Whether it is routine work or more specialized testing, we understand the importance of obtaining dependable results in a timely manner. To meet the needs of our clients, Truesdail strives to timely deliver reliable data, including a standard 7-day turn-around-time plus options for expedited analysis. We pride ourselves on being experienced, dependable, and affordable.
Organic compounds are normally present in the environment as contaminants from industrial sources, with over a million synthetic organic compounds in existence. To detect organic compounds in soil, drinking water, wastewater, ground water and oil, Truesdail uses the latest instrumentation that is based on chromatographic techniques. Gas and liquid chromatography are used to separate one molecules from another, while the specialized detection systems are used to detect the separated compounds.
For the determination of volatile organic compounds (VOCs) including BTEX, Truesdail utilizes purge and trap/gas chromatography mass spectrometry (P&T/GC/MS). Truesdail uses detection systems such as flame ionization detection (FID) for the quantification and identification of petroleum compounds found in diesel and gasoline. The mass spectrometer allows molecules to be identified by their mass spectrum. The ion mass spectrum for molecules is often unique to a molecule just like our fingerprint is unique to us.
Inorganic Chemistry is the chemistry of all elements and their compounds that do not contain organic carbon by nature. Out of total 112 known elements, 92 of the elements are available in nature while the other 20 are man-made. To detect major and trace inorganic contaminants in soil, drinking water, wastewater, and ground water, Truesdail uses a combination of spectroscopic, electrometric, and automated colorimetric techniques. For the EPA regulated metals, Truesdail uses state-of-the-art inductively coupled plasma / mass spectrometer often referred to as ICP/MS. Truesdail specializes in metals analysis and has expertise in hazardous characterization of metals, including TTLC, STLC, TCLP, and CAM 17 metals analysis as well as with potable water analysis, including Title 21 and Title 22 analysis.
Bacteria, in particular coliform bacteria, are more durable and survive longer in water than most other pathogens. For this reason, presence of coliform bacteria serves as a primary indicator to the water and wastewater treatment industry’s effectiveness of water treatment (disinfection) processes. Coliform is present in the human body and are part of a healthy internal system. At Truesdail we use our microbiologist expertise along with state-of-the-art instruments to determine the presence/absence of these coliforms to accurately assess water quality and the success of water treatment. Truesdail also offers testing services for iron and sulfur reducing bacteria for corrosion in drinking water pipeline and chilling water systems.
At Truesdail we specialize in testing for Fungus Resistance. We use method Mil 508.6 comprised from Military Standard Mil-STD-810 and RTCA-DO 160. This method is designed by U.S Military and Air Force for quality assurance measures of test materials. These tests go through an environment of high humidity and temperature for a duration of 28 days to determine the development of five species of common fungus. Truesdail also offers services to ASTM G21, ISO B methods for fungus resistance testing which is design for commercial non-military test material.
Truesdail uses state of the art ion chromatography (IC) for the analysis of bromide, chloride, fluoride, nitrate, sulfate, and hexavalent chromium. Hexavalent chromium analysis on soil and water samples is one of Truesdail’s specialties. Using a combination of classical methods and bench chemistry, including colorimetry, gravimetric, and titrimetric techniques for tests such as ammonia, chloride, cyanide, phosphorus, silica, and sulfide. Truesdail also offers water general chemistry, wastewater, and soil analysis. Truesdail employs environmental chemistry for the analysis of Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand.
