Our Project Managers. CT Laboratories firmly believes that communication is the key to every successful project. We will assign an experienced chemist as a dedicated Project Manager to handle all your needs. They can provide information for inclusion in your QAPP and can meet with you up front to discuss the project, making sure all questions and scenarios are discussed before the work arrives. Your PM will input your project-specific requirements (special compounds, reporting limits, action levels or report formats) into our LIMS. When the work arrives at the lab, you will be notified that the samples arrived safely and of their condition. Any problems, you will be notified immediately. After your reports have been sent, the project manager will be there to discuss the data with you. Learn more about Reporting and Electronic Data Deliverables here .
