8. EPA PROTOCOL CALIBRATION

In order to insure that high quality, accurate measurement information is obtained
at all times, the analyzer must be calibrated prior to use. A quality assurance
program centered on this aspect and including attention to the built-in warning
features of the analyzer, periodic inspection, regular zero/span checks and routine
maintenance is paramount to achieving this.
Calibration, on the other hand is the process of adjusting the gain and offset of the
M300E to agree with some recognized standard.
The USEPA strongly recommends that you obtain a copy of the publication Quality
Assurance Handbook for Air Pollution Measurement Systems Volume 2: Part 1,
Ambient (abbreviated, Q.A. Handbook Volume II). This manual can be purchased
from:
USEPA Order Number: EPA454R98004; or NTIS Order Number:

PB99-129876.
National Technical Information Service (phone 800-553-6847) or Center for

Environmental Research Information or the U.S. Government Printing
Office at http://www.gpo.gov.
The Handbook can also be located on line by searching for the title at

Special attention should be paid to Section 2.6 which covers CO analyzers of this
type. Specific regulations regarding the use and operation of ambient CO analyzers
can be found in Reference 1 at the end of this Section.
A bibliography and references relating to CO monitoring are listed in Section 8.2.
8.1.1. M300E Calibration – General Guidelines
The reliability and usefulness of all data derived from any analyzer depends
primarily upon its state of calibration. In this section the term dynamic calibration
is used to express a multipoint check against known standards and involves
introducing gas samples of known concentration into the instrument in order to
adjust the instrument to a predetermined sensitivity and to produce a calibration
relationship. This relationship is derived from the instrumental response to
successive samples of different known concentrations. As a minimum, three
reference points and a zero point are recommended to define this relationship. The
calibration gas used must be traceable to a NIST standard.
