MSP Corporation Model 1000XP-B, SMS™ - Request a Quote

Scanning Mobility Particle Sizer, 10nm -500nm, 96 size bins

laser particle counterThe SMS samples aerosol for measurement at the rate of 0.3 liters per minute (L/min). 0.3 L/min of this flow is sampled directly into the DMA for particle size classification and particle counting by the CPC. The data are then sent to the internal, single-board computer for processing and storage. The instrument provides 12, 24, 48, & 96 channels of size resolution. The SMS is recipe-controlled, allowing the scientist, engineer, or system manager to create as many recipes as required for a variety of aerosol studies. These recipes are then stored in memory to be recalled at any time, thus ensuring the same instrument settings can be used for data collection each time a given recipe is put into use.

The SMS uses MSP designed Differential Mobility Analyzer (DMA) with 4D (4-Dimensional) Controls™ of airflow, high voltage, pressure compensation and temperature compensation to provide the most accurate sizing possible. Sheath flow for the DMA is recirculated to provide repeatable stable flow for improved DMA size response. Boltzmann equilibrium charge is established on the aerosol using a low level ionizing source. The CPC is of advanced MSP design that has solved the traditional problems of water condensation and collection in the saturator. A dual reservoir design ensures the condensate is collected into a separate reservoir to avoid mixing of condensed water with the working fluid in the working fluid reservoir. The CPC design features rapid warm-up and response for accurate aerosol measurement.

The photodiode detector is a solid state, low noise device. NIST PSL calibration spheres achieve calibration at 100.7nm and 269nm for the DMA. The DMA and CPC are small, compact devices allowing the entire system to be placed within a small enclosure that is compact in size (12” x 15” x 18”) and light in weight (~35lb). The SMS small compact design allows easy transport between lab and field locations for the research scientist and application engineers requiring wide range particle sizing and counting.

The SMS is the only spectrometer in the world with DMA and CPC technology combined into one single system with integrated display and software. Operation is recipe driven, minimizing set up errors and ensuring repeatable data collection. Data analysis software is included to allow export data to a Laptop/Host computer and convert count distribution data to volume and surface area distributions. Data fitting routines are also provided to allow fitting of size distribution of data by monomodal, bi-modal and tri-modal distribution functions.

Scanning Wide-range Particle Spectrometer, 10nm-10um, 128 size bins

The WPS samples aerosol for measurement at the rate of 1.0 liters per minute (L/min). 0.7 L/min of this flow is sampled directly into the LPS for particle sizing and counting by laser light scattering. Simultaneously, 0.3 L/min of the sampled flow is directed into the DMA for size classification and particle counting by the CPC. While the DMA scans the aerosol for particle sizing between 10nm and 500nm, the LPS counts and sizes particles between 0.5um and 10um. The data are then sent to the internal, single-board computer for processing and storage. The instrument provides 12, 24, 48, 96 and 128 channels of size resolution. The WPS is recipe-controlled, allowing the scientist, engineer, or system manager to create as many recipes as required for a variety of aerosol studies. These recipes are then stored in memory to be recalled at any time, thus ensuring the same instrument settings can be used for data collection each time a given recipe is put into use.
