| Handling of Ultra-Q water system |
1.0 OBJECTIVE To lay down a procedure for handling of Ultra-Q water system. 2.0 SCOPE This Procedure is applicable for the handling of Ultra-Q water system in Quality control department. 3.0 RESPONSIBILITY QC – Officer/ Sr. Officer 4.0 ACCOUNTABILITY Head-QC 5.0 PROCEDURE 5.1 Ensure the area is clear. 5.1.1 Ensure the purified water supply is continuing. 5.1.1.1 Ensure the supply is “ON”. 5.1.1.2 Switch“ON” the Ultra-Q water system, which is located on the back side. 5.1.1.3 The green light shows on front screen that supply is “ON”. 5.1.1.4 The system displays FLUSH PROSTD BY and ESC operate mode. 5.1.1.5 Make sure the water level of reservoir tank is not less than minimum level marking of purified water in reservoir tank. 5.1.1.6 When purified water fill uptohigh level marking of purified water in reservoir tank, system willautomatically cut-off. 5.1.1.7 If case water to be used for HPLC analysis (HPLC Water), take water directly from Ultra-Q water system. Press PRO to disperse water and Press ESC after collection of water. 5.1.1.8 Check online conductivity displayed on Ultra-Q water system and pH of water and record the observation in Format No. XXX. 5.1.1.9 Monthly cleaning of reservoir tank of Ultra-Q water system: 5.1.1.9.1 Keep Ultra-Q water system in ‘Stand by’ Mode. 5.1.1.9.2 Completely drain the Ultra-Q water from tank and rinse the tank with purified water. 5.1.1.9.3 Rinse the reservoir tank with hot purified water (Temperature NLT 70°C) 5.1.1.9.4 Finally rinse the reservoir tank with purified water. 5.1.1.9.5 Record monthly cleaning of reservoir tank in Format No. XXX. 5.1.1.10 If conductivity of Ultra-Q water system is observed more than 0.05 µS/cm, do not use water for analysis and intimate to service engineer for further action. In case of equipment breakdown, affix ‘Under Maintains’ label to instrument and intimate to service engineer. 6.0 ABBREVIATIONS > SOP – Standard Operating Procedure > No. – Number >QA – Quality Assurance >°C – Degree centigrade >NLT – Not less than >cm – Centimetres >µS – Micro Siemens |
