"Qualified Staff, State-of-the-Art Instrumentation & Quality Systems Guarantee Quality Data"
The Organic Chemistry Division (OCD) performs the analysis of trace organic compounds to provide sound scientific data for risk-based decision-making. To meet our goals of producing Quality analytical data and providing excellent Customer Service, all analyses are performed in accordance with LS’ ISO/IEC 17025:2005 accreditation requirements under its ISO 9001:2008 registered Quality Management System (QMS) and ISO 14001:2004 registered Environmental Management System (EMS).
Specific program areas include: drinking and bottled water compliance testing, soil and groundwater testing for trace organic contaminants, food analysis, and the qualitative identification and classification of contaminants from samples of unknown origin.
Drinking Water Compliance Testing
This service is provided to ensure that the drinking and bottled water used by military personnel and their family members both in garrison and during major operations in the theater meets or exceeds the regulatory requirements of either the Overseas Environmental Baseline Guidance Document, host nation specific requirements, or the Department of Defense Final Governing Standards.
Soil and Groundwater testing
The analysis of trace level organic contaminants in environmental samples allows the customer to identify and locate contaminated sites and to decide whether remediation (cleanup) is required.
For both the drinking water compliance testing and the soil/groundwater testing the following analyses are offered:
- Volatile Organic Compounds (VOC)
- Carbamate Pesticides
- Polychlorinated Biphenyls (PCB)
- Polycyclic Aromatic Hydrocarbons (PAH)
- Hydrocarbon Oil Index (HOI)
- Mineral Oil Content (MOC)
Analyses are performed using highly sophisticated, state-of-the-art analytical instrumentation:
- Gas Chromatograph coupled with Micro Electron Capture Detector (GC-µECD)
- Gas Chromatograph coupled with Mass Selective Detector (GC-MSD)
- Gas Chromatograph coupled with Flame Ionization Detector (GC-FID)
- High Performance Liquid Chromatograph equipped with Diode Array Detectors (HPLC-DAD), Fluorescence Detector (HPLC-FD), or Post Column Derivatization (HPLC-PCD) Unit
Qualitative Identification of Contaminants from Samples of Unknown Origin
This program is used to qualitatively identify the contaminants in a sample of unknown origin (e.g., a substance found during a deployment in an unmarked 55 gallon drum, a vat, unmarked container, etc.) as to the hazardous nature or composition of the material and potential threat to human health and the environment.
Typical testing procedures for the identification of unknown substances are:
- Boiling Point
- Melting Point
- Water solubility
- Water, Cyanide, and Sulfide Reactivity
- Heavy Metals
- Screen for organic contaminants
