This bid is for two (2) Automated Purge and Trap Volatile Organic Compound (VOC) sample preparation systems. • The systems should accommodate a variety of sample types including drinking water, wastewater, soils, and sludges. • The three-stage, single needle design is capable of transferring liquid sample aliquots from the vial to the sparger, as well as purging low-level solid samples directly in the vial. • For high-level solids, the same needle is used to add methanol, mix, dilute and then extract to the sparger. Equipment must be equal to or better than what is described in the “Specifications and Conditions“. The following minimum specifications must be met in order to qualify for consideration for the bid. Any variation or exception to these minimum specifications must be explained in detail and item-by-item. OVERVIEW OF PURGE AND TRAP AUTOSAMPLER: 1) System must combine a purge and trap (P&T) and multi-matrix position autosampler into a single operating platform. 2) System must be compliant with USEPA methods 524.2, 524.3, 5030, 5035, and 8260 for the analysis of soils, wastewater and drinking water. 3) System must use a moisture control system (MCS) that reduces moisture by up to 60% over previous models. 4) Standard injection system must use dosing valves capable of varying volumes and generating no waste. 5) System must be capable of dilution options up to 1:100 for aqueous samples. 6) System must be capable of performing automatic blanks pulled from a separate reservoir. 7) System must be capable of automatic methanol rinsing, hot water rinsing with a dualstage water heater or a combination of both, for the entire sample pathway, allowing for the lowest achievable carryover. 8) System must have a sample syringe that dispenses variable volumes of liquid from 1 mL to 25 mL in 1mL increments. 9) System must employ an electronic mass flow controller (MFC) capable of varying flows for independent modes, in all matrix methods, including soil purging. 10)System must be capable of vial heating from 40 to 60 °C and soil mixing in variable speeds. 11)System must use a 3-stage concentric needle design. 12)System must be able to be controlled by a PC in Windows® 10 or higher environment SOFTWARE: 1) The software must be a 64 bit application for future upgradeability. 2) The software must be able to provide full automatic control of the process of analyzing samples. 3) The Software must allow real time integration monitoring for an instrument operator to monitor real time progress. 4) The instrument software must include self-diagnostic functions to readily identify proper installation and operation. 5) The software must be able to control and acquire data from third party instrumentation. SERVICE, INSTALLATION AND TRAINING: 1) The system must include installation of all equipment including checkout and verification of performance. 2) The system must include 2-day customer training and familiarization of all equipment and operating software at buyer’s site. 3) Service must be available from within a reasonable driving distance (4 hours) to allow for quick response. 4) Software phone support must be available during warranty at no cost to allow users quick access to trained software engineers.
