PRINCIPLE OF OPERATION FOR CONTINOUS MEASUREMENT OF PM10 OR PM2.5

Model LSPM10 is an instrument designed for the continuous monitoring of particulate, using the principle of orthogonal nephelometry. A constant flow controlled pump draws ambient air through the size selective sampling head of choice (PM10 or PM2.5) into the instrument, where particle concentration is derived by measuring the light scattered from an excitation beam. Using a special collimator device, the light beam is focussed in a spectral narrow band into the detector. LSPM10 uses a photo multiplier tube, a well-established technology, very stable and with good reliability. The signal is then output continuously to the microprocessor for data elaboration. Data are displayed as micrograms/nm3 on the front panel. The analyzer performs an automatic calibration of 20 seconds every 6 minutes. Potential drift is therefore compensated, ensuring high analysis stability.
The LSPM10 can be equipped with a gravimetric unit (16 membrane filters- 47 mm dia.). It is possible to run the analyzer without interruption and get the particulate samples, strictly in accordance with EN12341/98 standards. LSPM10 can be set as a constant flow sampler, archiving sampling time, total volume sampled, average pressure and temperature during the sampling. The gravimetric weighing can be compared with the analyser’s readings to check their accuracy. The LSPM10 is the best instrument to continuously monitor PM10 or PM2.5 particulate concentration by measuring the average of instantaneous values for each 6 minutes, the hourly averages and the 24 hours averages.

  • High precision collimation: The LSPM10 uses a system of grids for beam collimation. This unique technology provides a high optical throughput and the ultimate in stray light performance. There are no optical parts in contact with the sample.
  • Orthogonal configuration:.As any light concentration devices are not involved (filters, lenses etc), LSPM10 can assure perfect orthogonal beam conditions. The advantage of this strict orthogonal geometry is that response with respect to particle size is better suited to measurement of urban ambient aerosols.
  • Better Handling of Volatiles:LSPM10 operates with its inlet only a few degrees above ambient temperature thanks to the heat generated by the light source. There are no errors of underestimation of the measurements due to the loss of volatiles such as ammonium nitrate..

47 mm filter Sampler Device according to the Directive EN12341
The LSPM10 equipped with the sequential unit is a constant volume sampler. The LSPM10 is supplied with the FOX modl pump which can be set in two modes:
1) Pump mode: it acts at the constant flowrate of 38,3 l/min (used without Sequential unit).
2) Set mode : it can be set to command the sequential unit and store in memory the following data:
- Date and time of sampling start
- Date and time of sampling stop
- Date and time of starting of single sampling (for each filter)
- Data and time of stop of single sampling (for each filter)
- Display of the averafe flowrate normalized at 25°C, 1013 mBar
- Total sampling time
- Total normalized sample volume
- Flow normalization at standard values
- Input of standard sampling conditions (reference pressure and temperature)
- Average, minimum and maximum Pressure and temperature during sampling
- Flow normalization at standard values
- Maximum ?T during sampling
- Report of error
