ALS has offered ultra-trace organics testing to the Water and Environmental sectors for well over a decade. Common suites tested include Ultra trace OC/OP pesticides, PCBs and PAHs or B(a)P plus a range of Carbamate, Triazine, Urea herbicide, Thiocarbamate and miscellaneous pesticides.
A few years ago ALS would have required 1,000mL for UT PAHs, plus 500ml for UT OC/OP/PCB plus 500mL for Multi-residues. In 2014, small changes were made to move to 500mL bottles. This latest change is a quantum shift in sample requirements following successful R&D and innovation projects.
From today, a single 100mL Amber bottle will suffice for UT OC/OP/PCB plus super UT PAH plus extended EP234 Multiresidues.
