The Sievers ^® Nitric Oxide Analyzer (NOA 280i) offers the most versatile
detection system for Nitric Oxide (NO) analysis. Employing GE
Analytical Instruments highly sensitive, ozone-chemiluminescence
technology, the NOA 280i has unsurpassed versatility for liquid and
exhaled breath NO measurement.
With over 800 publications using the Sievers Nitric Oxide Analyzer,
the NOA has proven to be the instrumentation of choice by researchers
worldwide.

Liquid Samples
The NOA 280i measures nitric oxide, nitrite, nitrate or nitrosothiols in
most biological samples. Concentrations, ranging from low nanomolar to
millimolar levels, can be measured in sample volumes ranging from a few
microliters to several milliliters.

Exhaled Breath Samples
Exhaled nitric oxide can easily be measured with the NOA 280i. Fast response time and low sample flow rates allow for measurement of exhaled NO in humans and animals.
