Here at Brooks Rand Labs, we have noticed many of our Canadian clients are working under new discharge permits with lower method detection limit (MDL) requirements for total mercury (Hg). Some water quality guidelines are even demanding site-specific detection limits as low as 0.10 ng/L for Hg. Brooks Rand Labs is able to comply with these new requirements, offering a 0.10 ng/L MDL for all clients (worldwide) for Hg analysis via EPA Method 1631E. There is no additional charge for this low-level MDL. If your project requires ultra-low level MDLs (for any analyte), contact us today!
