D3 Technologies has developed a cleaning verification procedure, which cuts swab and rinse analysis time from days to hours, significantly reducing production downtime. The test utilizes the companys patented Klarite substrate technology and Surface-Enhanced Raman Spectroscopy (SERS) know-how to provide a powerful new analytical tool to the pharmaceutical industry. It is a simple, easy to adopt procedure which provides highly reproducible results. The technology is capable of detecting trace quantities of analytes down to parts per billion levels. In addition, all components in an analytical mixture can be detected simultaneously, overcoming the need to search for contaminants. A robust calibration curve can be generated so that known analytes can be readily quantified.
