Calibration Gases
The 800 system requires two gases to calibrate the pCO
2
and pO
2
sensors, Cal Gas
and Slope Gas.
Cal Gas provides the calibration point for both pCO
2
and pO
2
sensors during one-
and two-point calibrations. Cal Gas contains 5.00 ±0.03 mol% carbon dioxide and
12.00 ±0.03 mol% oxygen balanced with nitrogen. Cal Gas is NIST traceable.
Slope Gas provides the slope point for pCO
2
and pO
2
sensors during two-point
calibrations. Slope Gas contains 10.00 ±0.03 mol% carbon dioxide balanced with
nitrogen. Slope Gas is NIST traceable.
Compressed gas tanks can explode if mishandled. To prevent
personal injury or damage to the tank, observe the following precautions when
handling the tanks:
S Secure tanks to a wall, a bench, or the floor, or place them in a tank base support
stand.
S Use calibration gases only for the calibration of clinical and research
instruments. Do not dispense these gases for drug use.
S Do not drop tanks, do not allow tanks to strike each other, and do not subject
tanks to other strong shocks.
S Do not drag, roll, or slide tanks. Use a suitable hand truck to move tanks.
S Do not tamper with safety devices in regulators or tanks.
S Do not puncture the tanks. Tank contents are under pressure.
S Do not use or store tanks near heat or open flame.
S Do not expose tanks to temperatures above 54°C (130°F) because contents can
vent or explode.
S Do not dispose of tanks in a fire or an incinerator. Follow the disposal
instructions printed on the tanks.
