EEU Specification for HPLC (High Performance Liquid Chromatography)
Specification for HPLC (High Performance Liquid Chromatography) based test set to carry out Furan Analysis of insulating oils as per IEC 61198-93 and also as per ASTM-5837-99.
4. Water Purification System (to give HPLC Grade Water)
a) A three-stage water purification system to meet following requirements
(i) Input water Quality: Tap water from water taps available at laboratory having Conductivity: 1000-1500 uS/cm

(ii) Output Water Quality: Conductivity: 0.055 uS/cm (Resistivity > 18M-ohm-cm) TOC: < 5ppb

(iii) Capacity: 3 lit / hour

(iv) Power Supply: 220V ac, 1-ph, 50Hz

b) The system shall comprise of Pre-filtration stage, Reverse Osmosis Stage and Final Ultra pure water system with major specifications as follows:
(i) Pre-filtration Stage: Two-stage pre-filtration system to remove particles of sizes 5 microns and 1 micron respectively.

(ii) Reverse Osmosis Stage: The input feed water will be connected from above described Pre-filtration system. Reverse Osmosis stage shall consists of Inlet solenoid valve, Pretreatment pack, pressure regulator, Booster pump, Reverse osmosis cartridge with built-in decontamination port and conductivity cell, RO reject solenoid valve, pressure sensor, RO reject re circulation controller, conductivity cell, rinsing valve, Electrodeionisation (EDI) module and resistivity cell. The Output water shall be Analytical - Grade water with conductivity less than 0.2 S/cm and less than 30 ppb total organic carbon. The capacity shall be 5 liters per hour with 25% system recovery. All important system parameters shall be displayed continuously with audible alarm signal to enable auto diagnostics.

(iii) Final ultra pure water system: The input feed water will be connected from above described RO system. The ultra pure water system shall consist of a dual wavelength (185 nm and 254 nm) UV lamp to produce water with ultra-low levels of organic contaminants. The Output water shall have the Conductivity: 0.055 uS/cm (Resistivity > 18M-ohm-cm), and TOC: < 5ppb.

(iv) Sanitization Tablets: Chlorine Tablets - 50 Nos.
