The Maryland Public Health Laboratory in Baltimore located at 1770 Ashland Avenue does not accept patients or provide phlebotomy service for specimen collection for testing. Please contact your healthcare provider or local Health Department to order Zika or related lab tests.
Gas Chromatograph – Electron Capture Detector (GC/ECD) The ECD or electron capture detector measures electron-absorbing components (usually halogenated) by creating an electrical field in which molecules exiting the GC column can be detected by the drop in current in the field. The ECD uses a radioactive beta particle (electron) emitter in conjunction with a makeup gas flowing through the detector chamber.
Gas Chromatograph – Mass Spectrometer (GC/MS)Gas chromatography–mass spectrometry (GC-MS) is a method that combines two techniques to form a single method of analyzing samples. Gas-chromatography separates the elements of a sample and the mass-spectrometry characterizes each element making it possible to qualitatively and quantitatively analyze samples. The GC-MS is a system tailored to meet the rigorous demands for scientist in both routine analysis and research.
The laboratory analyzes pesticides, herbicides, haloacetic acids, PCBs, semi-volatile organic compounds in drinking water by various EPA. Pesticides, PCBs and semi-volatiles in wastewater, soil, hazardous waste, sediments, and sludge are analyzed by EPA method 8270 in support of State and federal environmental regulations.
