Sampler Analyzer MR250

The Nano-ID Mass Reader MR250 is a companion product for the Nano-ID Select used to determine mass distributions quickly and without the need for laboratory analysis. The MR250 provides seven channels of resolution in the microparticle range of 250 nm to 20 μm and mass sensitivity of less than 10 ng.

New Optical Detection and Analysis
The instrument is designed specifically to analyze samples collected on glass slides from the Nano-ID Select, and therefore no sample preparation is necessary. The MR250 uses the light scattering characteristics of aerosol particles to quantify the masses of samples taken with the Nano-ID Select instrument for particles in the size range of 250 nm to 20 μm*. The method is also completely non-destructive and can therefore be used in combination with other analysis methods such as ICP-MS, XRF, or atomic absorption spectroscopy to give chemical composition and concentration information.

FEATURES

High Sensitivity and Immediate Mass Distribution Results

• Mass results can be produced immediately after the aerosol sample has been collected with 10 ng sensitivity
• The method is also completely non-destructive and can therefore be used in combination with other analysis methods such as AAS, ICP-MS, XRF, and SEM

Easy to Configure and Use

• Comes with easy to configure software that displays mass distributions
• The MR250 is a light-weight, fully portable desktop instrument and can be powered from a mains supply or for up to 10 hours from the internal rechargeable battery.

Flexible Calibration
Used in combination with the Mass Reader software, mass-size distributions can be easily calculated for calibrated aerosols. Default calibrations are provided for samples consisting of atmospheric aerosol, Arizona Test Dust, pure multi-walled carbon nanotubes (Arkema Graphistrength® C100), and pure titanium dioxide (Aeroxide® TiO2 P 25). Users can calibrate the MR250 to measure mass-size distributions for their own aerosol samples providing the mass of sample on the slides can be measured by another means, for example by gravimetric or inductively coupled plasma analysis. Optical readings are obtained for each stage from the Nano-ID using the MR250. The corresponding masses are determined by the chosen analysis method. The Mass Reader software plots the measured masses against the corresponding optical readings to get a calibration curve and calculates the parameters of a user-selected fitting function. Each stage from the Nano-ID Select must be calibrated separately since scattering properties change significantly with particle size.
