  • Specialty Testing | Ct Laboratories

    Specialty Testing In addition to our routine analytical capabilities, CT Laboratories LLC offers specialty testing services and can help develop new procedures to suit your needs. ​ These analyses support various environmental regulatory programs, including: Resource Conservation and Recovery Act (RCRA) Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Superfund Clean Water Act (CWA) National Pollution Discharge Elimination System (NPDES) Safe Drinking Water Act (SDWA) Federal Program Support: Army Corps, National Guard, Coast Guard, Navy, Air Force Various State Regulatory Programs: Underground Storage Tank (UST), Landfill Monitoring, etc. Total, Fine and Coarse Lead by MDEQ SOP 213 This procedure is typically performed for EPA projects in order to characterize the lead fractionation of the soil (i.e., the fine & coarse fractions). ​ The Michigan Lead procedure involves sieving an air-dried soil sample into the coarse fraction (particle size > 250-µm) and the fine fraction (particle size < 250-µm). The % coarse and % fine values are determined via calculation. The coarse and fine fractions are then analyzed for lead via EPA 6010C. Finally, the total lead concentration is calculated via a weighted average of the coarse lead fraction and the fine lead fraction. Tissue Analysis: Pesticides, PCBs, Metals, Percent Lipids These internal methods are not certified by our accreditation agencies. These internal methods have been developed to fulfill client-specific needs and projects. Thiodiglycol and other Chemical Warfare Agent degradation products This method is designed to follow procedures developed in-house and to meet the requirements of EPA SW-846 method 8000 for ground water, surface water, and waste water. ​ A UPLC is employed in conjunction with a UV detector. Flame Retardants: PBB, HBB This method is designed to follow procedures and QC requirements found in EPA SW-846 method 8081B in order to determine quantities of HBB and PBB compounds found in a variety of sample matrices. HBB - Hexabromobenzene PBB - Firemaster BP-6 2,4- and 4,4- DDD, DDE, and DDT Breakdown products of DDT can be quantified using the 8081B methodology for pesticides. 1,4-Dioxane by 8270-SIM A Solid Phase Extraction methodology was developed for liquid samples using 8270D/E guidelines. The internal soil extraction method references 8000D. Invitro Bioaccessibility (IVBA) of Lead Internal method PR009 developed at request of EPA using SW846 1340 as a reference. ​ Contact us for more information. Back to Testing Services
