Excellence in pharmaceutical TOC testing and vaccine quality control
Standard-compliant analysis according to international pharmacopoeias
Data integrity guaranteed
Extraordinary detection sensitivity and long-term stability
As a parameter for the quality and purity of water, the TOC content must be determined in international pharmacopoeias for various applications. It allows quick and reliable conclusions to be drawn about organic impurities and is therefore an integral part of the standards for ultrapure water control, cleaning validation and testing of extractable components from packaging materials for pharmaceuticals.
The multi N/C pharma series offers tailor-made solutions for this pharma-specific TOC analysis. A special device for total protein analysis in aqueous pharmaceutical solutions also offers a simple method for quality control of vaccines.
TOC ultrapure water testing and TOC/TN cleaning validation
The TOC ultrapure water test for water for injection (WFI) and Aqua purificata (purified water - AP) can be carried out in accordance with pharmacopoeias, e.g. USP <643> or EP 2.2.44, using high-temperature combustion or wet chemical UV digestion. In TOC cleaning validation, the same approach is used as a substance-independent method for the detection of organic residues, e.g. active pharmaceutical ingredients (API), additives and cleaning agents, on production equipment. multi N/C pharma offers solutions for both processes, whereby the devices for high-temperature combustion also allow the simultaneous determination of total nitrogen (TN) for cleaning validation.
Testing of extractable components from packaging materials
In order to ensure the suitability of polymer packaging systems for use in the pharmaceutical industry, USP <661.1> and <661.2> require the analysis of extractable components from the material or the packaging systems. For this purpose, ultrapure water eluates from the packaging materials or systems are tested for their TOC content according to USP <643>.
Quality control of vaccines
The total protein analysis in the production of vaccines by determination of the total nitrogen content according to e.g. USP <1057>, Method 7.2, enables the quantification of attenuated or devitalized viruses or bacteria as well as antigens. In the production of allergenic vaccines, this method can also be used to analyze raw materials such as pollen lyophilisates as well as different dosage forms such as desensitization vaccines, prick test solutions or sublingual drugs with one and the same TN test method.
