Bahrain tender for supplying and commissioning of transformer oil analyzers
SUPPLYING AND COMMISSIONING OF TRANSFORMER OIL ANALYZERS: DISSOLVED GAS, FURAN & PASSIVATION CONTENTS (Electricity Transmission Directorate)
STACK CONFIGURATION
The system should be arranged in suitable and compact stack configuration (solvent cabinet, detector, column compartment, auto sampler with thermostat control compartment, pump and controls) to optimize the flow path for minimum delay volume and minimum bench space.
BINARY PUMP
The HPLC must include a suitable pump with a pressure operating range up to 1200 bar. The HPLC pump must have a minimum flow range from 0.2 to 5 mL/min including connecting capillaries, solvent tray, maintenance and tool kit and integrated degassing unit. Binary Pump should combine active damping with lowest delay volume.
It must overcome the problems of pumping LC solvents at ultra-high pressure and high flow rates. It should contain heavy duty drive motors, with piston material to withstand the workload as well as to actively transfer heat from the seals, micro fluidic heat exchangers and a micro fluidic mixing device. It should have a solvent degasser to increase flow stability at low flow rates and detector sensitivity.
