Apex Analytical Laboratory 

Air Testing


Air analysis for volatile organics is offered through our strategic alliance partner, AirTech Environmental Laboratory.  AirTech provides ambient air, indoor air, and soil vapor testing using methods from the USEPA Air Toxics Method Compendium.

Environmental Testing

Environmental sample testing is a core strength of Apex Environmental Laboratory.  Our staff has extensive knowledge and experience working on projects for engineering/consulting firms, municipalities, utilities, mining, chemical, waste management, transportation, electronics, and petroleum industries.  These projects include analytical test methods  from the following compendiums:


  • Test Methods for Evaluating Solid Waste, SW-846 (USEPA)
  • Methods for the Determination of Metals in Environmental Samples (USEPA)
  • Standard Methods for the Examination of Water and Wastewater (APHA, AWWA, WEF)
  • Methods for Chemical Analysis of Municipal and Industrial Wastewater (USEPA)
  • Methods for Determination of Inorganic Substances in Environmental Samples (USEPA)
  • American Society for Testing and Materials (ASTM)

Apex Environmental Laboratory is accredited by the Arizona Department of Health Services for compliance testing of drinking water, wastewater, groundwater, soil, and solid waste under the following regulatory programs:


  • Resource Conservation and Recovery Act (RCRA)
  • Clean Water Act (CWA)
  • Safe Drinking Water Act (SDWA)
  • Clean Air Act (CAA)
  • Toxic Substances Control Act (TSCA)

We specialize in metals and elemental analyses by ICP-MS, using the Agilent 7700.  This is the newest generation technology to provide low detection limits and accurate analyses of water, soil, and solids. 


The sample preparation area was designed with HEPA air filtration to provide a contamination free area for the analyses of trace metals in the low ppt - ppb range.
