Recognizing that ambient air contains 209,000 ppm (20.9%) of oxygen, use of plastic sample tubing exacerbates the chance that an oxygen leak from outside air will taint the readings. A minute air leak can render a measurement useless. Usually, copper or stainless steel tubing is always the materials of choice.
