Water and solvent system
training & resources.

List the water quality your equipment requires, your daily consumption and your simultaneous peak flow. Use these inputs to size generation, storage and distribution for their different duties.

Prepare your equipment list, operating hours and likely simultaneous draws. Include your feedwater information, delivery pressure, distribution route and planned growth.

Identify which use points need polishing beyond your central supply. Your instrument and equipment specifications determine the treatment required at each location.

Your analyzer, washer, preparation method or production equipment defines your water requirements. Record the specified quality and test criteria before comparing treatment systems.

RO uses a membrane separation process; DI removes dissolved ions. An RO/DI system combines these treatment approaches. Additional treatment may be needed for a particular use point.

Confirm your applicable standard and equipment specifications with your technical team. Bring your defined requirements to PPT for a Spec Review.

List your current solvents and expected additions. Identify your dispensing locations, available installation space and connections to gloveboxes or other research equipment.

Compare compact, cabinet-mounted, free-standing and hood-installed formats against your layout. Include your inert-gas supply, ventilation requirements and service access in installation planning.

For help with your installed equipment, send photos, your configuration and the part or operating issue you need reviewed.

Ion-exchange resin removes dissolved ions from water. DI is often combined with other treatment steps; it does not remove every type of contaminant.

Water is evaporated and the vapor is condensed into a separate stream, separating it from many impurities.

A filter retains particles as water passes through. The filter medium and pore size determine what it can capture.

Pressure drives water through a membrane that reduces dissolved salts and other contaminants. RO produces a treated stream and a concentrate stream.

A membrane process used to separate fine particles and larger molecules from water. It addresses a different range of contaminants from dissolved-ion removal.

Ultraviolet light can be used for microbial control or organic reduction, depending on wavelength and system design. These are distinct treatment objectives.

ASTM D1193 specifies reagent-water requirements. Confirm the applicable edition, water type and test requirements for the intended application rather than relying on a general purity label.

The College of American Pathologists provides laboratory guidance relevant to water quality. Use the current requirements for the laboratory and its connected equipment; historical type labels alone are not a system specification.
