- Description
- STATEMENT OF REQUIREMENT This solicitation uses a Brand Name or Equal Description of the product required. This permits prospective contractors to offer products other than those specifically referenced by brand name. The VA St. Louis Health Care System is requesting a HPLC system, brand name or equal as listed below. The VA St. Louis Health Care System is requesting a HPLC system for research & development under the grant entitled: Synthesis, Characterization and Biocompatability of Hydrogel Vitreous Substitutes. Justification of purchase of a High performance liquid chromatography instrument for the Nathan Ravi lab: High-performance liquid chromatography (HPLC) is a technique in analytic chemistry used to separate the components in a mixture, to identify each component, and to quantify each component. Our laboratory is dependent on HPLC for many aspects of our work. Mainly, we use it for determining the purity of all of our materials that go into the synthesis of our polymers that are the basis of our vitreous substitutes for our VA Rehab merit review grant. We also use it for purifying materials after synthesis in our lab. Our HPLC instrument is old and has broken down and no longer supported by the initial manufacturer. We have exhausted our efforts in repairing it, and therefore we need to replace it. The schematic of an HPLC instrument that we require includes a sampler, pumps, and a detector. The sampler brings the sample mixture into the mobile phase stream which carries it into the column. The pumps deliver the desired flow and composition of the mobile phase through the column. The detector generates a signal proportional to the amount of sample component emerging from the column, hence allowing for quantitative analysis of the sample components. A digital microprocessor and user software control the HPLC instrument and provide data analysis. We need a model having mechanical pumps in a HPLC instrument can mix multiple solvents together in ratios changing in time, generating a composition gradient in the mobile phase. We require a variable wavelength UV detector that can record 2 wavelengths simultaneously. We need an HPLC instrument that has a column oven that allows for adjusting the temperature that the separation is performed.
