Go with the Flow (Rate) and Select the 1.4-Liter Canister

Our team of scientists recently completed the analytical study for air samples to compare analytical results between 6-Liter and 1.4-Liter Silonite™ Ceramic Coated canisters. The study was performed by collecting the same samples in both 6-Liter and 1.4-Liter canisters. A total of seven split samples were collected and analyzed.  Analytical data from the comparison study were in agreement; with an average relative percent difference (RPD) of only 4.6% for each of the 81 compounds analyzed by TO-15.  The results of the study confirm that it is not the size of the air sample collected that counts, but sample collection flow rate that actually matters.

Merit Laboratories is Michigan’s PFAS Laboratory

Merit Laboratories is Michigan’s environmental laboratory for PFAS analytical testing.  Merit offers two analytical options for PFAS: EPA 537 and ASTM D7979. Merit Laboratories performs EPA 537 in drinking water for the list of 14 PFAS substances that are EPA-approved by the method. EPA 537 is a prescriptive Drinking Water Method for 14 PFCs.  We also perform ASTM D7979, which is a method for non-drinking water matrices. Merit Laboratories can analyze for the MDEQ PFAS requested list of 24 PFAS substances using ASTM D7979.

Protecting our Water: Friends of the Shiawassee River

With over 36,000 miles of rivers and streams running throughout the state, Michigan is known for its plentiful freshwater and recreation opportunities. Over the years, many citizens and local groups have taken it upon themselves to serve as caretakers to protect these precious freshwater resources.  One such group is the Friends of the Shiawassee River (FOSR), which has been doing excellent work for over 20 years.

24-Hour TAT Support for the Northern California Wildfire Cleanup Program

Last October, wildfires ravaged Northern California covering a 245,000-acre path of destruction over a 24-day period. When the last fire was finally extinguished, nearly 9,000 homes and buildings were destroyed with total damages exceeding $12-billion as a result of the wildfires. Quickly, the U.S. Army Corps of Engineers went to work to begin a cleanup program that continued through March 2018.  

As part of the USACE cleanup program, Merit Laboratories performed analytical laboratory testing on more than 4,000 soil samples over multiple sample collection events that lasted several months.  All soil samples analyzed by Merit Laboratories were completed following an expedited 24-hour turnaround time (TAT) for heavy metals.
