Vista first established its LC-MS/MS laboratory after receiving a request to develop a method for analyzing perfluorooctane sulfonic acid (PFOS) in human serum. Now, with over 15 degreed scientists in the department analyzing for over 40 different PFAS compounds, we have analyzed hundreds of clinical samples and tens of thousands of environmental samples for the various matrices listed to the right. Nearly every day you hear about another laboratory bringing this capability online with PFAS constantly in the news, but very few labs have the depth of experience and technical expertise Vista does. With four Ultra-Performance LC-MS/MS instrument configurations, Vista has the capacity to handle even the largest projects. We have processed and analyzed several thousand samples for the Michigan DEQ (now EGLE) to date.
