Section 2 Introduction
2.1 Purpose of This Manual
The purpose of this manual is to document the operating instructions for the URG-3000N.
2.2 Introduction
A drawing of a URG-3000N Sequential Particulate Speciation
System is shown here. The sampler consists of one Module
C, one Controller, one Stand, one Stand Rain Shield and one
36” Inlet Tube (the inlet tube is not shown in this illustration).
There may also be an optional collocated Module C and
Stand. The controller contains the timer, the keypad, and
other electronic equipment required to operate the sampler.
The stand contains the pump and flow controller. The
Module C collects PM
2.5
particles on quartz filters. These
filters are analyzed for organic and elemental carbon using
Thermal Optical Analysis Method (TOA).

Overview
The standard URG-3000N Sequential Particulate Speciation System configuration is shown above. Each
site will have a Module C that collects PM
2.5
samples and a Controller and a Stand. The lower portion of
the stand contains the vacuum pump as well as the mass flow controller to provide active volumetric flow
control. An additional Collocated Module C can be included in the configuration which would require a
Stand containing a vacuum pump and mass flow controller.
