measurement of nitrite, nitrate/nitrite and nitrosothiols in biological fluids, cell
culture media, and other liquid samples. A schematic of the 280i NOA is shown in
Figure 1-1 and consists of the following major components:
• Sampling Inlet Systems
• Sample Flow Control Device
• Ozone Flow Control Module
• Ozone Generator
• Chemiluminescence Reaction Chamber and Optical Filter
• Photomultiplier Tube and Cooled Housing
• Vacuum Pump and Chemical Trap
• Front Panel Display
• Four Button Keypad
• PMT Amplifier
• Power Supply
• Analog to Digital Converter
• Microprocessor and Output Electronics
• Analog, Printer, and RS-232 Outputs
• Exhalation Pressure Transducer
• Optional Thermal Mass Flowmeter
Sample Inlet Systems
The NOA 280i has a
complete range of sample
inlet systems for
measurement of NO and its
reaction products including:
• Gas Sampling Kit for
measurement of gas-
phase NO. The kit
includes a Nafion
®
drier,
0.45 µm particle filter,
PVC sampling lines with
