Product quality and pro­cess re­lia­bi­lity is es­sen­tial in re­gards of phar­ma­ceu­ti­cal water. LAR ana­ly­zers de­ter­mine con­ta­mi­na­tion re­li­ably in lowest levels meeting inter­na­tio­nal re­por­ting re­quire­ments.

Life Science

Water analysis of pharmaceutical water, as Purified Water (PW), Highly Purified Water (HPW) or Water for Injection (WFI) is of special concern in the life science industry regarding product quality and safety in process.

Depending on the res­pec­tive ap­pli­ca­tion, re­quire­ments re­gar­ding UPW purity are de­fined in norms as well as pharma regulations (pharmacopoeia).

Types of Pharmaceutical Water and their Limitations

Depending on its usage pharmaceutical water needs treatment with various filters and/or disinfection (see the schematic pharma water system above). Generally, there are three types of pharma water defined, :

  • Purified Water (PW) or Aqua Purificata
  • Highly Purified Water (HPW) or Aqua Valde Purificata
  • Water for Injection (WFI) or Aqua Ad Iniectabilia

International Pharmacopeias

In pharma industry the production of Purified Water (PW) and the maximum TOC (total organic carbon) level is defined by more than one authority.

The most popular pharmacopeias are:

  • Chinese Pharmacopoeia (CP),
  • European Pharmacopoeia (EP),
  • Indian Pharmacopoeia (IP),
  • Japanese Pharmacopoeia (JP), and
  • U.S. Pharmacopeial Convention (USP).

In the pharmaceutical sector water is inter alia used as

  • Cleaning agent
  • Excipient
  • Ingredient
  • Raw material and much more

Depending on its usage, pharmaceutical water needs a certain purity. 
Requirements on water quality and monitoring equipment are high.

  • Water for injections (WFI) is a demanding application of UPW in the pharmaceutical industry. In the manufacture of any type of active ingredient and medicine, the entire production process, including the cleaning process, is seamlessly monitored.
  • Highly purified water (HPW) is used as cleaning agent
  • Ultra-pure water (UPW) is often used as process water for the production of pills, capsules and other oral medication.

Purification of water

  • Even drinking water or potable water contain organics and other substances in very low concentration
  • pharmaceutically used water needs to be purified before it is used in manufacturing processes
  • The treatment of this so-called feedwater or make-up water takes place on-site and is very costly

  • Oil-in-Water (OIW) Analyzer


    LAR's OIW analyzer QuickOIL is a reliable online measurement system for the determination of oil in water. Due to the analyzers' innovative process design the analyzer determines the OIW content directly without dilution or memory effects. Moreover, it is suitable for every kind of oil, fat and grease - a huge advantage against common OIW methods.

    Easy. Fast. Reliable.

  • Certified Housings for Special Conditions

    In petrochemical or chemical plants explosive gasses, vapours or mist can be present. Therefore, LAR offers a wide range of analyzers with tailor made protective housing in accordance to international standards (IEC 60079-14:2007) and regulations (DIN EN 60079-2:2011-11). These stand-alone analyzers do not necessarily require air-conditioned shelters and they are made specifically for the use within hazardous, potentially explosive and corrosive environments.

  • TOC Analyzer for Pure Water Applications


    AR's TOC analyzer QuickTOCpurity is the most reliable measurement system for pure and ultra pure water applications. Due to a special injection loop, the sample is fully protected against contaminations from ambient air. Hence, the QuickTOCpurity reliably detects the TOC level of pure water.

    The combustion leader in TOC analysis provides maximum reliability and availability, hence also profitability for its operators.

  • TOC Analyzer for Pure Water Applications

  • TOC AnOnline TOC Analyzer


    LAR's TOC analyzer QuickTOCultra is the most reliable measurement system for the roughest waste water applications. Due to an unrivaled injection and oxidation technique, the QuickTOCultra easily handles sticky, fatty, salty, and high-particle samples unlike other TOC analyzers.

    The combustion leader in TOC analysis provides maximum reliability and availability, hence also profitability for its operators.

  • Online COD Analyzer


    LAR's chemical oxygen demand (COD) analyzer QuickCODultra is an outstanding measurement system for fast and clean COD measurements. Unlike traditional COD analysis methods, the QuickCODultra oxidizes water samples without the need of any hazardous chemicals. Due to the patented high-temperature combustion method, the measurement results are free of chloride inteferences. Moreover, the analyzer easily handles sticky, fatty, salty, and high-particle samples.

    Less chemicals. Simple operation. Save money.
