Partisol Model 2000-D Dichotomous Air Sampler

	PRODUCT DESCRIPTION The Partisol 2000-D Dichotomous Air Sampler by Thermo Fisher Scientific is a single-event particulate matter (PM) sampler that holds two filters for the simultaneous collection of the fine and coarse particles contained in PM-10. High quality molded Partisol-FRM style filter cassettes house the two 47mm filters used to collect the coarse and fine PM. Downstream from its PM-10 inlet, the unit contains a traditional virtual impactor for separating the coarse particles from the majority of the fine particles. Two independent mass flow controllers automatically maintain a constant 16.7 l/min volumetric flow rate through the PM-10 inlet, with a 1.7 l/min volumetric flow rate directed through the coarse particle sample filter and a 15 l/min flow through the fine particle sample filter. The Partisol Model 2000-D Dichotomous Air Sampler can be programmed to sample for any desired time period with user-defined start and end date/time input. The sampler provides run-time information such as total sample volume and performance diagnostics.

Regulatory Designations

Candidate USEPA method sampler for PM-10, PM-2.5 and PM-coarse size fractions.

Safety/Electrical Designations

• CE: 89/336/EEC - Electromagnetic Compatibility (EMC Directive), EN 61326:1997 + A1:1998 + A2:2001. 73/23/EEC - Low Voltage Directive (LVD), EN 61010-1:2001.
• UL- and CSA-equivalent approval.

Sampling Program

The user specifi es the starting and ending date and time of sample collection. The software stores user default settings to simplify the definition of sampling programs.

Sample Flow Control and Reporting

• Air flow through the sampler is provided by a proven low-maintenance vacuum pump.
• Activol^TM flow control system uses mass flow sensors and the measured ambient temperature and pressure to maintain constant volumetric flow rates. System flow rate is 16.7 l/min (1 m³/h).
• The sampler displays the current volumetric flow rates (l/min). For each filter exposed, the unit stores the total volume in volumetric m³.

Temperature/Pressure Measurements and Control

• The ambient temperature is measured continuously by an externallymounted temperature sensor housed in a solar radiation shield.
• The temperature of the collection filters is measured continuously within one cm of the center of the 47 mm filter.
• The ambient pressure is measured continuously by a sensor built into the sampler.
• The current and averaged values of the above measurements may be viewed on the instrument display.
• The filter compartment is ventilated continuously to ensure that the filter temperature is within 5 ⁰C of the ambient temperature.

Interval Data Storage

• One record of interval data is stored every five minutes, and includes the time and date, and five-minute averages of the ambient and filter temperature, ambient pressure, and sample flow rates.
• Interval data are recorded continually, even when the unit is not sampling.
• These records may be viewed on the display screen or downloaded directly into a PC through the RS232 connector.
• The device has a capacity of 12 days of interval data. Filter Data Storage
• One record of filter data is stored for each set of filters exposed in the Partisol Dichotomous Sampler. Each record includes a large amount of filter-related information, and exceeds USEPA requirements. This includes (but is not limited to) the filter-based minimums, averages, and maximums for temperatures and pressure. Flows are recorded as average flow rates, total volumes and the flows' percentage coefficient of variation. It also includes the largest temperature difference (with time and date stamp) between the ambient and filter temperatures, status condition(s), filter ID information, and a listing of up to 10 power interruptions.
• These records may be viewed on the display screen or downloaded directly into a PC through the RS232 port.
• The device has a capacity of 25 records of filter data.
