Series 5400 Ambient Carbon Particulate Monitor
The Series 5400 Ambient Carbon Particulate Monitor is an automatic speciation analyzer of suspended particulate matter. It performs measurements of the elemental and organic carbon contained in suspended particulate matter at averaging times as short as one hour. Its thermal-CO2 analysis technique is similar to that used in many analytical laboratories to measure carbon particulate concentration.
Using a direct thermal-CO2 technique patented by Thermo, the instrument differentiates between organic and elemental carbon particulate matter by oxidizing collected samples at an intermediate temperature and at a high final burn temperature. When operated at a two-hour cycle, the user can set up the monitor to perform up to three sample oxidations at intermediate temperatures prior to the final burn.

ChemVol® High Volume Cascade Impactor
The ChemVol Model 2400 High Volume Cascade Impactor is a high volume sampling device that simultaneously collects numerous particle size fractions from ambient air. Multiple sampler stages permit the classification of ambient particulate matter (PM) into its coarse, fine, accumulation and ultra fine modes over short (multiple hour) or multi-day collection periods. Particulate matter in different size ranges is impacted onto a polyurethane foam (PUF) substrate. The collection surface is inert, prevents particle bounce, provides a high mass loading capacity, and is easily removable. The PUF material and the collected particulate matter are removed from the sampler, and the particles are analyzed in a laboratory.

- Major System Components
- Sampler Configuration
- Particle Collection Mechanism
Passive Samplers
Radiello® Model 3310 Passive Sampling System
The Radiello Passive Sampling System provides an effective means of sampling gases for industrial, indoor, outdoor, and personal exposure applications. As a passive sampler, the device does not require any electric power. Its light weight and small size, high and constant sampling rate, and well-documented sampling and analytical procedures make it the ideal platform for determining gaseous concentrations (see list of sampled gases). The Radiello system contains a patented geometry developed by the Fondazione Salvatore Maugeri of Padova, Italy, that results in very high selectivity and sensitivity, and gas sampling rates. The Radiello system is included in the ISO 16200-2 standard for the sampling and analysis of volatile organics, and has played a major role in a number of major international projects for assessing the concentration of benzene and ozone precursors.
Features:
- Sampling and Analysis
- In-Field Sampler Preparation
ChemPass® Model 3400 Personal Sampling System
The ChemPass Model 3400 Personal Sampling System is a modular device that provides high-quality samples of multiple pollutants simultaneously. It can provide valuable personal and indoor exposure information on concentrations of particulate matter (PM) and related pollutants. Such detailed information is generally not obtainable from monitors housed in conventional air quality monitoring stations. Configured as a multi-component system, the ChemPass unit contains six sampling devices connected to a high capacity battery-powered pump, all attached to a belt-and-suspenders mounting system. Single-pollutant configurations are also available in which a single PM-2.5 or PM-10 sampler is attached to a pump operating at 4 l/min. The sampling apparatus is worn in an individual’s breathing zone to ensure representative sampling. The pump located on an individual’s mounting belt provides the vacuum necessary to support the four active sampling devices contained in the multi-component system.
Beta Absorption Particulate Monitors
FH 62 C14 Series Continuous Ambient Particulate Monitor
The FH 62 C14 Continuous Ambient Particulate Monitor measures the mass concentration of suspended particulate matter (e.g., TSP, PM10, PM2.5, PMC and PM1) by use of beta attenuation. In addition, the ambient radioactive influence of natural Radon (Rn-222) gas is measured as a refinement step toward better sensitivity at lower ambient particulate concentrations.
Features:
- New technology that provides continuous "real-time" measurement by a C14 monitor
- Radon gas activity measurement eliminates interference of natural airborne radioactivity
- Control and data exchange over two serial interfaces possible
- Storage of half-hour average concentrations over a whole year
- User selectable reporting of mass concentration based on standard or actual flow rate
- Processor controlled calibration of all sensors
- Insensitive to vibration and diurnal temperatures
