    quantification_method: 'Counts at each size bin as determined by CPC is corrected for particle charging efficiency, diffusional losses of particles in the DMA, the DMA transfer function and diffusional broadening of the DMA transfer function, and the counting efficiency the CPC and inverted to produce size distributions, surface area concentrations and volume concentration.'
    calibration_method: 'Calibration occurs through addition of a known amount of seed, and subsequent comparison to pre-weighed filter samples collected at a flow rate of 14 LPM over a period of 30 minutes. Corrections can be applied to the observed volume concentration based on the mass collected.'

    uncertainty_estimation_method: 'Uncertainty of particle mass concentration is on the order of 30% based on comparison to filter collection. Uncertainty arises from corrections for particle charging efficiency, diffusional losses of particles in the DMA, the DMA transfer function, diffusional broadening of the DMA transfer function, and counting efficiency of the CPC used to convert the measure particle mobility distribution to particle volume concentration.'
