Test Report: 936/21242468/A dated 19 February 2019

Initial certification: 22 July 2019

Expiry date: 21 July 2024

Publication: BAnz AT 22.07.2019 B8, chapter III number 1.1

Approved application The certified AMS is suitable for continuous ambient air monitoring of nitrogen oxides (sta-tionary operation). The suitability of the AMS for this application was assessed on the basis of a laboratory test and a seven-months field test. The AMS is approved for an ambient temperature range of 0 °C to +30 °C. The notification of suitability of the AMS, performance testing and the uncertainty calculation have been effected on the basis of the regulations applicable at the time of testing. As changes in legal provisions are possible, any potential user should ensure, in consultation with the manufacturer, that this AMS is suitable for monitoring the AMS readings relevant to the application. Any potential user should ensure, in consultation with the manufacturer, that this AMS is suitable for the intended purpose. Basis of the certification This certification is based on:

Test report no. 936/21242468/A dated 19 February 2019 issued by TÜV Rheinland Energy GmbH

Suitability announced by the German Federal Environment Agency (UBA) as the relevant body

The ongoing surveillance of the product and the manufacturing process



Publication in the German Federal Gazette: BAnz AT 22.07.2019 B8, chapter III number 1.1, UBA announcement dated 28 June 2019:

AMS designation:

Model 405 nm for NO, NO2 and NOx

Manufacturer:

2B Technologies, Boulder, USA

Field of application:

For the continuous measurement of nitrogen oxide concentrations from stationary sources in ambient air

Measurement ranges during performance testing:

Component Certification range Unit

Nitrogen monoxide 0–1 200 µg/m³

Nitrogen dioxide 0–500 µg/m³

Software version:

Version 36B

Restriction:

None

Notes:

1. The test report on performance testing is available on the internet at www.qal1.de.

2. As the measuring system does not provide password protection, it has to be mounted in a lockable cabinet.

3. Equivalence to the reference method in accordance with the requirements of the Guide to the Demonstration of Equivalence of Ambient Air Monitoring Methods was demonstrated.

Certified product This certification applies to automated measurement systems conforming to the following de-scription: The Model 405 nm ambient air monitor is a continuous nitrogen oxide analyser. The instru-ment uses direct UV absorption as a measuring principle. It was designed for the continuous measurement of NO, NO2 and NOx in ambient air.

The model 405 NO2/NO/NOx monitor is designed to measure atmospheric nitrogen dioxide (NO2), nitrogen oxide (NO) and NOx (NO + NO2) in a dynamic range from just a few ppb up to 10 ppm for NO2 and 2 ppm for NO based on the detection of visible light at a wave length of 405 nanometres (nm).

The model 405 inside the analyser uses the absolute method to measure NO2 on the basis of Beer-Lambert law. NO2 measurement relies on a conventional absorption method. NO2 is analysed at a UV light wave length of 405 nm. The necessary measurement path length of 2 m is realised by using a measurement cell with a tube design which facilitates low volumes and fast gas replacement.

Nitrogen oxide is measured by measuring UV light intensities with and without adding ozone for oxidising NO to NO2. As described in more detail below, the result is a “semi-direct” measurement of NO in that the NO concentration is output directly and not based on subtrac-tion of NO2 concentration from a total NOx concentration. Instead, the NOx concentration is computed as the sum of the measurements of NO2 and NO.

The pump sucks in sample air through the instrument at a constant flow rate of 1.5 l/min. The NO2 scrubber valve alternately bypasses and sends the sample air through a heated NO2 scrubber to remove all NO2 in the sample. The NO2-scrubbed or unscrubbed air passes through the reactor volume and the DewLineTM Nafion Tubes, through the optical cell and through the cell flow meter. Alternate switching of the NO2 scrubber valve once every 5 sec-onds allows the measurement of a light intensity in the absence (Io) of NO2 and presence (I) of NO2. The Beer-Lambert Law is then used to calculate the concentration of NO2 from I and Io.

Nitrogen oxide is measured by bypassing the NO2 scrubber and measuring the light intensity while adding (I) or not adding (Io) ozone to convert NO to NO2 according to the well-known reaction:

NOx is computed from the measurement of NO and NO2.



General remarks This certificate is based upon the equipment tested. The manufacturer is responsible for en-suring that on-going production complies with the requirements of the EN 15267. The manu-facturer is required to maintain an approved quality management system controlling the manufacturing process for the certified product. Both the product and the quality manage-ment system shall be subject to regular surveillance. If a product of the current production does not conform to the certified product, TÜV Rhein-land Energy GmbH must be notified at the address given on page 1. A certification mark with an ID-Number that is specific to the certified product is presented on page 1 of this certificate. This document as well as the certification mark remains property of TÜV Rheinland Energy GmbH. Upon revocation of the publication the certificate loses its validity. After the expiration of the certificate and on request of TÜV Rheinland Energy GmbH this document shall be re-turned and the certificate mark must no longer be used. The relevant version of this certificate and its expiration date are also accessible on the in-ternet at qal1.de.

Document history
