Laboratory Equipment

Lenge Purification Equipment Co., Ltd. and Jiangnan University established the Institute of materials and technology, and the graduate-student workstation. With advanced imported test equipment, standard test procedures and testing proposals, we can provide customers with various test and validation services, such as chemical compatibility, extractables, adsorption, bacterial challenge, bacterial viability, integrity, recycle use, etc.

For different customers, we simulate the produce process under the most disadvantage conditions, and make qualitative and quantitative estimation of dissolution by imported infrared spectrometer, ultraviolet spectrophotometer, HPLC and other equipment, thus make the quantitative analysis of the product absorbed on the membrane.

Purpose

Under the worst conditions, the qualitative analysis and quantitative estimates of dissolved matter from the filter in the contacting process of the technology.

Principle and method selection

The sources of dissolved matter include: the filter hardware, supporting layer, filter membrane, wetting agent and other additives maybe used in the processing. Extracted the filter from the model volatile solvent, by quantitative detection of non-volatile residue (NVR), and then qualitative analysis of ultraviolet-visible spectrum and infrared visible spectrum, if necessary, increase the analysis of dissolved matter.
