We provide a twenty-four hour turnaround on gas analysis • Available twenty-four hour turnaround
including: • Gas chromatography through remote sampling identifies
• Oxygen (trace nitrogen levels)
• Nitrogen (trace oxygen levels) a wider range of potential contaminants
• Nitrous Oxide (trace nitrogen and oxygen levels).Trace analysis
• Instrument calibration gases are NIST traceable
of the variable gases such as carbon dioxide, carbon monoxide, • We aim to provide accurate, consistent, reliable results…
methane, and total volatile hydrocarbons (TVHC)

Several commercial cleaning agents for oxygen service are
available, some of which are halogenated solvents containing
hydrocarbons. If you use these solvents for cleaning your medical
piping, we offer two test methods to check for trace contaminants
of halogenated hydrocarbons in the system after it has been
cleaned and then flushed,usually with nitrogen:
• On-site Detector Tubes: These are usually calibrated for a

particular chemical or chemicals.
• Gas Chromatography: Using our remote sampling system, we

are able to test samples in our lab on a gas chromatograph
which can specifically identify a wider range of potential
contaminants at parts per billion (ppb) levels, well below the
regulatory limit of 2 parts per million. Contact our chemists
for details.
