Instrument Problems
If the instrument does not appear to be hampered by gas leaks, contamination,
excessive sampling gas temperatures and pressures, or electrical noise, refer
to Table B–1 before contacting your service representative.
Isopropyl alcohol can be hazardous. Follow all safety precautions
when in use and thoroughly wash hands prior to eating.
Never rub an optical surface, especially with dry tissues, as this
can mar or scratch the coated surface.
