Revision B.005
U.S. EPA Reference Method Designations
RFPS-0498-118 and RFPS-1298-127
Notice is hereby given that the U.S. Environmental Protection Agency (EPA) in
accordance with 40 CFR 40 Part 53 has designated a reference method for measuring
mass concentrations of particulate matter as PM-2.5 in ambient air. The reference
method is a gravimetric method which uses a specially designed PM-2.5 sampler for
particle collection. The designated method is as follows:
RFPS-0498-118 “Rupprecht & Patashnick Company, Incor-
porated Partisol-Plus Model 2025 PM-2.5 Sequential Air
Sampler” operated with software version 1.003 or 1.100, for
continuous sample periods, in accordance with the Model
2025 Instruction Manual and with the requirements and
sample collection filters specified in 40 CFR Part 50 Appen-
dix L.
Notice is hereby given that the U.S. Environmental Protection Agency (EPA) in
accordance with 40 CFR Part 50 has designated a new reference method for measuring
mass concentrations of particulate matter as PM-10 in ambient air. The new reference
method is a gravimetric method which uses a specially designed PM-10 inlet,
configured as a PM-10 reference method, for particle collection. The designated
method is as follows:
RFPS-1298-127 “Rupprecht & Patashnick Company Partisol-
Plus Model 2025 PM-10 Sequential Air Sampler” with
PM-10 inlet, configured as a PM-10 reference method, and
operated for 24-hour continuous sample periods in accor-
dance with the Model 2025 Instruction Manual and with the
requirements specified in 40 CFR Part 50, Appendix J or
Appendix M.
These methods are available from Rupprecht & Patashnick Company, Inc. (R&P), 25
Corporate Circle, Albany, New York 12203.

Revision B.005
Repair of instrumentation manufactured by Rupprecht & Patashnick Co., Inc. (R&P)
should only be attempted by properly trained service personnel, and should only be
conducted in accordance with R&P system documentation. Do not tamper with this
hardware. High voltages may be present in all instrument enclosures. Use established
safety precautions when working with this instrument. Instrument is supplied with a
grounded three-prong plug designed for outdoor use. When operating the instrument
outdoors, be sure that it is plugged into a properly rated exterior (outdoor) outlet.
The Partisol-Plus stand must be anchored when installed outdoors to prevent tipping
of the sampler and/or stand in high winds.
Some assembly of the inlet and WINS impactor is required for installation and regular
maintenance. Be careful to avoid pinching your fingers between the assembly parts
when assembling the WINS impactor or inlet.
Never place your hands or fingers in the filter exchange mechanism. Refer to the
Partisol-Plus Model 2025 Sequential Air Sampler Service Manual (September 1998,
Revision B) for instructions on clearing a filter jam.
The seller cannot foresee all possible modes of operation in which the user may
attempt to utilize this instrumentation. The user assumes all liability associated with
the use of this instrumentation. The seller further disclaims any responsibility for
consequential damages. Use of this product in any manner not intended by the
manufacturer will void the safety protection provided by the equipment, and may
damage the equipment and subject the user to injury.

Warranty (U.S.)
Unless otherwise agreed upon in writing by authorized personnel of Rupprecht &
Patashnick Co., Inc. (R&P) and the purchaser, the following warranty shall be in force
for equipment sold and operated in the United States of America.
R&P warrants that the R&P-supplied equipment shall be free from defects in material
or workmanship for a period of three-hundred and sixty-five (365) days after the date
of shipment. Subject to the conditions of this provision, R&P agrees to repair or

SECTION 1: INTRODUCTION PAGE 1-1
Revision B.003
Section 1: Introduction
The Partisol-Plus Model 2025 Sequential Air Sampler (Figure 1-1) is designed to meet
the regulatory monitoring requirements for PM-2.5 (40 CFR Part 50 Appendix L) and
PM-10 (40 CFR Part 50 Appendix J or Appendix M) and other particulate sampling
methods in the U.S., Europe and other countries.
This sampling platform holds the U.S. Environmental Protection Agency (EPA)
reference designation for the sampling of PM-10. Many of the design features adopted
by the U.S. EPA in the PM-2.5 Federal Reference Method were first introduced in a
reference-designated air sampling method designed by Rupprecht & Patashnick Co.,
Inc. in its original Partisol Sampler. These include the following:
• A flow rate of 1 m³/h through a single filter
• The use of standard 47 mm sample filters with a filter exchange mechanism
• Full microprocessor control and data handling
• Active volumetric flow control.
The Partisol-Plus Sampler can be configured to operate with a variety of inlet systems,
including the U.S. EPA WINS inlet-based reference PM-2.5 method, and PM-10, PM-
✔ The Partisol-Plus
Sampler builds upon
features first introduced
with the original Partisol
PM-10 Air Sampler.

2.5 (using a cyclone inlet), PM-1 and TSP (total suspended particulate matter) inlets.
A filter storage and exchange system allows the unit to operate for up to 16 days of
daily sampling between site visits. The Partisol-Plus system samples particulate matter
onto 47 mm diameter filters that are available in a wide variety of materials, many of
which are suitable for post-collection analysis.
Internal data storage and data input and output features allow meteorological data and
information from other external sources to be averaged and stored. Built-in sensors
measure ambient conditions, including temperature, atmospheric pressure and relative
humidity.
The Partisol-Plus Sampler allows users to define various sampling programs, in addition
to the standard 24-hour, midnight-to-midnight implementation. Conditional sampling
can be based upon information received from external sources in the form of analog
input levels.
The sampler records information by exposed filter (filter data), 5-minute period
(interval data) and by meteorological values and information received from other
sources (input data) at user-defined intervals.
The unit computes sampled volumes in both volumetric and standard terms to comply
with different regulations around the world.
1.1. ADVANCED F EATURES
The following is a list of some of the advanced features contained in the Partisol-Plus
Sampler:
• Automatic filter changing system with a capacity of up to 16 filters
between site visits.
• Operational simplicity, performance audits and stored data retrieval are
made possible through an embedded microprocessor and menu-driven
software.
• An active, volumetric flow-control system maintains a constant volumet-
ric flow rate at the level specified by the user (default of 16.7 l/min) by
incorporating a mass flow controller and ambient temperature and
pressure sensors. Sampled volumes are reported in volumetric and
standard terms. The sampler uses a reliable sample pump.
✔ Filter cassette maga-
zines simplify filter
exchange and transporta-
tion, and minimize the
chances of contamination.
