No mention of whether samples will be liquid or solid. There are three ways to do liquids (cheap, moderate, and expensive, with data quality correlating to the cost). Government Answer - The samples will be solid. Liquid sampling is not a requirement. Question 2. No mention of general elemental composition (the stoichiometry is important to insure the chromatography will work). Government Answer - The samples will be wide ranging as the unit will support a research and development facility. Many samples will fall into the nitrate ester, nitramine, and nitro-aromatic groups. Question 3. No mention of general sample size consideration. Government Answer - Sample sizes are generally in the 2 -3 milligram range. Question 4. It should be made clear that oxygen analysis is a separate undertaking from CHNS. This can be done either by converting over the CHNS instrument to an oxygen mode, or to have a separate oxygen analyzer. We provide both a conversion kit for a CHNS instrument, as well as a standalone O analyzer that can be bundled with a CHNS analyzer. Government Answer - The Government understands the oxygen analysis vs. CHNS. Offerors may propose their own solution as long as the solution meets all the requirements delineated in the Request for Quote (RFQ). Question 5. Combusting the sample will not happen in a sealed furnace. Government Answer - The Government understands the clarification. Question 6. Elemental analyzers won't "determine the simplest empirical formula of a sample to help confirm an unknown." It can only provide CHNS and O as a separate analysis. If other atoms are present, they cannot be measured or quantified, and so cannot provide a complete empirical formula. Government Answer - The Government understands the clarification. 7. An elemental analyzer can't "determine % Polymer in a co-polymer formulation or blend using a hetero-element." It will "Correct the result % on all elements (not "all" but only for CHNS-O) to a dry basis when the moisture content is known." Government Answer - The Government understands the clarification. All other terms and conditions remain the same.
