uses Air Liquide regulators as well on the individual bubblers, model BS 20-3-2,5, exactly as you describe in your original post. Cant help you on the glass bubblers though.
