2026-11-03

The City of Raleigh ( COR ) is solicitating proposals from one or more firm ( s ) with which to contract for the following services : The purpose of this Request for Purchase is to acquire an algal toxin analysis instrument using a fully - automated ELISA analysis system . The instrument must be capable of using ELISA kits for the analysis of Cylindropermopin , Anatoxin - A , and Microcystins . The vendor must provide all initial consumables , minimum one day on - site training , and operational parts to start up the instrument . Upon installation , the instrument must achieve a passing curve with a correlation coefficient of no less than 0 . 995 for algal toxin analysis . SCOPE OF SERVICES Awarded proposer shall provide services , all as set forth in this RFP and more particularly described in this Section 4 . Instrument Analysis Overview • The system should have the capacity to hold a minimum of 15 samples and analyze cyanotoxins , specifically : Cylindrospermopsin , Anatoxin - A , and Microcystins . • The instrument must possess full traceability for long - term results storage , including calibration and reagent data . • It should be able to fit on a standard laboratory benchtop . • The instrument can hold up to all necessary reagents , with no adapters . • It must display a passing curve with a minimum correlation coefficient of 0 . 995 . Consumables • Consumables consist of ELISA ( Enzyme - Linked Immunosorbent Assay ) Kits that are utilized to detect and measure the concentration of cyanotoxins , specifically cylindrospermopsin , Anatoxin - A , and Microcystin . Each individual cyanotoxin of interest has a kit for analysis . • The consumables must meet the drinking water and wastewater requirements by having the ability to detect at or less than 0 . 3ug / L microcystins , 0 . 7ug / L for cylindrospermopsin and 0 . 150ug / l for anatoxin - a . These requirements are based on the EPA ’ s health advisories . The EPA has a health advisory level for microcystins of 0 . 3ug / L in young children and 1 . 6ug / L in school age children and adults . For cylindrospermopsin the EPA has established an advisory level of 0 . 7ug / L in young children and 3 . 0ug / L in school age children to adults . Although the EPA has not established a health advisory for anatoxin - a , our established limit is the detection limit of 0 . 150ug / l . Computer • Windows 10 or higher . • The computer will be imaged by the City of Raleigh IT team to comply with the city ' s network requirements . • Optional : Ability to connect to the network and operate offline will be determined at a later date with a meeting with the City of Raleigh IT department and the service engineer . Software • The vendor must complete the Vendor Security Questionnaire , an example of which is provided in Appendix V . • Advanced user settings for making changes to the method and software . • Audit trail for tracking changes and actions within the system . • Traceability for maintaining a record of processes and activities . • Date and time stamping of raw data for accurate documentation . Service and Installation • Certified installation by factory - trained service engineers • Preventive maintenance plans for future purchase • Service repair with remote capabilities for quick turnaround . Training • During installation , provide multi - user training with the option to record for troubleshooting and retraining . • Technical phone support must be available to assist the microbiologist . Warranty • A 12 ‑ month comprehensive warranty must be provided . • Coverage must include emergency repair and application assistance , as well as all travel , labor , replacement parts , and software revisions or upgrades . • Remote , web ‑ based , and telephone technical support must be available .
