The final date and time for the submission of bids is Friday 16th December 2016 at 14:00 am DO NOT apply directly to the buyer. All tender information MUST be submitted through the CCS eSourcing Portal. Item Description SCANNING MOBILITY PARTICLE SIZER with long DMA (10 to 1000 nm) and Advanced Aerosol Neutralizer (Soft Xray) The item being procured is an instrument to measure particle size distributions of aerosols in the nanometer range and the Soft Xray neutralizer essential for its operation. It must permit the measurement of both number concentration and complete size distribution of nanometer-sized particles in a minimum of 10 seconds. The instrument must be able to measure particles down to 2.5 nanometers. The detector within the particle size spectrometer must be a butanol based condensation particle counter with a lower sensitivity of 2.5 nm and proven 50% efficiency at that size. The spectrometer must include a choice of at least two DMA's that can be interchanged quickly. Please ensure you review all attached information to ensure a full understanding of this requirement. All attachments can be found with the RFx attachments tab within the Emptoris System. This contract will be awarded based on the evaluation criteria set out in the ITQ document.
