GE P&W Ultrapure and Drinking Water TOC Analyzers - Sievers Nitric Oxide Analyzer (NOA 280i) - Manual (Page 3)

Other Gas Applications
Use the NOA 280i to measure gas-phase NO in the GI
tract during endoscopy. The NOA 280i can also be used
to measure NO directly in the airways during bron-
choscopy.
Exhaled Breath Accessories
On-Line NO Breath Kit
Use the On-Line NO Breath Kit to accommodate flow
rates from 30 to 250 mL/sec, to meet the American
Thoracic Society’s (ATS) and the European Respiratory
Society’s (ERS) recommendations for on-line exhaled
NO measurement.
Thermal Mass Flowmeter
Use the Thermal Mass Flowmeter with the On-Line
NO Breath Kit for direct measurement of exhalation
flow rate.
Off-Line Sampling Kits
The Off-Line Sampling Kits include an inspiratory gas fil-
ter to reduce the concentration of NO in inspired air to <5
ppb. Two different bag collection kits are available.
Following ATS recommendations for off-line exhaled
NO, use the ATS Compliant Bag Collection and
Sampling Kit to collect the entire vital capacity at a flow
rate of 350 mL/sec. The ATS Kit uses 12 L Mylar bags.
Use the Bag Collection and Sampling Kit to collect off-
line exhaled NO at 50 mL/sec, the same conditions the
ATS recommends for on-line sampling. This kit employs
the dead space volume discard technique with subse-
quent collection of exhaled breath in 1.5 L Mylar bags.
Calibration Kit
The Calibration Kit includes a Zero Air Filter,
to generate air containing <1 ppb NO from room air, the
calibration gas, and a low flow regulator.
Calibration Gas
A small, lightweight, disposable cylinder of 45 ppm NO
in N
2
, which provides sufficient NO calibration gas for
three to four months of operation.
Zero Air Filter
The Zero Air Filter removes NO from ambient air
providing a clean (<1 ppb nitric oxide) air source for
calibration.
Bacterial/Viral Filters
The single-subject, disposable Bacterial/Viral Filters,
with >99.9% bacterial and viral filtration efficiency, are
used with the On-Line NO Breath and the Bag
Collection and Sampling Kits
