To meet UPS <643> and EP 2.2.44 requirements. In cases of very low conductivity (<10 µS/cm), such as purified pharmaceutical waters, two compensations need to be made. [Note - There is a pH measurement (not a test) as a part of Stage 3 test for Water Conductivity <645>, but this is still a conductivity limit test]. We also offer support services such as sample collection and data trending. Purified Water (PW), Highly Purified Water (HPW), and Water for Injection (WFI) used in pharmaceutical Oxidisable Substances Test (water analysis) : To 100 ml of sample, add 10 ml of dilute Sulphuric Acid and 0.1 ml of 0.02 M Potassium Permanganate and boil for 5 minutes, the solution remains faintly pink. Acidity or Alkalinity . Some gases—notably CO 2 —readily dissolve in water and interact to form ions, which predictably affect conductivity. There are two basic types of pharmaceutical water; water for topical use or cleaning (sterle purified water, or PW), or water for injection(WFI) which includes sterile water for irrigation and most sterile water for inhalation. For example, antacids, which do not have an effective preservative system, require an action limit below the 100 cfu/mL maximum.” (3). Sterile Water for Injection, USP is a sterile, nonpyrogenic, solute-free preparation of distilled Water for Injection. Eur. Ammonium. Ensure that the 3KL RO water tank has more than 50% of the water level. Conductivity is a principal measure of water quality, as extraneous ions may have a significant effect on water’s chemical purity and suitability for use in pharmaceutical applications. It is for use only as a sterile solvent or diluent vehicle for drugs or solutions suitable for parenteral administration.

USP Pharmaceutical Water Testing Water is widely used as a raw material, ingredient, and a solvent in the processing, formulation, and manufacture of pharmaceutical products, active pharmaceutical ingredients and intermediates, compendial articles, and analytical reagents. A pharmaceutical-grade TOC analyser uses ultra-violet light (UV) to oxidise the organic molecules to release the carbon atoms present as carbon dioxide (CO 2) and then measures the difference in water conductivity caused as the carbon dioxide dissolves into the water. USP Standards for Packaged Purified Water, Water for Injection, and Sterile Purified Water (USP24 effective 1/1/00). Weaknesses in water systems are exacerbated by microorganisms being ubiquitous and varied in their ability to survive and grow under different conditions. TOC is a pharmaceutical measurement required when producing USP purified water, WFI (Water for Injection), and HPW (Highly Purified Water). Therefore, monitoring pharmaceutical-grade water systems for bioburden is important. Put on the UV sanitization unit and open the valve V07 to permit the purified water to 5 KL Purified water storage tank. We are concerned with two primary types of water: purified water and water for injections (WFI). Purified Water Parameter Unit USP Ph. Issuance of purified water analysis template: Before analysis, Register/log the sample, and generate/issue the worksheet, or the template. The conductivity of sea-water is typically 5 S/m, drinking water is typically in the range of 5-50 mS/m, while highly purified water can be as low as 5.5 μS/m (0.055 μS/cm), a ratio of about 1,000,000:1,000:1. The term ‘distilled water’ indicates Purified Water prepared by distillation. Water quality and analytical methods European Pharmacopeia EP US Pharmacopeia USP Japanese Pharmacopeia JP FDA (U.S. Food and Drug Administration) Guide to Inspection of high purity water systems 21 CFR 210/211, 21 CFR Part 11, 21 CFR 177 European Commission (EG) Guide to Good Manufacturing Practice PIC/S (Pharmaceutical Inspection Convention) Such an upper limit applies to the water is a multi-functional resource, crossing all disci-plines in the pharmaceutical industry. Pure water does not possess a lot of conductivity but as more ions are added the conductivity increases. Water For injection (WFI) Specification, WFI specification, ... Conductivity (at 25 0 C) Less than 1.3 µS/ cm. USP . NOTE— Purified Water is intended for use as an ingredient of official preparations and in tests and assays unless otherwise specified (see Water in Ingredients and Processes and in Tests and Assays under General Notices and Requirements).Where used for sterile dosage forms, other than for parenteral administration, process the article to meet the requirements under Sterility … 4.3 Purified Water is water for the preparation of medicinal products other than those that require the use of water which is sterile and/or apyrogenic. Water purification … Water is used as a raw material, solvent, ingredient, reagent, and clean-ing agent, and is produced in a variety of “pure” forms. ... chemical formula for that substance an upper limit exceeding 100 per cent may be stated. Conductivity can be applied quickly in-line or off-line, and it is very sensitive to the maximum allowable concentrations (ppb to ppm) of the chemical species of interest. The tests for Total organic carbon and Water conductivity apply to Water for Injection produced on site for use in manufacturing. Purified water is used in the pharmaceutical industry. dq for purified water system name of the system : pretreatment & purified water generation system table of contents sr. no.
