Patent ID: 6923847

Claim:
A liquid separator for a gas analyzer, said liquid separator comprising: a closed container including a sample inlet port, a sample outlet port, and a low pressure port; said container defining a liquid collection chamber and a liquid trap filter chamber, said liquid trap filter chamber including an inlet compartment interposed between said sample inlet port and said sample outlet port for receiving a gas sample introduced into said sample inlet port, said inlet compartment having an upper outlet communicated with said sample outlet port and a lower outlet communicated with said liquid collection chamber; a first liquid trap filter element, said first filter element being a thin, generally flat member contained and supported within said inlet compartment, interposed between said sample inlet port and said sample outlet port for separating liquid from the gas sample, liquid separated from the gas sample passing through said lower outlet to said collection chamber, said first filter element oriented vertically within said inlet compartment to maximize active surface area of said first filter element; said liquid trap filter chamber further including an outlet compartment interposed between said collection chamber and said low pressure port, said outlet compartment having an inlet communicated with said collection chamber and an outlet communicated with said low pressure port; and a second liquid trap filter element, said second filter element being a thin, generally flat member that is separate from said first filter element, said second filter element contained and supported within said outlet compartment interposed between said inlet and said outlet of said outlet compartment, said second filter element oriented vertically within said outlet compartment to maximize active surface area of said second filter element.
