Description
NOI-NIAID-24-2217058
NAICS - 334516
This is a Notice of Intent, NOT a request for proposal. The National Institute of Allergy and Infectious Diseases (NIAID) of the National Institutes of Health (NIH) intends to negotiate on an other than full and open competition basis with Wyatt Technology for the following:
DynaPro NanoStar II with MALS
Simultaneous DLS and SLS- The instrument must provide dynamic light scattering (DLS) and static light scattering (SLS) measurements simultaneously and independently in order to assess and distinguish changes in molecular conformation from aggregation, and to measure particle concentration. The NanoStar accomplishes this by design with parallel DLS and SLS detectors. SLS Calibration- The instrument must be calibrated for SLS measurements using a fluid such as toluene, commonly available with high quality and repeatability, rather than calibrated against a molar mass standard, because the latter technique depends on precise knowledge of concentration and refractive index increment of the standard in each specific solvent. As a consequence of the former calibration method, absolute rather than relative results will be obtained. The NanoStar, along with DYNAMICS or DYNAMICS Touch software, utilizes calibration by toluene when the quartz cuvette is installed. Temperature Control: The instrument must provide temperature control of the cuvette from at least -10 °C to +120 °C with precision and accuracy of ±0.3 °C or better, thermal stability better than 0.01 °C and programmable ramp rates in the range of 0.01 °C to 15 °C per minute. The NanoStar utilizes a Peltier element with extensive thermal management to meet this requirement. Measurement Range-The range of measurement of hydrodynamic radius by DLS must cover 0.2 - 2500 nm. The NanoStar accomplishes this by design and testing has proven that this range is addressed. The range of measurement of molar mass by SLS must cover 300 - 1, 000, 000 g/mol. T...
