Attachment E Specifications for a Sulfur Dioxide Analyzer

Description: Sulfur Dioxide (SO2) Monitor for detecting and measuring SO2 in ambient air. The instrument shall be microprocessor controlled and use the Ultra-Violet (UV) fluorescence method of detection.

MINIMUM GENERAL SPECIFICATIONS

The SO2 analyzer must meet the following requirements:

A. Must have a U.S. Environmental Protection Agency (EPA) federal reference or federal equivalent method designation EQSA-0495-100.

B. The system must contain the following components:

i. Must be free-standing no larger than 7”H x 17”W x 24”D, and weight no more than 40 pounds.

ii. Must have standard 115-volt 60 Hz AC operation;

iii. The sample pump must be internal to the analyzer and flow rate controlled;

iv. Analog output to be 0-1 volt direct current;

v. Front panel USB connections for firmware upgrades;

vi. The Photomultiplier Tube (PMT) and all sockets and high voltage circuitry thereof, shall be of the highest quality;

vii. PMT temperature controlled for reduced noise;

viii. The sample inlet shall be a 0.25-inch Swagelok® compatible compression fitting;

ix. Analyzer must have easily viewed digital display with a touch screen interface;

x. The operational temperature range must be between 5 and 40ºC;

xi. The display should allow the operator to monitor levels, flows, alarms, temperature and pressure, trend data and voltages;

xii. Setup including zeroing, spanning, etc. should be accomplished using pushbuttons and the display;

xiii. Must have a RS-232 interface; and

xiv. Software and non-volatile random-access memory (RAM) storage shall allow the internal storage of a large number of 1-minute to 5-minute average SO2 samples and a record of alarms and out of limits conditions.

C. Must have user selectable dual ranges of 0-50 ppb and 0-20,000 ppb;

D. Minimum detection limit of less than 0.4 parts per billion;

E. Zero noise of less than 0.2 ppb;

F. Span noise of less than 0.5% of reading (RMS) above 50 ppb;

G. Precision of less than 0.5% of reading above 50 ppb;

H. Linearity should be ±1 percent of full scale;

I. Zero drift should be less than 0.5 ppb over 24 hours;

J. Span drift should be less than 0.5% of full scale over 24 hours;

K. Response time less than 120 seconds to 95% of scale;

L. Sample flow rate of 0.6 to 0.7 SLPM;

M. Measurements should be temperature and pressure compensated;

N. Span and zero adjustable and off-setable; and O. The operating system shall be capable of being updated.

P. Must have hardware specific remote access software that allows for remote connection with virtual interface and data downloading capabilities.
