Full Service Lab
Shelton Associates has an in-house analytical lab (with a dedicated lab service manager) to support customers and field representatives. We can quickly and efficiently perform extensive analytical water testing. In addition to a state-of-the-art inductively coupled plasma mass spectrometer (ICP-MS), we can run in-house ion chromatography (IC) alongside a wide range of bench-scale tests.
Further, Shelton Associates can perform bench-scale membrane tests and membrane autopsies (complete with FTIR and SEM results).

Bench-Scale Applications Lab
In addition to our analytical testing equipment, we have an in-house applications lab, enabling us to test all types of membranes using small volumes of test solution. We can test MF, UF, NF and RO membranes in flat-sheet, spiral, hollow-fiber and tubular configurations. We can also test various pretreatment chemistries. Our qualitative applications lab complements our quantitative analytical lab.
Our Bench-Scale Equipment Includes:
1812 Spiral Test Apparatus (high pressure and low pressure)
Flat Cell Test Units (high pressure and low pressure)
Hollow Fiber MF/UF Test Units
Tubular Polymeric & Ceramic MF/UF/NF Test Units
Polymeric Membrane Distillation Units

Membrane Troubleshooting
In addition to supplying capital equipment and servicing existing systems, we also provide the following services:
Offsite membrane cleaning (2.5” – 8” diameter spiral elements) at our facilities
Membrane cleanings studies
Destructive membrane autopsies
Accelerated lifecycle testing of new membranes
Benchtop and field testing of membranes in new applications or changing operating conditions
