Q&A With Michael Vagell, Sartorius Corporation
Michael Vagell, Applications Support Manager at Sartorius Corporation takes a closer look inside laboratory water systems and how to properly maintain them in order to achieve the best performance.
Pharmaceutical manufacturers create formulations and tablets designed to dissolve at a specific rate after ingestion. There are many factors that can affect this rate including, but not limited to: a) the chemical species of the component materials, b) the chemical interaction between these materials, c) the physical properties of the material, and d) the physical properties of the final product.
Organic compounds and silica are the species least strongly held by the ion exchange resins. After a period of use, the ion exchange capacity of a purification pack starts to be used up and these compounds are released first even before the resistivity has fallen much below 18.2 MO-cm
In May, 2007, the International Standards Organization (ISO) introduced a new standard for the calibration of air and liquid particle counters. In preparation for this new standard, in late 2005 when the ISO 21501 standard was still in draft, Hach Company incorporated the standard’s performance criteria within the specifications for all air particle counter development projects.
When a certain temperature limit or storage time is exceeded, you run a great risk of loss and product write off. Continual insight into the conditions under which your products are produced, stored or transported reduces this risk.
