Mark Noorani, Laboratory Director
Mr. Noorani is an environmental chemist with over 20 years of experience in the chemical industry including over 10 years experience as a bench chemist. As Laboratory Director, Mr. Noorani is directly responsible for all laboratory operations and business development.

Mr. Noorani has been involved in method development for Mass Spectroscopy products (i.e. High Resolution, Isotope ratio, and MS/MS mass spectrometry), Gas Chromatography using a variety of detectors such as PID, FID, NPD, PFPD, FPD, ELCD, ECD, and TCD; High Pressure Liquid Chromatography (HPLC) both UV and Fluorescent; Ion Chromatography, and Wet Chemistry. He also has extensive experience in air analysis (i.e. NIOSH methodologies and stationary source combustion samples.)

Mr. Noorani has an excellent knowledge of quality assurance and quality control (QA\ QC) requirements common to environmental laboratories. His expertise includes statistical data evaluation, calculation of control limits, audit of raw data, and coordination of QA \ QC requirements. With this working knowledge, Mr. Noorani is able to provide technical assistance to all laboratory personnel and provide competent and beneficial information during client consultation.

Mr. Noorani completed his chemistry degree at California State University at Fullerton. He is an active member of several professional associations including the American Chemical Society, Southern California Environmental Chemists Society and American Water Works.

Chris Tisserat, QA/QC Director
Mr. Tisserat has experience in environmental related chemistry as both a bench chemist and QA/QC director. He is responsible for monitoring the quality of the laboratory’s work and taking appropriate actions to ensure that quality standards are being met.

Mr. Tisserat is responsible for all aspects of quality assurance and quality control (QA/QC) coordination, implementation and evaluations. He is also responsible for the development of project specific QA plans. He has extensive experience with a variety of analytical techniques including Gas Chromatography (GC), Gas Chromatography/Mass Spectrometry (GC/MS), Atomic Absorption (Flame) and Infrared Spectrometry (IR). As a bench chemist, he has performed analysis on drinking water, wastewater, soil, sludge, and vapor samples utilizing the above equipment. Mr. Tisserat has also analyzed these matrices in mobile laboratories and is familiar with immediate response situations.

Mr. Tisserat reviews all data produced at Orange Coast Analytical for compliance with the EPA requirements and assessment of accuracy, precision, and completeness. As a QA/QC Director, he audits data packages prepared by the analysts, and all the laboratory procedures. Furthermore, Mr. Tisserat issues summaries of proficiency results, audit results and status of QA objectives and other QA information as needed for the laboratory director and the laboratory managers.

Mr. Tisserat completed his chemistry degree at California Polytechnical University at Pomona.
