Full Service Analytical Laboratory

complete environmental laboratory services

SOS Analytical, Inc. (SOS) was founded in 1993 as a full Service analytical laboratory. Formerly "Source on Site Analytical" , the company provided onsite geological and analytical services using a gas chromatograph with PID/FID detectors, housed in a mobile laboratory. The company then greatly expanded its services to include a full range of analytical capabilities. To reflect this expansion and increased staff expertise, the company name was changed to SOS Analytical Inc.


The professional staff has over 60 years of combined experience and specialized training in chemistry, mathematics, biology, geology, hydrology engineering and earth science. SOS provides complete environmental laboratory services using state of the art equipment, approved EPA methods and a superior quality assurance / quality control (QA/QC) program.

This facility is divided into four (4) separate analytical sub-laboratories, and includes all administrative, accounting and clerical functions. the laboratory is equipped with ventilation hoods that create a negative pressure in the building, preventing contamination caused by airborne solvents. The building complex also includes additional laboratory and administrative space to provide for growth and expansion.
