Through this Request for Proposal ( RFP ) the Office of Purchasing & Contracting ( hereinafter the “ State ”) is seeking to establish contracts with one or more companies that can provide Inductively Coupled Plasma Optical Emission Spectrometer ( ICP - OES ), chiller , autosampler , computer and software for the Metals Laboratory . DETAILED REQUIREMENTS : ICP - OES Instrument Specifications The Vermont Agriculture Environmental Laboratory ( VAEL ) requests proposals for an Inductively Coupled Plasma Optical Emission Spectrometer ( ICP - OES ), chiller , autosampler , computer and software for the Metals Laboratory . This system must be capable of performing feed & fertilizer analyses and EPA method 200 . 7 . The instrument must allow for calibration and detection of multiple analytes in a single sequence . 2 . 1 System Requirements : 2 . 1 . 1 Must include a new , bench - top fully automated system , with a footprint less than 35 ” x 30 ” x 25 ” ( H X D X W ). 2 . 1 . 2 Must have a simultaneous , solid - state detector with the ability to detect > 95 % of the wavelengths in the 167nm - 785nm range . 2 . 1 . 3 The detector should be chilled to at least - 35ºC to minimize dark current signal , enhancing instrument performance and detection limits . 2 . 1 . 4 The detector must be hermetically sealed and require no gas consumption for detector purging . 2 . 1 . 5 Must have dual viewing modes with the option to read axially and radially in a 2 - step sequential process or read axial and radial views alone . 2 . 1 . 6 The ICP - OES must use Argon ( 99 . 99 % purity ) only for operation . Total system gas flow for operation should not exceed 25 L / min . 2 . 1 . 7 All gas flows controlling the plasma should have Mass Flow Controllers . This includes plasma gas ( coolant ), auxiliary gas , nebulizer gas and make up gas . 2 . 1 . 8 Must have a water chiller . 2 . 1 . 9 Autosampler must be capable of holding at least 180 - 15mL autosampler tubes with a well for automatic sampler probe rinsing between samples . 2 . 1 . 10 The system must include a computer with Windows 11 operating system and manufacturer software capable of running all system components . 2 . 1 . 11 The instrument must have a standard single piece design vertical plasma torch 2 . 1 . 12 The instrument must have a five ( 5 ) channel , variable speed , and computer - controlled peristaltic pump to allow for on - line addition of internal standards . 2 . 1 . 13 Customizable , fully serviceable sample introduction setup including but not limited to torch assembly , spray chamber , nebulizer . 2 . 2 Instrument Software Must be capable of the following : 2 . 2 . 1 Automated background correction , removing the user ’ s need to decide upon suitable background points for background correction . 2 . 2 . 2 Automated spectral interference correction . For Traditional Interfering Element Corrections ( IEC ), the software must be able to automatically calculate these values . 2 . 2 . 3 Displaying a continuous full spectrum scan . 2 . 2 . 4 Flag out - of - control data 2 . 2 . 5 Track maintenance components . 2 . 2 . 6 Shut down system automatically after a sequence has ended . 2 . 2 . 7 Meets or exceeds method analysis requirements for SW - 846 and EPA Method 6010D & EPA 200 . 7 . 2 . 2 . 8 Export data and instrument files to a Laboratory Information Management System ( LIMS ).
