Aqualytical

Aqualytical specializes in in-situ water sampling and monitoring technology built around its flagship CLAM (Continuous Low-Level Aquatic Monitoring) device, a submersible time-integrative sampler that performs Solid Phase Extraction directly in the field per EPA Method 3535. Over deployments of 36 to 48 hours, a single CLAM unit extracts the equivalent of up to 100 liters of water onto SPE disk media, producing a time-integrated concentration profile rather than a single grab sample snapshot. The company offers two primary kit configurations: the CLAM 5000, which includes a redesigned spherical pump unit, digital volume totalizer with plus or minus 1 percent accuracy, rechargeable lithium battery providing up to 48 hours of operation, and 20 SPE disks in a fitted case; and the CLAM 4000, identical but without the totalizer. Supplementary tools include the Manual Syringe Tube and Disk for 1-liter field extractions and a Faucet Extraction Kit for pressurized water systems. Aqualytical provides multiple SPE media: C-18 Extraction Disks for pesticides, PAHs, semi-volatiles, PCBs, dioxins, furans, PBDEs, and oil and grease per EPA Method 1664; HLB Extraction Disks for pharmaceuticals, personal care products, endocrine disruptors, and emerging contaminants per EPA Method 1694; Lofted Glass Pre-Filtration Disks for TSS and total-versus-dissolved fraction analysis; and eDNA Disks with triple-lofted glass fiber filters for environmental DNA biodiversity studies. The system eliminates water sample shipping, bypasses 7-day holding time constraints, and achieves detection limits approximately 100 times lower than conventional 1-liter grab samples, serving groundwater, surface water, drinking water, agricultural runoff, stormwater, and marine monitoring applications.
