5 Sole Source Justification for the acquisition of a Monodisperse Aerosol Generation System and a Scanning Mobility Particle Sizer PI: Dr. Denisia Popolan-Vaida Department: Chemistry 1) Describe the product(s) and/or service(s) and anticipated use thereof in layman s language. Airborne soil organic particles (ASOPs) have been proven to play a significant role in the Earth s atmosphere, climate, air quality and public health. The objectives of my research are to understand the effects of ASOP in the atmosphere, to study how the heterogeneous reactions with important atmospheric oxidants will change their chemical composition, hygroscopicity, and optical properties after ASOP are lifted into the troposphere. For these investigations, sub-micrometer soil particles will be generated under laboratory conditions, by either atomization of soil suspensions in water or other organic components, and investigated under conditions similar to those in the upper atmosphere. Briefly, this experiment is proposing to understand the role ASOPs play in the atmosphere and correlate this with potential effects on climate and human health. The monodisperse aerosol generation system will be used to produce a monodisperse aerosol beam that will be further reacted into a flow tube reactor. The changes in the particle size during the chemical reaction in the flow tube will be monitored by means of a scanning mobility particle sizer. For the successful production of the ASOPs of a particular size and further detection of any changes in their size as a result of the reaction, we need a monodisperse aerosol generation system and a scanning mobility particle sizer system with the following specifications: Monodisperse Aerosol Generation System Should include an aerosol generator capable of producing a continuous flow of sub-micron aerosol particles The classifier sheath air flow should be adjustable from 2 to 30 lpm The classifier sample flow rate should be adjustable from 0.2 to 5 lpm Scanning Mobility Particle Sizer SMPS should be able to measure size distributions in the range from 1 nm to 1,000 nm The classifier sheath air flow should be adjustable from 2 to 30 lpm The classifier sample flow rate should be adjustable from 0.2 to 5 lpm CPC sample flow rate: 0.2 to 5 lpm CPC single particle counting: up to 10 7 particles/cm 3 CPC internal pump

6 2) (A) State in detail why only this and no other product(s)/service(s) will satisfy the department s requirements. We compared the instruments (MAGS and SMPS) manufactured by TSI incorporated, Brechtel, and Grimm Technologies (see Table below). Based on the instruments technical specifications only the MAGS 3940A-N and SMPS 3938L52 produced by TSI Incorporated meets the minimum requirements of our experiment. TSI Incorporated Brechtel Grimm Technologies Scanning Mobility Particle Sizer (SMPS) Specifications: SMPS 3938L52 SEMS:2100 SMPS+C Classifier sheath air flow yes no no adjustable from 2 to 30 lpm Classifier sample flow rate yes no no adjustable from 0.2 to 5 lpm CPC sample flow rate 0.2 to yes no no 5 lpm CPC single particle yes no yes counting up to 107 particles/cm3 CPC detection limit yes no yes CPC response time < 1.5 seconds yes no no Monodisperse Aerosol Generation System (MAGS) Specifications: 3940A-N SEMS: U Custom Classifier sheath air yes no no flow adjustable from 2 to 30 lpm Classifier sample flow rate yes no no adjustable from 0.2 to 5 lpm Requires diffusion dryers no yes yes (already included) Requires aerosol generation source no (already included) yes no (already included)

7 (B) State why the product(s) and/or service(s) are available from only one source and how that determination was made. Explain the research conducted to support this claim. To determine which of the instruments available on the market are able to satisfy the requirements of our experiment I performed an extensive literature search and discussed with several researchers that have instruments designed to produce and characterize aerosol particles in their laboratories. Based on the conducted research I concluded that only the TSI incorporated instruments have all the characteristics required in our experiment. The TSI Model 3938L52 Scanning Mobility Particle Sizer (SMPS) and the TSI Model 3940A-N monodisperse aerosol generation system are custom engineered, designed and built by TSI Inc. in Shoreview, Minnesota (USA). These instruments are only sold directly by TSI and its authorized international distributors. They are not available from any other supplier. The 3940A-N monodisperse aerosol generation system is design for the generation of monodisperse, sub-micron aerosol particles. It includes a 3082 Classifier, a 3081A Long DMA, 3074B Filtered air supply, a 3076 Atomizer, a 3062 Diffusion dryer and tubing. The 3940A-N monodisperse aerosol generation system is the only instrument available on the marketplace that includes all of the following required specifications: TSI Classifier offers sheath air flow adjustable from 2 to 30 lpm, allowing for higher size-selection resolution, while Brechtel offer sheath air flow from 2.5 to 12 lpm TSI Classifier allows for sample flow rate of 0.2 to 5 lpm, while Brechtel and offers smaller range of 0.1 to 2.0 lpm TSI Classifier offers color touch screens allowing for on-screen error messages to be shown in real-time while the Brechtel Classifier offers a digital screen with control knobs TSI Classifier offers auto-recovery in case of power failure while Brechtel Classifier does not The TSI Model 3938L52 is the only instrument available in the marketplace that includes all of the following required specifications: Uses continuous, fast scanning capability with minimum scan times of less than 4 seconds. Reliable, high-resolution particle size distributions can be collected in the shortest period of time. The system has a sheath flow range of 2 to 30 lpm for high-resolution sizing. The Brechtel offer sheath air flow range only from 2.5 to 12 lpm, while the Grimm Technologies system range from only from 3 to 20 lpm. The system has resolution of up to 128 channels per decade. The Grimm Technology system has only 64 channels per decade. The system has a relative humidity (RH) sensor in the sheath flow loop. The system is ISO compliant. The SMPS system includes a 3752 Condensation Particle Counter (CPC) to detect sizeclassified particles. It can classify or detect particles ranging from 10 nm to 1 μm. The CPC can act as a standalone particle detection instrument, detecting particles as small as 4 nm (Dp50). The CPC can measure concentration up to 1x10 7 particles/cm 3 with single particle counting up to 1x10 5 particle/cm 3.

8 The CPC can operate at 0.3 lpm or 1.5 lpm, while Brechtel and Grimm Technology CPCs offer single option of 0.36 lpm and 0.6 lpm, respectively. The CPC has a response time of <1.5 seconds. The CPC can measure data at 50 Hz. The CPC includes pulse height monitoring for improved diagnostic capabilities. The CPC has anti-flooding feature with auto-shutoff of pump. The system can auto-detect the provided impactor, neutralizer, DMA, and a variety of TSI CPC models, including the 3775 CPC. The impactor and DMA are designed for tool-free installation on the Classifier. TSI is an ISO-9001 certified manufacturer The system has stand-alone data logging capability with an internal hard drive and touch screen, and includes auto-recovery in case of power failure. TSI CPC offers pulse height monitor in order to more easily check data quality while Brechtel CPC does not. Includes TSI AIM software for use with a PC. (C) Provide an explanation to support the belief that the price is fair and reasonable. As already mentioned above, only the Monodisperse aerosol generation system and the Scanning mobility particle sizer system produced by TSI Incorporated have all the characteristics required for our experiments. The price of the systems produced by either Brechtel (~$97K) or Grimm Technologies (~$97K), that are not fully fulfilling the requirements of our experiments, is comparable with the price offered by TSI incorporated ($105K). Please note that the TSI Incorporated price includes the price of the Neutralizer K-85 ($8,935.00) required for the operation of the Monodisperse aerosol generation system. The Neuralizer has a lifetime of 10 years. Both, the Bechtel and Grim Technologies system requires neutralizers too. The price listed for these two systems does not include the neutralizers. These systems require a krypton-85 neutralizer that has a lifetime of only one year. So, new neutralizers have to be purchased every year.
