ing upon the size of the battery. Since the ta7000R needs less than 5A of
current, the UPS battery pack can be relatively small.
The ta7000R needs a separate actuator gas in order to run properly. Please
refer to this section in the Specifications pages for detailed gas specifica-
tion.
Ultra High Purity (UHP) regulators and gauges are suggested for all in-
coming gas streams

Carrier gas should always flow through the Reduction Gas Analyzer.
Do not use an automatic shut-off valve for the sample/carrier gas

supply that would stop flow in event of power failure. It is essential
to always have flow through the RGD to prevent mercury build-up in
the photometer cell and on the cell windows. Mercury build-up will
decrease sensitivity of the detector. We recommend installing a spare
carrier gas cylinder into the carrier gas supply line for the RGD. The
spare cylinder can be plumbed in through a tee in the line. Use a
shut-off valve to isolate the spare cylinder when not in use. This extra
cylinder provides a safety margin in order to maintain flow through
the analyzer. Immediately order a new cylinder when the spare begins
to be used.

Use Cajon VCR fittings with gaskets to connect to UHP regulators.
CAUTION
Do not use pipe thread fittings since they are not clean and are not
leak-tight for trace gas analysis.
