ELAP Certification

Excelchem strives to ensure its clients receive the best environmental analytical service using appropriate testing methods and controls. We follow a comprehensive system of quality control measures adapted through experience in all aspects of laboratory operations. 

Excelchem’s quality control measures, modeled after Environmental Protection Agency (EPA) Manual SW-846, include the use of calibration blanks, calibration standards, method blanks, matrix spikes and matrix spike duplicates, internal standards, surrogates, and duplicated samples. In addition, Excelchem participates in the yearly analyses of EPA WS and WP reference samples. 


Our pricing policies are designed to meet a variety of needs.

Stationary facility prices are based on a 5-day standard turnaround: once Excelchem receives your samples, we get the results within 5 days.  Our mobile service price reflects no minimum number of samples needed or hidden costs (i.e. there is no extra charge for generator fees, per diems or excessive sample loads).  We will analyze as many samples as possible within a 10-hour day.  Excelchem’s services reflect our commitment to providing our clients with the highest quality services for the lowest cost.
