Product Detail
The Series 5400 Monitor is a network-ready instrument that automatically determines the level of low- and high-temperature carbon particulate matter in ambient air. The device utilizes an automatic thermal-CO2 analysis technique patented by Thermo to oxide carbon particulate matter collected on an impactor. The unit differentiates between "organic" and "soot" carbon by oxidizing the collected particles at an intermediate temperature (340 C default) before conducting a full burn at 750 C. As is the case with other advanced products from Thermo, the user has significant control over instrument operating parameters, including the temperature of the intermediate burn. In its default setup, the monitor generates a new set of data points every hour.
Features
German EPA approved for the measurement of elemental carbon in particulate matter.
Measurement of carbon by automatic, patented thermal-CO2 method. The default intermediate and final burn temperatures are 340 and 750 C, respectively.
Dual collector/furnace design provides independent hourly measurement of the organic and soot carbon particulate concentration. This allows for simultaneous collection on one collector while the instrument performs its analysis on the second collector.
User-selectable temperature for the differentiation between organic and soot carbon (340 C default).
Two-phase instrument cycle consists of collection and analysis. The default collection period is one hour. The user may also specify longer collection periods such as 2, 3, 4, 6, 12 or 24 hours.
Collection by impaction minimizes artifact formation. User control over collector temperature during sample collection. Heater control for sample tube is also available.
Afterburner oxidizes materials driven from the collector during the sample analysis phase.
Choice of sample inlets that operate at 1 m3/h (approximate): PM-10, PM-2.5, PM-1, TSP.
User-programmed operation allows for up to three intermediate temperature plateaus before the final burn. The user may specify both the temperature and dwell time for each plateau.
Definitive audit and calibration methods. Automatic leak check and CO2 audit (zero and span) when bottled N2 and CO2 span gas are connected to the monitor. This can be performed on call, or on a daily or weekly basis. Software support for a multi-point calibration of the CO2 sensor using syringe-injected CO2.
Flexible viewing and entry of instrument parameters through a menu-driven user interface.
Advanced data handling features such as internal data logging, three user-defined analog or current outputs, and bi-directional RS232 communication capability.
