PSA - Model N118A200 -Injection Valve Module
The PSA N118A200 injection valve module is designed to be used as part of an automated speciation system.The N118A200 is a stainless steel, 6 port 2 position air actuated injection valve mounted in a module for stability. The internal surface have been coated to ensure all contact surfaces are inert.The unit is used in conjunction with the PSA 10.025 Millennium Merlin or PSA 10.055 Millennium Excalibur, the PSA 20.400 Autosamler and SAMS Software for reproductible chromatograms using HPLC based speciation systems.
The AutoSAMS software initiates the N118 valve which turns the sample position while simultaneously the PSA 20.400 Autosampler is triggered to take the sample and fill the sample loop on the valve. The valve then turns to inject the sample at the same time starting SAMS Software to collect data. At the end of the chromatographic run, the valve is triggered to take the next sample and data collected is processed by the SAMSCalc software.
A typical automated speciation system would use a 500 µL coated sample loop but a full range of sample loops are available.
